AGS10 TVOC Air Quality Sensor Breakout Board, Calibrated I²C Gas Sensor, 3.3V & 5V, Qwiic/STEMMA QT compatible

This breakout board is based on the fully calibrated AGS10 TVOC sensor and is ideal for monitoring indoor air quality in smart home, IoT, and maker projects. The sensor is factory-calibrated and tested and provides TVOC readings in ppb.

The board is optimized for practical use with common microcontrollers: an integrated 3V voltage regulator powers the sensor within its specified operating range, while the I²C level shifter enables safe communication with both 3.3V and 5V systems (e.g. Arduino, ESP32, Raspberry Pi, RP2040).

Thanks to the integrated Qwiic / STEMMA QT compatible JST-SH connector, quick, solder-free connections are possible. In addition, classic pins/solder pads are available for maximum flexibility in prototyping and permanent installations.

Arduino example code is available in our GitHub repository.

Technical Specifications

Notes

• After power-up, the sensor requires a short warm-up time for stable measurements.
• For reliable data, the measurement interval should not be set too short.
