Product Discription

05-August-2018

A light detector senses light. As the level inceases adn LDR meets the lowest threshold resistance, the circuit automatically turns on the LED D1. we can adjust the senstivity using the resisance.

 

LOW resistance > less darkness to switch off the LED

HIGH resistance > more darkness to switch off the LED

A dark detector can be made using variable resistor, the sensitivity of the circuit can be adjusted using with a varicable resistor.
