Light sensor
— the light sensor provides additional automation for turning on/off the extractor fan. In particular, it automatically starts ventilation when the light is turned on in the room. Switching off can be carried out by a combination of a sensor and a timer — after the light is turned off, the fan continues to work for some time and turns off only after the period for which the timer is set has passed.
