# Adafruit SEN6x Breakout

## Overview

![breakout attached to sensor and feather tft showing data](https://cdn-learn.adafruit.com/assets/assets/000/137/034/medium800/sensors_6331-06.jpg?1747859575 )

Warning: Please note: this board does NOT come with a JST GH-compatible cable NOR a SEN6x sensor! You can [pick up the cable here](https://www.adafruit.com/product/5754), and a [SEN6x from DigiKey](https://www.digikey.com/en/product-highlight/s/sensirion/environmental-sensor-node-sen6x).

Now you can quickly integrate the [Sensirion SEN6x environmental sensor node](https://blog.adafruit.com/2025/05/08/eye-on-npi-sensirion-sen66-environmental-sensor-node-eyeonnpi-digikey-digikey-sensirion-adafruit/) into your microcontroller or microcomputer project, with no soldering or fiddly breadboarding, thanks to the **Adafruit SEN6x Adapter Breakout** (for SEN66 and friends). We covered the awesome [Sensirion SEN66 environmental sensor nodes on EYE ON NPI](https://blog.adafruit.com/2025/05/08/eye-on-npi-sensirion-sen66-environmental-sensor-node-eyeonnpi-digikey-digikey-sensirion-adafruit/) a while ago; it's an awesome all-in-one air quality sensor, but it has the annoyance that it requires 3V power/logic, and it has a special cable connection.

This adapter breakout will make an instant friendship with all SEN6x boards, thanks to a JST GH-compatible connector in the middle which you can plug a [6-pin GH cable](https://www.adafruit.com/product/5754) directly between your SEN6x and this adapter. In the middle is a clean 3.3V regulator and level shifter, so you can use this module whether you're using 3.3V or 5V power and logic. [Then you can use any ol' STEMMA QT cable](https://www.adafruit.com/product/4210) to plug into your Metro, Feather, QT Py, Raspberry Pi, etc, etc. I2C port.

Once you've got it plugged together, you can run Sensirion's [Arduino library](https://github.com/Sensirion/arduino-i2c-sen66) or [Raspberry Pi Python library](https://github.com/Sensirion/raspberry-pi-i2c-sen66) to read temperature, humidity, VOC, Particulate Matter PM1 / PM2.5 / PM4, and PM10. (NOx reading is also available on the SEN55).

 **Please note: this board does NOT come with a JST GH-compatible cable NOR a SEN6x sensor!** You [can pick up the cable here](https://www.adafruit.com/product/5754), and [a SEN6x from DigiKey](https://www.digikey.com/en/product-highlight/s/sensirion/environmental-sensor-node-sen6x).
