Most of the places have automatic street light which can sense the daytime and nighttime, and automatically turns on and off according the night and day. Here we are extending this project by adding one more constraint to turn on the light that is Street light will only glow if there is darkness and someone is passing through the street. The main objective of this project is to reduce the power consumption by glowing the Street light only when it is needed. In this project we are demonstrating the prototype of the Smart Street Light with 3 IR sensors, 1 LDR sensor and 3 LEDs - each representing one street light. We will also update the LDR and IR sensor data to the ThingSpeak CLOUD over the internet.      

Features:

• Automatic controlling of street lights.
• LDR based Day/night detection.
• IR sensor-based vehicle presence detection.
• Wireless data monitoring using Thingspeak cloud.
• To achieve this task using NodeMCU.

         

The major building blocks of this project are: -

• Adapter power supply.
• Three IR sensors.
• LDR(light dependent resistor).
• NodeMCU Microcontroller.
• High power LED as street light.

         

Software’s used:

1. Arduino ide studio compiler to write the program.
2.  Express SCH for Circuit design.
