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
