Automatic door sensor light circuit diagram. This is a light sensor circuit which will detect light and switch on the relay. In this video you will learn how to make light sensor or what is known as automatic street light , as always its easy, simple and fun to make.

To make the light level at which the led switches on adjustable, you will also need a 100k trimpot.

15 Automatic Light Sensor Circuit Diagram. The ldr controls the transistor, then the transistor controls the regulator ic through the common terminal (gnd). Dark sensor with variable resistor In this circuit pir (passive infrared ) motion sensor is used which is used as a motion detector. If the led lights up, the ldr resistance decreases causing the scr to conduct periodically earlier.
