Automatic Room Light Controller - Coggle Diagram
Automatic Room Light Controller
Main components:
Arduino/other microcontroller
2 × IR sensors
Relay module
LED/bulb
Power supply
Connecting wires
We chose the Automatic Room Light Controller experiment because:
It prevents lights from being left ON when the room is empty.
It provides a simple and practical real-world solution.
It helps us learn about IR sensors, microcontrollers, and automation.
It can be used in classrooms, laboratories, offices, and homes.
It supports energy conservation and smart technology.
It helps save electricity by switching lights ON/OFF automatically.
It reduces human effort and avoids manual switching.
Problems in Existing Room Lighting System
Lights are often left ON when nobody is in the room.
Manual switching is inconvenient for users.
Unnecessary lighting causes electricity wastage.
Users may forget to switch OFF the lights while leaving.
It is difficult to monitor room occupancy manually.
Continuous unnecessary usage can increase electricity bills.
In classrooms and laboratories, lights may remain ON during breaks or empty periods.
Manual control does not provide an automatic and energy-efficient solution.
