Total Volatile Organic Compounds Sensor
for easy integration into air treatment devices and air quality monitors

The TVOC Sensor is an efficient tool for air quality assessment, specifically designed for precise measurement of TVOC (Total Volatile Organic Compounds) gas concentration in the environment. Features excellent adaptability and expandability, and can be customized according to the specific needs of users.
- Capable of detecting TVOC (Total Volatile Organic Compounds), CO₂ (Carbon Dioxide), and CH₂O (Formaldehyde) concentrations in the environment
- Supports UART communication
- High sensitivity, low power consumption, long lifespan, compact size
- Comes with online development resources and manual (examples for Raspberry Pi / Raspberry Pi Pico / Arduino / ESP32)
