Product description format_size zoom_out zoom_in

Principle of operation: when the light hits the photoresistor, the sensor is inactive and the light is off. In the absence of light on the photoresistor, the circuit turns on with a pop or other loud sound, and turns off with some delay. The delay time is set by the components R2, C2. If the photoresistor is illuminated when the circuit is on, it will turn off instantly.
Board size 37 * 22.5mm
