Capacitance Operated Battery Powered Light Wiring diagram Schematic

Build a simple Capacitance Operated Battery Powered Light Circuit Diagram. Capacitance is the ability of a body to store an electrical charge. Any object that can be electrically charged exhibits capacitance. A common form of energy storage device is a parallel-plate capacitor. Touch the plate and the light will go on and constant of the 47 µf capacitor and the 2M remain on for a time determined by the time resistor.

Simple Light operated switch Wiring diagram Schematic

This is a Simple light-operated switch schema diagram.This light sensitive schema can operate a relay to switch on lamps or any AC loads when it senses darkness.

 It is ideal to use as switch less night lamps. This schema uses a flip-flop arrangement of Ql and Q2. Normally Ql is conducting heavily. Light on CDS photocell causes Ql bias to decrease, cutting it off, turning on Q2, removing the remaining bias from Q1. Reset is accomplished by depressing S1
