Aim
Problem statement
Most of the street lights are manually operated. When not operated properly, the street lights emit light during day time. Even if properly operated, the street lights emit light with full brightness all the time, even when there is no vehicle or person. This results in wastage of electricity. In order to solve this issue, we bring in an automatic street light system that turns on and off according to the amount of light outside. It emits the light with 30% brightness and emits full brightness if it detects any vehicle or person.
Material used
Input: Light Sensor
Brain: TinkerSpace Sensor Board
Output: LED Lamp
Battery: 5V Lithium-ion rechargeable battery
Component description
Light sensor
LED Lamp
The function of the LED lamp is to emit the light.
TinkerSpace Sensor Board
TinkerSpace board acts as brain of this project, its function is to monitor Light Sensors and control the Street light.
Battery
5V Lithium-Ion battery is used to power-up this project
Working description
Case – 1: During day time, the light sensor (input) turns ON by sensing the sunlight and sends the signal 1 to the TinkerSpace sensor board (brain). The sensor board turns OFF the LED lamp (output).
Case – 2: During night time, the light sensor does not sense the sunlight and it turns OFF. Hence the sensor board turns ON the LED lamp.
Light sensor ON —> LED lamp OFF
Light sensor OFF —> LED lamp ON
Circuit Design (DesignSpace)
Step 1: Connect LIGHT SENSOR to input
Step 2: Connect LED LAMP to output 1
Step 3: Select REVERSE MODE (R) in Sensor board
Step 4: Connect supply and test project.
