First start form battery. Resistance of LDR = 180 k under minimum light for which LED should be OFF (if we further reduced the light, resistance will increase, then "LED" should turn ON and "transistor 1" should turns OFF). What is an Automatic Street light ? Thus, when there is no light, the resistance of LDR . LDR output is connected as input to comparator. This sensor is used to detect the light intensity so if there's sun light in the surroundings then it simply turn OFF the street light and if there's no sun light then it turns ON the street light and that's how Automatic Street Light works. The heart of the circuit is a very common operation amplifier IC 741 (IC 1) and is used herein inverting mode. This project check the amount of light. Hardware Setup: The HC-SR04 Ultrasonic Sensor is at the center of the vehicle. Abstract- Automatic street light control system is used in modern world for energy savings by using Light dependent Resistor (LDR).Nowadays the human has not enough time, and he/she is unable to find time even to switch the lights on or off. The LDR's resistance is usually in the M range when it is dark.
