The PIR Sensor detects motion by measuring changes in the infrared (heat) levels emitted by surrounding objects. When motion is detected a LED lights up the lens dome as a visual signal, and the module also outputs a high signal on its output pin.
NOTE: The product information found on this page currently pertains to Revision B of this product, which provides many updates and features from Revision A. Some of these include:
- Longer detection range, selectable by onboard jumper
- Wider supply voltage, from 3 to 6 VDC
- Higher output current provides for direct control of an external load
- Mounting holes included for permanent projects
- All parts SMT
Key Features:
- Typically detects a person up to approximately 30 ft away, or up to 15 ft away in reduced sensitivity mode
- Jumper selects normal operation or reduced sensitivity
- Approximately 90 degree field of view
- LEDs light up the dome for visual signal of sensor activation
- 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
