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 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 Application Ideas: Motion-activted nightlight Alarm system Animated holiday props Details: Source current up to 12 mA @ 3V, 23 mA @ 5V Voltage requirements: 3 to 6 VDC Current requirements: 130 uA idle, 3 mA active (no load) Communication: Single bit high/low output Dimensions: 1.41 x 1.0 x 0.8 in (3.6 x 2.5 x 2.0 cm) Operating temp range: 32 to 122 °F (0 to 50 °C)
