Dark Sensor Circuit

Dark/Light Activated Circuit using LDR The dark sensor circuit is very useful to Automatic Switch ON and OFF any appliance by Detection of Light and Dark. LDR is a photoresistor that is used for the detection of light. When Light intensity high on LDR, The Resistance through it Decrease and When Light intensity is Low on LDR, then the resistance […]

Automatic Night Lamp Using LDR

LDR darkness sensor circuit dark sensor circuit  This Automatic light operated light switch circuit is Based on LDR. LDR is a Light Dependent Resistor. It is also called Photoresistor. Introduction of LDR LDR (Photoresistor) is a type of variable resistor which Increases its Resistance when the Light is Decreases and its Resistance Decreases When Light is Increases. It means in […]
