SparkFun Qwiic Low Power PIR Sensor Module, 1µA Standby
Ultra-low power 1µA PIR motion sensor with Qwiic connectivity. Ideal for battery-powered IoT and smart home projects.
The SparkFun Qwiic Low Power PIR Sensor Module is a passive infrared motion detection solution, featuring an ultra-low 1µA standby current draw that makes it perfect for battery-powered IoT projects. This compact module combines Panasonic's high-performance EKM-series PIR sensor with an ATtiny84 microcontroller and SparkFun's convenient Qwiic connector system for plug-and-play prototyping.
Key features include digital output across 32 detection zones, a 5-metre sensing range, and a wide 90°×90° (±45°) detection area. The module's clever design includes dual Qwiic connectors for easy daisy-chaining in I²C networks, while maintaining a minimal footprint with its small 10.9×10.4mm lens dimensions.
Technical Highlights
- Energy Efficient: Consumes just 1µA in standby mode for extended battery life
- Flexible Configuration: Programmable ATtiny84 MCU with accessible programming header
