PIR Sensor

Detect motion by measuring heat signals.

• 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
• 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

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.
