Adafruit SEN54 or SEN55 Adapter Breakout - STEMMA QT / Qwiic

Quickly integrate the Sensirion SEN54 or SEN55 environmental sensor node into your projects with this Adafruit SEN54 or SEN55 Adapter Breakout. This breakout simplifies connectivity by providing a JST GH-compatible connector to plug a 6-pin GH cable directly between your SEN sensor and the adapter. It features a small boost converter generating 5V at 100mA to power the fan and electronics on the SEN5x, even when using 3V power and logic.

The breakout allows easy connection to your Metro, Feather, QT Py, Raspberry Pi, and more via STEMMA QT I2C connectors for seamless integration. Use Sensirion's Arduino or Raspberry Pi Python libraries to read data such as temperature, humidity, VOC, Particulate Matter (PM1/PM2.5/PM4/PM10), and NOx (SEN55 only).

Important: This product does not include the JST GH-compatible cable or the SEN5x sensor. These can be purchased separately.
