The LU201 Illuminance Detector can continuously monitor the environmental illuminance inside the cover, and convert the measured value into a linear proportional signal output. The instrument uses a high-precision silicon photocell as the sensing element. The optical signal is converted into an electrical signal by a professionally designed cosine corrector and a special high-efficiency filter to the sensing element, and then processed by a highly integrated circuit to output a continuous linear proportional signal.
