The PIR (Passive Infrared) sensor detects infrared light emitted by human bodies in motion. When motion is detected, the sensor outputs a high signal on the 'sig' pin.

Passive Infrared Sensor
Dos And Donts
Donts
Avoid Extreme Temperatures:
Do not expose the sensor to temperatures outside the range of -20°C to 85°C.,
Prevent Physical Obstruction:
Ensure the sensor's path is clear of any obstructions for accurate motion detection.,
Skip Library Installation:
Do not look for or install any additional Arduino libraries, as they are not required.
Dos
Check Voltage Compatibility:
Ensure the operating voltage is between 3V and 5V before connecting.,
Use Grove Interface:
Utilize the Grove interface for easy plug-and-play setup.,
Test Detection Range:
Verify the sensor's detection range (3.2m to 12m) and angle (100°) to optimize placement.
