LM393 Light Detection Sensor Module (4-pin LM393 LDR Digital & Analog)
  • LM393 Light Detection Sensor Module (4-pin LM393 LDR Digital & Analog)

#222: LM393 Light Detection Sensor Module (4-pin LM393 LDR Digital & Analog)

R23.10


LM393 LDR module for Arduino to detect the level of light/darkness. 

  • 1 Photosensitive Resistance module's most sensitive to ambient light, commonly used to detect environment around the device.
  • 2 The sensivity of the auto-trigger can be changed or can be read by an Arduino as analog voltage.
  • 3 the DO output can be directly connected to a microcontroller, through single chip microcomputer to detect the high and low
  • level, thus to detect the environment light intensity changes;
  • 4 the DO output can be directly driven out a relay module, which can form a light-operated switch.
