TVOC Gas Sensor Expansion Board

Total Volatile Organic Compounds Sensor

Can be easily integrated into air handling equipment or air quality monitors

Product Features

TVOC Sensor is an efficient tool for assessing air quality, specially designed to accurately measure TVOC (Total Volatile Organic Compound) gas concentration in the environment. It has excellent adaptability and scalability and can be customized according to the specific needs of users.

Can measure TVOC (total volatile organic compounds), CO₂ (carbon dioxide) and CH₂O (formaldehyde) in the environment

Support UART communication

High sensitivity, low power consumption, long service life, compact size

Provide complete supporting manuals (Raspberry Pi / Pico / Arduino / ESP32 example programs and user manuals, etc.)
