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.

Features

Input – 12 V @ 1A
LED 12V 500mA Maximum (6W)
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
