Light Sensor Circuit Diagram with Working Operation

Light Sensor Circuit Working Operation. The light sensor circuit is an electronic circuit designed using (light sensor) LDR, Darlington pair, relay, diode, and resistors which are connected as shown in the light sensor circuit diagram. A 230v AC supply is provided to the load (in this case, the load is represented with a lamp).

Automatic Street Light | Seminar Report, PPT, PDF for ECE ...

This is done by a sensor called Light Dependent Resistor (LDR) which senses the light actually like our eyes. It automatically switches OFF lights whenever the sunlight comes, visible to our eyes. Aim of this seminar is to control the street light using LDR. When the light falling occur means resistance value will be change.

Automatic Room Lights using Arduino and PIR Sensor

In this project, we will see the Automatic Room Lights using Arduino and PIR Sensor, where the lights in the room will automatically turn ON and OFF by detecting the presence of a human. Such Automatic Room Lights can be implemented in your garages, staircases, bathrooms, etc. where we do not need continuous light but only when we are present.

Light Activated Switch Circuit Working with Applications

In case of the street lights erected on highways it is not an easy task to manually control them, but, if uncontrolled, the chances of power wastage would increase. To get rid of this situation, the implementation of automatic light switch by using a light sensor that switches lights automatically on and off is the best option. Light Sensor

Automatic Light Operated Switch using LDR and IC741 ...

Circuit description of automatic light operated switch using LDR and IC741. The circuit presented here is light operated circuit using LDR. LDR is a semiconductor component whose value of resistance is changed according to the intensity of light falling on it i.e. more the light falls on the LDR, the less the resistance is and vice-versa.

Transistor as a Switch Using LDR - Peter Vis

A light-dependent resistor (LDR) provides a switching signal to a transistor to control a load. Simple transistor circuits with LDR are very common and used in many applications such as a night light and emergency lighting. The transistor may directly control power to an LED or bulb, or may drive a relay.
