## Description

The Adafruit SEN6x Breakout lets you quickly connect a Sensirion SEN66 (or other SEN6x) environmental sensor node to any microcontroller or single-board computer via STEMMA QT / Qwiic — no soldering or breadboarding required. The adapter handles the SEN6x's special cable connection and power requirements automatically. A built-in 3.3 V regulator and level shifter allow the breakout to work with both 3.3 V and 5 V power and logic systems. Simply connect the SEN6x with a 6-pin JST GH cable, then plug a STEMMA QT cable into your development board's I2C port. Key Features SEN6x Compatible – Works with SEN66 and other SEN6x environmental sensor nodes JST GH Connector – 6-pin connector for direct plug-in to the SEN6x cable 3.3 V Regulator & Level Shifter – Compatible with both 3.3 V and 5 V systems STEMMA QT / Qwiic I2C – Solderless connection to any compatible development board Supported Measurements (via SEN6x) Temperature and humidity Volatile organic compounds (VOC index) Particulate matter: PM1, PM2.5, PM4, and PM10 NOx index (on supported SEN6x variants) Important: This adapter board does not include a SEN6x sensor or JST GH cable. Both must be purchased separately. Also Consider SEN54/SEN55 Adapter Breakout – Adapter for the previous-generation SEN5x sensor nodes Ideal For Comprehensive indoor air quality monitoring Particulate matter and VOC measurement stations Environmental research and data logging Smart building air quality systems Package Contents 1× Adafruit SEN6x Breakout for SEN66 Resources Sensirion Arduino Library (GitHub) Sensirion Raspberry Pi Python Library (GitHub)
