The E human indoor temperature is up to about 40-41 ° C even e 30 in extreme heat and in other parts of sauna, such as A walls and benches generally there is at least 60 C or N more. If there are enough consecutive images, or video N frames, in which a person is detected and position in the consecutive images has not changed, processor 101 may be configured to understand to trigger alarm communications.
[0036] [0036] According to embodiment, the detector 104 comprises photocell or motion detector. The sauna may be fitted with enough photocell rays so that human being inside sauna is positioned inside it so that there is always at least one photocell ray being disturbed by human presence. Consequently, person's presence in the sauna can be seen as a difference from a situation where there is no disturbance in the rays. When the processor 101 determines that there is a person in the sauna, it starts motion detection. If processor 101 does not receive any detection change by the detector 104 for predetermined time, such as long period of time, IS processor 101 triggers alarm communications.

[0042] [0042] Alternatively or in addition to above, the processor 101 may also detect sauna stove being on and heated. The processor 101 may also detect that door of sauna is closed.
[0043] [0043] At 202, timer is running. Timer may be set to predetermined time. It may be long enough so that no false alarm may be given. However, it may not be too long so that human medical condition starts to be affected resulting from temperature and humidity or dehydration inside sauna.
[0044] [0044] At 203, human motion detection inside sauna is performed. Detector 104 may detect motion of human. Processor 101 may perform with detector 104 motion detection for predetermined time. If motion is detected within predetermined time, process return to operation
[0046] [0046] At 207, the device 100 is configured to perform safety action. This may be turning off heating of sauna stove. This may also or in addition be controlling door of sauna so that door is forced to open position. These action may decrease sauna temperature and reduce any damage caused by temperature and moisture or dehydration to humans.
[0047] [0047] At 205, at any point device 100 may detect human leaving sauna. Detector 104 may be configured to detect human moves outside sauna. According to embodiment, there may be a specific detector configured to detect human exiting sauna. The process end at 206 after detecting all persons have leaved sauna.
