Photosensitive Brightness Resistance Sensor LDR Module
KSH 200.00
In Stock
The LDR (Light Dependent Resistor) module is a sensor that detects light intensity, with resistance decreasing as light increases and vice versa [citation:1][citation:2]. It features a photoresistor, LM393 comparator, and a potentiometer for sensitivity adjustment [citation:8][citation:2].
