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.
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.
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.
Basic Electronic Project - Automatic Street Light Control System Components & Schematic Circuit Diagrams for Automatic Street Light Control System More information Automatic Street Light Control System.(Sensor using LDR & Transistor BC 547.)
We previously made many Circuits using LDR, which use LDR to automate the lights according to requirement. Working of LDR controlled LED using Arduino. As per the circuit diagram, we have made a voltage divider circuit using LDR and 100k resistor. The voltage divider output is feed to the analog pin of the Arduino.
This triggers the alarm and shows a burglary attempt. A lamp is also used to indicate the theft when light falls on the sensor. In future, this project can be developed by using a GSM modem and also a microcontroller. This modem can be interfaced to send an SMS to the user in case of burglary. LDR Based light Intensity Control for Street Lights
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
Automatic night lamp as the name suggests is for turning ON and OFF the lamp automatically without the need of human interventions. It senses the light intensity from surroundings and find whether its day or night.
LDR light sensor circuit, there was a problem with the LDR, it was turning the LED on with 5V instead of 12V, thiswas with using 10k Ω. Then I used 100Kthe LED was dim until it Ω and reached 9V. Relay Timer Circuit, all the connections were right, but I did not know how to use the relay 12v then I
An introduction: Needs no manual operation for switching ON and OFF. When there is a need of light it automatically switches ON. When darkness rises to a certain level then sensor circuit gets activated and switches ON and when there is other source of light i.e. daytime, the street light gets OFF.
Light sensor and street light control using Arduino is designed to measure the intensity of light or amount of light. Street light is controlled automatically with the help of the intensity of light and Arduino. Arduino UNO R3 is used in this project. Light-dependent resistor is used for the detection of light.

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).
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.
