In this beginner tutorial, you are going to learn how to build a simple automatic lighting circuit using a Light Dependent Resistor (LDR) and Arduino. There are many applications of this circuit such as, Getting the lights in your house to turn on automatically when it's dark and turn off when it is day; A simple automatic streetlight, etc
Here in this project we are going to make a Simple Automatic Street Light Controller Using Relay and LDR. This circuit is simple and can be built with Transistors and LDR, you don't need any op-amp or 555 IC to trigger the AC load.
These are the things that we need for this project. We things are easily available in local hardware or electronic shop. First we study the circuit diagram of the automatic street light. Circuit diagram for Automatic Street light: This is a circuit diagram of Automatic Street light. Let try to understand this circuit. First start form battery.
Automatic 40 Watt LED Solar Street Light Circuit Updated: June 11, 2019 by Swagatam Today solar panels and PV cells have become very popular and in the near future we would possibly see everyone of us using it in some or the other way in our life.
Circuit Diagram of a Light Dependent Resistor. The circuit diagram of a LDR is shown below. When the light intensity is low, then the resistance of the LDR is high. This stops the current flow to the base terminal of the transistor. So, the LED does not light.
Automatic Street Light Controller Circuit Using Relays and LDR Did you ever think that how the street lights automatically turn ON in the night and turn OFF automatically at morning? Is there any person who comes to ON/OFF these lights?
In case of this automatic LED night light switch, we should save energy so I design this with main parts below: 1. LDR or photoresistor is used for sensor light-activated. It is cheap and easy to use. 2. A CMOS Digital-IC No.CD4069 is a inverter gate every useful and cheap.
Summary of LDR circuit for automatic light system: This circuit is based on Light Dependent Resistor (LDR) which 'll turn on LED's when ever darkness is sensed in room. You can put this small lamp in your kid's room as a simple emergency lamp to avoid panic situation in case of sudden power failure.

These circuits can be used for different automatic light sensing projects including automatic night lamp, automatic street light controller, dark sensor circuits, etc. Automatic night lamp circuit using IC 555 and LDR. An automatic night light circuit controls the switching of light by sensing the surrounding light intensity.
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).

Working Principle of LDR. A light dependent resistor works on the principle of photo conductivity. Photo conductivity is an optical phenomenon in which the materials conductivity is increased when light is absorbed by the material.
An Automatic LED Emergency Light circuit is designed to turn ON when there is no adequate lighting or if the power supply is cut-off. Earlier fluorescent lights were used to build such circuits. But the use of LED's have proven to provide adequate lighting for a longer period before draining the ...
This is the simple and cost effective automatic LED Emergency Light Circuit with light sensing. This system charges from main supply and gets activated when main supply is turned OFF. This emergency lamp will work for more than 8 hours (depending the battery capacity and the power consumed by the LEDs).
sir,we want automatic street light controller by using timer and counter.we want controlling the street light as follows,day time-6.30a.m to 6 p.m-light off,6.30 p.m to 7.30 p.m-light glows alternately,7.30 p.m to 6 a.m-light on,6 a.m-7 a.m-light glows alternately.So please send related circuit diagram,we are waiting for your circuit diagram.
An all-in-one automatic voltage battery charger circuit is discussed in the following post; the circuit can be modified in many different ways as per individual requirements and a
Dark Sensor ( light sensor / automatic street light ) Here is my new simple Electronics project about Automatic Street Light Control System or Dark Sensor. it is a simple and powerful concept, which uses transistor ( BC 547 NPN) as a switch to switch ON and OFF the street light system automatically .

Circuit Diagram and working of Automatic Street Light Controller Switch Using Relays and LDR. It automatically turns on and off street lights.
In this simple project, we are going switch ON a LED automatically during night time or when we moved into a dark room. To complete this project we need light dependent resistor (LDR), 10K potentiometer, LED, 150 ohms resistor, BC547 transistor or any general purpose transistor.
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.

However, when light falling on LDR is of large intensity, the resistance of LDR falls and the voltage drop across VR 1 is large enough (more than ½ Vcc). Thus, output of IC 1 become high. This high output drives the transistor in off state and as a result relay become de-energized. PCB Diagram of Light Sensor Switch Circuit using LDR and 741 IC
