PIR Sensor (Rev B)

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.

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:

• Detection range up to 15 ft. away on short setting, up to 30 ft. away on long setting.
• 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.
