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).
Fig. 1 Block diagram of street light system . 2 Automatic street light system circuit design The system basically consists of a LDR, Photoelectric sensor, Power supply, Relays and Micro controller. 2.1 LDR The theoretical concept of the light sensor lies behind, which is used in this circuit as a darkness detector.

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.
This small day night switch can switch on any Electrical device automatically when Dark falls and switch off in the morning automatically. Just install this smart LDR - Dusk to Dawn sensor Twilight switch at your home, office, Warehouse, Factory or Farm and watch your electricity bills cut down.
This simple Light Dependent Resistor circuit diagram construction and working principle with applications. LDR to make an LED turn on and off depending on the light. dark sensor using relay and AC The circuit of #LDR is an #electroniccircuit built with LDR, relay, Darlington pair, diode, & resistors See more
The distance between my leds and ldr is much nearly 5-6 cm because of which when a laser beam strikes the ldr the led turns onn but asa lazer beam is switched off led also switches off .. i want that when ldr is triggered once and led is turned on then untill an unless we remove the battery led continues to light .
Introduction. In this project, I will show you how to build a simple Light Activated Switch Circuit using LDR. Using this circuit, an electrical device or an appliance like a light bulb or a fan for example, can be controlled based on the intensity of the light near the circuit.
Within this flashing led light circuit, the LDR otherwise photoresistor is connected in such way with the intention of at what time the light intensity varies it desire influence the flashing frequency and the brightness of the LEDs. T1, T2 = BC547, BC548, BC549 (whichever NPN transistor).
Now, let us discuss how to make a light sensor circuit. The automatic light sensor circuit can be designed using various electrical and electronic components.The major components used in this circuit are light sensor (LDR), Darlington pair transistors and a relay.
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 ...
presents an automatic street light controller using light dependent resistor(LDR). By using this system manual works are removed. The street lights are automatically switched ON when the sunlight goes below the visible region of our eyes. It automatically switches OFF the street lights under illumination by sunlight.

Smart Streetlight Using IR Sensors Sindhu.A.M, Jerin George, Sumit Roy, Chandra J Dept. of Computer Science, Christ University, India Abstract: Smart Street light is an automated system which automates the street. The main aim of Smart Street light is to reduce the power consumption when there are no vehicle movements on the road.
This automatic staircase light circuit switch on the staircase lights automatically when someone enters on the stairs and gets off after some time. There are two important components in this circuit, first is PIR Sensor (Passive Infrared Sensor) and second is Relay.
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
