Figure 1. Transparent block diagram of Automatic Street Lighting System. The street lamp period, water detection, light detection and presence of vehicles are the four processes managed and controller by the microcontroller based on the input from the laser sensor, dark sensor and water sensor.
Circuit Diagram and Explanation: Below is the circuit diagram of this Light sensing Street Light: In this project, we have used an LDR (Light Dependent Resistor) which is responsible for detecting light and darkness. The resistance of LDR increases in darkness and reduces in presence of light.
work is to describe the Intelligent Street Lighting (ISL) system, a first approach to accomplish the demand for flexible public lighting systems. GSM based smart street light monitoring and control system , it is an automated system designed to increase the efficiency and accuracy of an industry
26 Figure 2.1: Simplified block diagram of smart street lamp monitoring system In the LDR module, it consists of two LDR. One of the LDR is install on top of the street lamp for the checking the day/night status condition. Another LDR is place under the street lamp to …
The street lights will turn on until the PIR sensor does not sense any movement within 10 seconds, therefore street lights will be turned off. When LDR sensor senses the intensity of light from the sun, the system will turn off both street lights and PIR sensor. Lastly, the system will loop to the initial condition.
Working of Automatic Street Light circuit. One end of the LDR is connected to the base of a BC 187 transistor. At night, the drop is very high (> 0.6V) and it is sufficient to turn on the transistor. When the first transistor is ON next one will also turn ON. Thus the relay coil energizes and the bulb will glow.
Code for light sensor and street light control using Arduino is given below : int Adc_channel = A0; // select the input pin for the potentiometer. int output_pin = 13; // select the pin for the LED. int light_value = 0; // variable to store the value coming from the sensor. void setup()
In 2014 Instruments Universal become the vendor of General Electric for Automation and energy conservation Street light and Lamp monitoring and control system. Instruments Universal was India's first company to implement GSM/GPRS based street light monitoring and control system in the field.
