    The invention relates to a method for determining the temperature and humidity of a building with at least one temperature sensor for measuring the temperature of the building and at least one moisture sensor for measuring the moisture of the building.
    The invention further relates to a device for determining the temperature and humidity of a building, comprising at least one temperature sensor and at least one moisture sensor.
    In various structures, in particular screeds, the measurement of the so-called micro-climate, especially the temperature and humidity, important or even mandatory to the time of subsequent work, in particular the time of covering the screed with a floor covering (so-called slip) without damage to the flooring to be able to determine by inadmissible high humidity values of the screed. In other structures, such as facades, the condition of the facade, in particular their moisture, for subsequent insulation work or painting work of importance.
    Previous methods and devices for determining the temperature and humidity of a structure are associated with a partial destruction of the structure by attachment of boreholes or the like. For example, DE 36 41 875 A1 describes a method and a device for the continuous determination of temporally variable moisture distributions in components, wherein a measuring lance having a plurality of temperature and humidity sensors is introduced into a borehole in the component.
    EP 0 901 626 B1 also describes a method and a device for measuring the moisture in building materials, wherein corresponding sensors are introduced into a borehole in the building material.
    When measuring moisture in screeds to determine the readiness for use, the s.g. CM method established as standard, which requires the arrangement of boreholes in the screed. Such methods are thus relatively time consuming and costly and also often inaccurate.
    After covering a screed with a floor, especially wooden flooring, it is possible to non-invasively record the environmental parameters in order to more reliably determine the causes of any damage to the floors. For example, EP 1 817 529 B2 describes such a device and a method for detecting environmental parameters in floor coverings and a floor covering with such a device.
    Here, for example, inadmissibly high temperatures or moisture values in the floor can be determined and subsequent costly expert reports to ascertain the causes can be prevented. An impermissibly high humidity of the screed, however, can not be determined with this method, or only too late, namely after the laying of the floor.
    Non-destructive moisture measurements, for example via the measurement of the impedance of the structure, usually have impermissible inaccuracies.
    The object of the present invention is to provide a method and an apparatus for determining the temperature and humidity of a building, in particular screed, which is as simple, quick and reliable feasible and as simple, inexpensive and robust constructed. Disadvantages of known methods and devices should be avoided or at least reduced.
    The object of the invention is achieved in terms of the method in that on the surface of the structure a water vapor diffusion-tight volume is formed, and measured after reaching a state of equilibrium, the temperature and humidity with the at least one temperature sensor and the at least one moisture sensor in the water vapor diffusion-tight volume and for determining the temperature and moisture in the building is used. The inventive method is thus characterized by the formation of a water vapor diffusion-tight volume following the structure to be tested, whereby after a certain period of time adjusts a state of equilibrium by the water vapor diffusion comes to a standstill. As a result, the temperature and humidity values measured in the water vapor diffusion-tight volume can be equated to those in the structure to be tested, for example screed. Thus, a relatively rapid, clean, non-destructive and reliable determination of the temperature and humidity values in the building is possible. The measurement of humidity is usually the measurement of relative humidity.
    Advantageously, the temperature and humidity of the ambient air is measured. This provides important additional information about factors that influence the drying process of the building.
    For further processing and subsequent use of the data, the measured values of temperature and humidity are preferably stored. Thus, the measured values are available for later documentation or further processing.
    Likewise, the measured values of temperature and humidity can be transmitted to a receiver. In this way, the measured values can be forwarded to the processing points continuously or else at any time. The transmission can take place to receivers in the immediate vicinity of the device, for example by means of Bluetooth® or NFC (Near Field Communication) or also via mobile or Internet technologies to more distant recipients.
    The water vapor diffusion equivalent air layer thickness (sd value) of the water vapor diffusion-tight volume is at least 1000 m, preferably at least 10000 m. A certain minimum density of the water vapor diffusion-tight volume is required in order to achieve the equilibrium state in the shortest possible time. By suitably suitable adhesives, the tightness can be made relatively quickly and easily. When selecting the adhesives, it must be ensured that, in addition to the water vapor tightness and good adhesion properties on the surface of the building, a relatively simple distance from the building is possible later on.
    The water vapor diffusion-tight volume can be easily formed by adhering a sealed chamber to the surface of the structure.
    Alternatively, the water vapor diffusion-tight volume can also be formed by a cup-shaped receiving device, in which receiving device parts of the structure are introduced. This alternative method allows a faster determination of the measured values, but requires a partial destruction of the structure, since the parts of the building, which are introduced into the receiving device, must be generated.
    It is advantageous if the temperature of the receiving device is kept constant or is almost identical to the temperature of the building or screed. This can be done in particular by a thermal insulation of the cup-shaped receiving device.
    Furthermore, the temperature of the receiving device can be controlled by a heater to perform the measurement of the temperature and humidity of the parts of the structure under controlled conditions can. For this purpose, for example, resistance heating devices come into question, which are connected to form a control loop with corresponding temperature sensors.
