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
