## Description

The Adafruit STHS34PF80 is a compact IR presence and motion sensor that detects human and animal presence up to 4 metres away — without requiring a lens. Unlike traditional chunky PIR sensors with simple digital output, this sensor provides a full I2C interface with detailed readings on IR intensity, presence detection, movement, and temperature changes. The surface-mount sensor comes on a STEMMA QT breakout with a 3.3V regulator and level shifting, making it compatible with both 3.3V and 5V logic. STEMMA QT / Qwiic connectors on each side enable solderless I2C daisy-chaining. Key Features STHS34PF80 IR Sensor – Detects presence, motion, and temperature changes Up to 4 m Range – No lens required, easy to fit in small enclosures I2C Interface – Detailed IR readings beyond simple on/off detection STEMMA QT / Qwiic – Solderless I2C connectors for easy daisy-chaining 3.3V Regulator + Level Shifting – Compatible with 3V and 5V logic Compact Form Factor – Much smaller than traditional PIR sensors Ideal For Room occupancy and presence detection Motion-activated lighting and displays Smart home automation Compact security and monitoring systems Package Contents 1× STHS34PF80 breakout board (assembled and tested) Note: STEMMA QT cable not included.
