6-in-1 environmental sensor module enabling measurement of HCHO, TVOC, CO, IAQ, temperature, and humidity via UART communication. Provides high sensitivity thanks to electrochemical technology and compatibility with platforms such as Raspberry Pi, Arduino, and ESP32, making it suitable for air quality monitoring and IoT applications. Waveshare Environment X6 Sensor
Environmental sensor module enabling simultaneous measurement of formaldehyde (HCHO), total volatile organic compounds (TVOC), carbon monoxide (CO), indoor air quality (IAQ), temperature and humidity. Communication is handled via UART interface (9600 bps), allowing integration with platforms such as Raspberry Pi, Arduino, ESP32, and Raspberry Pi Pico.
The module uses solid polymer electrochemical technology (EC Sense) with a multi-electrode structure and solid electrolyte. This design provides high sensitivity and stable operation, eliminating common issues found in traditional gas sensors such as drift, sensor poisoning, and leakage.


The measurement range includes HCHO (0–1 ppm), TVOC (0–5 ppm), and CO (0–100 ppm), with resolution up to 0.001 ppm. The module enables fast detection of gas concentration changes and real-time environmental monitoring, making it suitable for air quality monitoring systems, building automation, automotive electronics, and IoT applications.
Compact size and low power consumption (approx. 6.5 mA) allow integration into portable and embedded systems. The module operates with a 5 V supply voltage and 3.3 V logic level.
