Passive Infrared Motion Sensor
The PIR Sensor detects motion by measuring changes in the infrared (heat) levels emitted by surrounding objects. When motion is detected the PIR sensor outputs a high signal on its output pin.
Key features:
- Typically detects a person up to approximately 30 feet away, or up to 15 feet away in reduced sensitivity mode
- Jumper selects normal operation or reduced sensitivity
- Approximately 90 degree field of view
Onboard LEDs light up the lens for fast visual feedback when movement is detected - Mounting holes for 2-56 sized screws provide easy integration in permanent applications
- 3-pin SIP package perfect for breadboard-friendly projects
- Easy communication with any microcontroller
- Small size makes it easy to conceal
