Revision History

The information that follows contains revision history for the PIR documentation.

V 2.0: PIR Sensor Rev A

Both revisions of this sensor use the same Fresnel lens, and basic functionality remains the same

between the two (for example you can use the same test programs). However, there were a number of

improvements and updates made to Revision B, and if using Revision A in your project the following

information should be noted and used.

Features

 Detection range up to 20 feet away

 Single bit output

 Jumper selects single or continuous trigger output mode

 3-pin SIP header ready for breadboard or through-hole project

 Small size makes it easy to conceal

 Compatible with BASIC Stamp, Propeller, and many other microcontrollers

Key Specifications

 Power Requirements: 3.3 to 5 VDC; >3 mA (may vary)

 Communication: Single bit high/low output

 Operating temperature: 32 to 122 °F (0 to 50 °C)

 Dimensions: 1.27 x 0.96 x 1.0 in (32.2 x 24.3 x 25.4 mm)

Key Differences

 Jumper setting controls triggering and not distance

 Driving an external load requires a transistor or MOSFET

 Detection range up to 20 ft away

Pin Definitions and Ratings

Pin Name Function

- GND Ground: 0 V

+ Vin Supply Voltage: 3 to 6 VDC

OUT Output Connect to I/O pin set to INPUT mode (or transistor/MOSFET).

Jumper Settings

Symbol Description

Output remains HIGH when sensor is retriggered repeatedly. Output is LOW when idle (not

triggered).

Output goes HIGH then LOW when triggered. Continues motion results in repeated

HIGH/LOW pulses. Output is LOW when idle.

V 2.1: The explanation of the sensitivity jumper setting have been updated throughout, and the Range

section, including a temperature vs. range graph, were added.

V 2.1: Added information for load current to Features and Specifications.
