A motion sensor light circuit is a circuit in which a light turns on when motion is detected. With a PIR motion sensor integrated with an arduino, we can detect movement and program the arduino to turn a light on for a certain period of time once this motion is detected.
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.
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 automaticall...
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.

The heart of this circuit is a LDR (Light Depended Resistor) which is connected as a potential divider with a 56K resistor. The drop across LDR is used for switching the transistor. Solar led street lighting systems are the advanced versions of this ordinary automatic street light controller. Solar table lamp circuit for your home; Remote ...
Transistor (those 3 legged thingies): Used as an amplifier, automatic switch etc., (in this project we are using it as an automatic switch). LDR (Light Dependent Resistors) also known as cadmium cell: LDRs or Light Dependent Resistors are very useful, especially in light/dark sensor circuits. Normally the resistance of an LDR is very high ...
The main relatively simple but with the development of aim of the project is Automatic street power saving urbanization, the number of streets increases rapidly system with LDR and motion sensor; this is to save as a result of which the number of street light has also the power.
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.
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 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.
Hence, we can utilize the light sensor circuit for automatic switch OFF the loads based on daylight's intensity by employing a light sensor. This article discusses in brief about what is a light dependent resistor, how to make a light dependent resistor circuit and its applications. What is a Light Dependent Resistor?

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.
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.
When there is low amount of light the light automatically glows and when there is sufficient amount of light it automatically turns off the light. Here based on our room condition the threshold value we took is 100 for the LDR sensor.
So to flow current we have to apply have current on base for flow current, so we off the light. Resistance of LDR is low current will flow it and apply on base. When current is passes from base current will also flow have transistor then passes form led. LED is on, again when you on the light led off. Dome Video of automatic street light:
Circuit Diagram and working of Automatic Street Light Controller Switch Using Relays and LDR. It automatically turns on and off street lights.
These Light Detectors or Sensors can detect different types of light like visible light, ultraviolet light, infrared light etc. In this project, we have designed a simple Light Detector using LDR. When the light falls on the LDR, the light stays off and when the light stops falling on LDR, the LED glows.
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.
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.
