The TVOC Gas Sensor detects volatile organic compounds in ambient air for integration into air treatment devices and air quality monitors. It is intended for developers who need to acquire gas concentration data using a microcontroller or single-board computer. In addition to TVOC, the sensor supports carbon dioxide and formaldehyde detection. Connection is via UART and requires a 5 V supply and a host interface compatible with 3.3 V logic. Development examples are available for Raspberry Pi, Raspberry Pi Pico, Arduino and ESP32.
