    Soil sensor and procedure to detect the amount of dirt on a surface. A sensor (20) for detecting the amount of dirt on a surface, comprising: a transparent surface (21) exposed to dirt; a light emitter (22) for emitting a beam towards the transparent surface; a first light receiver (23) and a second light receiver (25); means (24) between the light emitter (22) and the transparent surface (21) configured to pass a part of the light from the emitter to the transparent surface (21) and to redirect the rest of the light towards the second receiver ( 25); means of acquisition and processing (26). The first light receiver (23) is configured to receive the diffused light upon hitting the dirt on the outer face (21e) of the transparent surface (21). The acquisition and processing means (26) are configured to calculate a percentage measure of the degree of soiling of said transparent surface (21).
