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.
Automatic LED Street Light Using Electronics LDR Sensor - Electricity DIY Project - Hello Friends, here I will show you how to make LED street lighting using LDR electronics sensor. This is the ...
These energy saving street lights make use of incandescent lamps instead of LEDs.So here I will teach you how to make an electronic circuit for street light automation. The heart of this circuit is a LDR (Light Depended Resistor) which is connected as a potential divider with a 56K resistor.
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.
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.

Circuit Diagram 1. Automatic Street Light Control System.(Sensor using LDR & Transistor BC 547.) Very Simple. We have tried this one in this tutorial but you can also try the second one mentioned below.
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 dark detector senses darkness. As the light level decreases and LDR meets the maximum threshold resistance, the circuit automatically switches on the LED D1. Dark sensor with variable resistor: A dark detector can be made using a variable resistor. The sensitivity of the circuit can be adjusted with a variable resistor.
Automatic Street Light Dimmer Using Motion Sensor will save power by reducing its brightness when no one is passing in the road, PIR sensor will detect the motion in the road. The signal from the PIR sensor will activate the circuit and increase the brightness, this street lamp circuit not using microcontroller thus we can reduce cost.
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).
How The LDR Circuit Diagram Works. The LDR circuit diagram works like this: When it's dark, the LDR has high resistance. This makes the voltage at the base of the transistor too low to turn the transistor ON. Therefore, no current will go from the collector to the emitter of the transistor.
Here based on our room condition the threshold value we took is 100 for the LDR sensor. When we place a hand on LDR(Not allowing any light on LDR) arduino automatically turns on the LED. When we remove our hand on LDR. Arduino automatically Turns Off LED.
The circuit of an automatic night light described in this article can be used to put OFF a light when day breaks and switch it ON back when darkness sets in. Learn how simple it is to build a 12 volt day night switch.
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).
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.
Automatic Street Light Control using RTC & LDR. ... We can control the street lights through manually, but it is a time taken and also time lagging chances are there so, the process was lagging ...
