Photoresistor (LDR) Light Sensitive Sensor Module,
Photosensitive resistor module most sensitive to ambient light, generally used to detect the brightness of ambient light, triggering microcontroller or relay modules. When the brightness of ambient light module can not reach the set threshold, DO-side output high when the ambient light level exceeds the set threshold, DO end output low. DO output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting the brightness of ambient light to change , DO output of the relay module can directly drive the shop, which can be composed of a light control switch
