The sensor detects the intensity of sunlight inside and outside buildings. It can be used where it is necessary to balance solar radiation using heating, ventilation and air conditioning systems . Its use is particularly advantageous in buildings with a large glazed area or in buildings exposed to strong and long-lasting radiation. The sensor senses the level of radiation with a photocell and transforms it into an electric current corresponding to the given level. It sends the measured data in this way with an output signal in the range of 4 ... 20 mA or 0 ... 10 V to any device capable of receiving this signal and processing it.
