4Pin LDR Module – Optical Sensitive Resistance Light Detection Sensor Module

  • Using the sensitive type photoresistor sensor
  • The comparator outputs a signal clean, good waveform driving ability more than 15mA.
  • With adjustable potentiometer can adjust the light intensity detected
  • The working voltage: 3.3V-5V
  • The output format: Digital switching output (0 and 1)
  • With a fixed bolt holes for easy installation
  • Small PCB board size: 3.2cm x 1.4cm
  • Using a wide working voltage range LM393 comparator
  • Application: Light intensity is detected, the light intensity sensor, smart car search light module

 Features: 

  • 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.
  • Analog output and AD module, through AD conversion, can obtain more accurate values of ambient light

Pin Configuration: 

  • VCC for positive power supply 3.3-5V
  • GND for power supply is negative
  • DO TTL switching signal output
  • AO analogue signal output

Package Includes:

  • 1x 4Pin LDR Module
