1.Introduction

3. 2.Components used
1. PIR sensor - to sense motion and provide signal to Arduino
2. Arduino UNO - take signal from PIR sensor and activate the
relay module
3. 5V Relay Module (Relay Board) - allow a low power control
voltage
4. LED - lighting tool

4. 5.100Ω Resistor (1/4 Watt) - to limit current flow
6.Connecting Wires - for transferring the current supply
7. Breadboard - make electrical connections between
components
8. Power Supply - for providing electric current to run the
things
to be continued...

9. 5.3 Final output

10. • Lamp will turn on if any moment detected by PIR sensor.
• Lamp will remain off if there is no any moment detected
by PIR sensor.
6. Results

11. A few applications of the
Automatic Room Lights
concept. Some of them are: 1.
Garage Lights
2. Bathroom Lights
3. Hand Dryers
4. Toilet Flushers
5. Security Lightsroom
7. Applications

12. 8.Cost estimation
Components Cost
Arduino UNO ₹ 550/-
PIR sensor ₹55 - ₹65/-
Single-Channel Relay Module ₹45 - ₹50/-
Other expenses (cost of led, resistor,
connecting wire, power supply)
₹ 30/-
Total ₹₹ 690/-

13. • In this project, we saw the where the lights in the room will automatically
turn ON and OFF by detecting the presence of a human.
• Means when there is need only then and there light will be present.
• Hence minimise the wastage of electrical power, and saving the energy.
