  • With fixed bolt hole for easy installation
  • Small board PCB size: 3cm * 1.6cm
  • Power indicator (red) and the digital switch output indicator (green)
  • Using LM393 comparator chip, stable

Pin outs:

  • External 3.3V-5V VCC
  • External GND GND
  • DO digital output interface, a small plate (0 and 1)
  • AO small board analog output interface
  • 电源指示/PWR-  Power Indicator, 开关指示/SIG – Status indicator

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 values
