Arduino Light Sensor Circuit using LDR -

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

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.

Automatic Room Lights using PIR Sensor and Relay: Circuit Diagram

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.

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.

Automatic Street Light - Electronic Projects and Circuit made ...

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.

Auotmatic Street Lights Control Using LDR and Arduino

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.

Simple Automatic Street Light Circuit Diagram with LDR

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:
