    Module Instructions 

    • Photosensitive resistor module most sensitive to environmental light, generally used to detect the 

    • brightness of ambient light, triggering microcontroller or relay module; 

    • When ambient light intensity does not reach the threshold value, the module DO-side output high 

    • when the ambient light level exceeds the set threshold, DO terminal 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 changes; 

    • DO output can directly drive the relay module, which can be composed of a light control switch. 

    • Product wiring instructions: 

    • VCC for positive power supply 3.3-5V 

    • GND for power supply is negative 

    • DO TTL switching signal output
