Sep 18, 2017 · 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.
Mar 25, 2024 · Circuit Diagram and working of Automatic Street Light Controller Switch Using Relays and LDR. It automatically turns on and off street lights.
Insert first transistor Q1-BC547 (NPN) on breadboard (or general PCB) as shown in the circuit diagram 1. Connect another transistor Q2- BC547 (NPN) on the breadboard as in step 1. Connect wires across the emitter pin of both transistors and -Ve terminal of battery (lowest/bottom row of breadboard.)
The circuit diagram represents a simple automatic street light control system using transistors and a light-dependent resistor (LDR). Here is an explanation of its working: LDR: The LDR is a light-sensitive resistor that changes its resistance based on the intensity of light falling on it.
Automatic street light controller are devices or systems designed to control the operation of street lights based on predefined conditions. They play a crucial role in managing the energy consumption of street lighting, improving overall efficiency, and reducing costs.
Automatic street light control is used to control the street lights (Turn on and off based on the light). Here we make use of LDR (Light Dependent Resistor) and LED (Light Emitting diode) and arduino.
Oct 2, 2022 · Components Required & Circuit Diagram. The circuit is very simple and cheap as well. It can be implemented using following components: 1. L.D.R (Light Dependent Resistor) 2.