    If the position of the water vapor diffusion-tight volume is determined, on the one hand the measuring point can be clearly defined and on the other hand an illegal change of the position and, for example, a theft of the device can be displayed.
    The object of the invention is also achieved by an above-mentioned device for determining the temperature and humidity of a structure, wherein on the surface of the structure a water vapor diffusion-tight volume is formed, arranged in which water vapor diffusion-tight volume of the at least one temperature sensor and the at least one moisture sensor and a microprocessor is connected so that after reaching a state of equilibrium, the temperature and humidity in the water vapor diffusion-tight volume for determining the
    Temperature and humidity in the building is used. Such a device is relatively simple and inexpensive and can be produced with a small size. For the further advantages, reference is made to the above description of the method according to the invention for determining the temperature and humidity of a building.
    Advantageously, at least one temperature sensor for measuring the ambient temperature and at least one moisture sensor for measuring the ambient humidity is provided and connected to the microprocessor. These measurements provide important information about the environmental conditions that influence the drying process of the structure.
    The water vapor diffusion-tight volume may be limited by a ring on which ring an adhesive layer for fixing is arranged at the top of the building. The ring preferably has the shape of a circle, but other, for example triangular, square or polygonal shapes are possible. At any point of the water vapor diffusion-tight volume is an opening in which, possibly protected by a membrane, the temperature and humidity sensor is arranged. In this case, separate temperature and humidity sensors or combined temperature and humidity sensors can be used.
    When the microprocessor is connected to a memory, readings are retained for later use or documentation.
    If the microprocessor is connected to a transmission device, in particular a mobile radio module, a direct or later transmission of the measured values to specific receivers can be carried out. For example, a GSM (Global System for Mobile Communications), UMTS (Universal Mobile Telecommunications System) or LTE (Long Term Evolution) module can be used in the device in order to be able to connect to a mobile radio network.
    Furthermore, the microprocessor can be connected to a display in order to be able to reproduce certain operating states or measured values. The display can be realized by one or more LEDs or an LCD display possibly combined with an operating option in the form of a touch screen.
    If the microprocessor is connected to an interface, measured values can be transmitted to the outside or updates can be made to the device. For example, the device may be equipped with a USB (Universal Serial Bus) interface. In addition to wired interfaces and wireless interfaces come into question.
    According to a further feature of the invention, an anti-theft device is provided. On the one hand, such an anti-theft device can be made mechanically by connecting the measuring device to the examining structure or screed, which, however, entails a partial destruction or influencing of the structure, for example by providing anchors or hooks. In addition to mechanical anti-theft devices, it is also possible to realize electronic anti-theft devices, for example in the form of motion sensors and audible and / or visual warning devices. As already mentioned above, an anti-theft device can also be made by monitoring the position of the device, and in the event of an unforeseen change in position, an audible and / or visual warning or even a message to a control center (for example by SMS, e-mail or the like). be delivered.
    If a receiving device is provided for receiving parts of the structure, which receiving device forms part of the water vapor diffusion-tight volume, the temperature and humidity of the building can be determined more quickly. However, a partial destruction of the structure is necessary to obtain the parts for the receiving device.
    The invention will be explained in more detail with reference to the accompanying drawings which illustrate embodiments of the invention. Show:
    Fig. 1 is a perspective view for illustrating the
    Arrangement of the device according to the invention for measuring the temperature and humidity of a building in the form of a screed;
    2 shows a side section of an embodiment of a device according to the invention for measuring the temperature and humidity of a building in the form of a screed;
    3 shows a view of the device according to FIG. 2 from below; FIG. 4 shows a block diagram of a device according to the invention for measuring the temperature and humidity of a building; and
    Fig. 5 shows a variant of the device according to the invention with attached receiving device for receiving parts of the building.
    Fig. 1 shows a perspective view for illustrating the arrangement of the device 1 according to the invention for determining the temperature and humidity of a structure 2 in the form of a screed. The structure 2 or the screed has a certain height hE on which the duration of the drying depends. The device 1 of the invention is simply applied to the surface of the structure 2 or screed, in particular glued, whereby a water vapor diffusion-tight volume 5 is formed by after a certain time tGg an equilibrium state, so that measured in the water vapor diffusion-tight volume 5 and moisture in the Essentially corresponds to the temperature TE and moisture FE of the screed. The time tGg for reaching the state of equilibrium depends largely on the height hE of the structure 2 to be examined, and the size of the volume 5 which is impermeable to water vapor diffusion. With usual screed heights hE of 5 to 6 cm and a diameter of the water vapor diffusion-tight volume 5 of 1.5 times the screed height hE, ie about 9 cm, the achievement of the equilibrium state, for example, in a few days to a week is expected. With knowledge of the respective time courses, however, a reliable inference to the temperature and humidity in the structure 2 can be made even before reaching the equilibrium state by applying appropriate corrections. Thus, on non-invasive and non-destructive method quickly and easily the temperature and moisture history of the screed can be determined and thus reliably the time are determined point from which a floor covering can be easily arranged on the building 2 and screed. Applications on other structures 2, in particular facades for determining the condition of the facade, for example, for determining the ideal time for the attachment of an insulation or paint layer, are also conceivable.
