Adafruit STHS34PF80 IR Presence / Motion Sensor - STEMMA QT / Qwiic

We stock many low cost "Passive IR" Presence / Motion sensors, popular for detecting motion from humanoids and pets 5 to 20 feet away. The Adafruit STHS34PF80 IR Presence / Motion Sensor is a deluxe PIR sensor version that detects presence up to 4 meters away without requiring a lens, making it ideal for small enclosures.

This sensor comes with a full I2C interface to provide detailed info about IR detected, presence, movement, or temperature changes. It features a surface-mount sensor on a PCB with a 3.3V regulator and level shifter compatible with 3V or 5V logic microcontrollers or SBCs.

The custom PCB uses the STEMMA QT form factor with STEMMA QT connectors compatible with SparkFun Qwiic I2C connectors for solderless connection and chaining.
