Dark Sensitive LED Light

Dark activated LED light is a simple project which operates a LED when the light falling on the LDR goes below a set point.  The circuit is built using LM393 comparator, LDR as light sensor, preset (potentiometer) for sensitivity adjustment, transistor to drive the LED. The project can also be considered for use in energy saving application.

  • Onboard Preset for Level Adjust
  • Operation LED Indicator
  • On Board Power LED
  • Header Connector for Power Supply and LED
  • PCB dimensions 55.45MM X 12.70 MM
