Board Schematic

Pin details 

  • VCC = 3.3V to 5V DC
  • GND = Ground
  • DO = Digital Output
  • AO = Analog Output

How to use

  • Photosensitive resistor module most sensitive to environmental light intensity is generally used to detect the ambient brightness and light intensity.
  • Module light conditions or light intensity reach the set threshold, DO port output high, when the external ambient light intensity exceeds a set threshold, the module D0 output low;
  • Digital output D0 directly connected to the MCU, and detect high or low TTL, thereby detecting ambient light intensity changes;
  • Digital output module DO  can directly drive the relay module, which can be composed of a photoelectric switch;
  • Analog output module AO and AD modules can be connected through the AD converter, you can get a more accurate light intensity value
