SparkFun Qwiic PIR Sensor Module, 170μA

The SparkFun Qwiic PIR Sensor Module is a low-profile passive infrared (PIR) sensor designed for motion detection in close proximity applications. Featuring Panasonic's EKM-series PIR sensor paired with an ATTiny84 microcontroller, this module provides reliable motion sensing with minimal power consumption, making it ideal for continuously powered applications.

Key features include digital output across 32 detection zones, a 5-metre range, and a 90°x90° (±45°) detection area. With dual Qwiic connectors for easy I2C integration, this sensor simplifies prototyping and system development. The module also includes a 2x3 header on the back for reprogramming the ATTiny84 MCU, offering flexibility for custom applications.
