Background
Minimizing energy usage.
Simple way to turn on the fan.
More comfort activity.
DescriptionThis project using PIR as its sensor, the main components are fan and LED as the indicator. This project were designed to bathroom used. If motion are detected with PIR sensor, the fan and LED will automatically turn on.

Tools and Materials
PIR sensor The PIR sensor itself has two slots in it, each slot is made of a special material that is sensitive to IR. The lens used here is not really doing much and so we see that the two slots can 'see' out past some distance (basically the sensitivity of the sensor).

Tools and Materials
ResistorA resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses

Coding
Procedure 1Prepare all the tools and materials.
2Make a circuit from the components to PCB.
3Connect the circuit to the arduino and upload a program from PC .
4Check the project, is it work or not.
5Make a prototype building of a project.
6Combine the wiring project with the
prototype building.

Analysis
Motion are detected
The fan and LED automatically turn on.
There’s no motion
The fan and LED did not work.
Conclusion
• PIR sensor and Arduino make the activity easier.• PIR sensor can only detect a human or animal.
