Features

• The product information found on this page currently pertains to Revision B of this product, which provides many updates and new features from Revision A. PIR (Passive Infra-Red) sensor module. The PIR (Passive Infra-Red) Sensor is a pyroelectric device that 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. This logic signal can be read by a microcontroller or used to drive an external load. Detect a person up to 10 m away, or up to 5 m in reduced sensitivity mode Jumper selects normal operation or reduced sensitivity Supply current up to 12 mA @ +3 V, 23mA @ +5 V Onboard LEDs light up the lens for fast visual feedback when movement is detected Mounting holes for 2-56 sized screws 3-pin SIP header ready for breadboard or through-hole projects Small size makes it easy to conceal Easy interface to any microcontroller Power requirement: +3 to +6 Vdc, 130 μA idle, 23 mA active (no load) Communication: Single-bit high/low output Dimensions: 35.8 x 25.4 x 20.3 mm Operating temperature range: 0 to +50°C
