R28.35


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.

Product Details

  • 1 Using photosensitive resistance sensor sensitive type;
  • 2 Working Voltage:3.5V-5V;
  • 3 Output form:Digital Switch show (0 and 1);
  • 4 Fixed Bolt Hole,easy installation;
  • 5 Small PCB size:3.2CM*1.7CM;
  • 6 the comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma;
  • 7 with adjustable potentiometer to adjust light brightness;