    At the structure 2 or screed also several devices 1 for determining the temperature TE and moisture FE can be placed, which can also communicate with each other. In addition, the data of the devices 1 can be forwarded to a receiver 9, from which a transmission of the measured values can take place at arbitrary locations, for example in the Internet. If a transmission device 14 (see FIG. 4) is arranged in at least one device 1, the direct transmission of the measured values to a remote receiver 9 can take place.
    FIG. 2 shows a side section of an embodiment of a device 1 according to the invention for determining the temperature and humidity of a structure 2 or screed. The device 1 for determining the temperature TE and moisture Fe of the structure 2 comprises a water vapor diffusion-tight volume 5, which is formed by arranging the device 1 on the surface of the structure 2. The water vapor diffusion-tight volume 5 is limited for example by a ring 6, preferably a circular ring 6, laterally and through the housing of the device 1 at the top. Assuming a corresponding tightness of the volume 5, a state of equilibrium arises after a time that is significantly dependent on the height hE of the structure 2 or screed, and the temperature and humidity measured in the water vapor diffusion-tight volume 5 can be used to determine the temperature TE and moisture FE in the structure 2 or screed are used. For measuring the temperature and humidity in the water vapor diffusion-tight volume 5, an opening 8 is arranged in the housing of the device 1, behind which the temperature sensor 3 and the humidity sensor 4, possibly a combined temperature and humidity sensor is arranged. The temperature sensor 3 and humidity sensor 4 is connected to a microprocessor 10, which tet the data appropriately and at most in a memory 13 stores. To measure the ambient temperature TD and ambient humidity FD, further temperature sensors 3 and humidity sensors 4 can be arranged, which communicate with the environment via a corresponding opening. For preferably adhering the device 1 to the surface of the structure 2 is a corresponding adhesive layer 7, which may be formed by a liquid or pasty adhesive, possibly on a carrier layer. The adhesive is selected to achieve the tightness of the water vapor diffusion-tight volume 5 and to achieve a corresponding adhesion to the structure 2.
    Fig. 3 shows a view of the device 1 according to FIG. 2 from below. The ring 6 for limiting the water vapor diffusion-tight volume 5 is preferably circular, but may theoretically be triangular, square, rectangular or in the form of a polygon.
    FIG. 4 shows a block diagram of a device 1 according to the invention for measuring the temperature and humidity of a structure 2 or screed. In addition to the previously described microprocessor 10, which is connected to the temperature sensors 3 and moisture sensors 4 and a memory 13, a power supply 11 is provided, which may be formed in particular by corresponding accumulators. About a charging plug 12, the batteries can be charged. A transmission device 14 connected to the microprocessor 10 is used for preferably wireless transmission of the measured values to corresponding receivers 9. A GPS (Global Positioning System) module 16 connected to the microprocessor 10 can determine the position of the device 1 and also this information, in particular in the case of Using a variety of devices 1, store and transmit along with the temperature and humidity readings. Furthermore, an interface 17 may be connected to the microprocessor 10 in order, on the one hand, to be able to read out data from the device 1 or also to be able to import new data or software updates into the device 1 or the microprocessor 10. The interface 17 can be formed for example by a USB interface. A display 15, for example LEDs or an LCD display or a touchscreen, can be used to output warning signals, operating states or measured values. An anti-theft device 18 can lead to an optical or audible warning in the event of an undesired change in position of the device 1.
    Finally, FIG. 5 shows a variant of the device 1 according to the invention with a cup-shaped receiving device 19 connected thereto for receiving parts of the structure 2 or screed. In this embodiment, the device 1 is not placed on the surface of the structure 2, but arranged the cup-shaped receptacle 19 on the device 1 and thereby the completed water vapor diffusion-tight volume 5 is formed. For example, the
    Receiving device 19 are screwed or attached to the ring 6 of the device 1. Parts 20 of the structure 2, for example a screed, are introduced into the receiving device 19, whereby a state of equilibrium is established already after a short time tGG and the measured temperature and humidity correspond to those of the structure 2 or screed. The receiving device 19 may be surrounded by a thermal insulation 21 in order to reduce an influence of the measured values by changes in the environmental conditions. In addition, a heating device 22 may be provided in order to be able to set and regulate the ambient conditions and to be able to produce comparable measuring conditions. In the variant of the device 1 according to FIG. 5, however, a partial destruction of the structure 2 or screed to obtain the parts 20 of the structure 2 is necessary. For this, the method provides faster measurement results than non-invasive laying on or sticking to the surface of the structure 2 according to FIG. 1.
