Sensirion SFA30-D-T Digital Formaldehyde (HCHO) Gas Sensor Module, I²C/UART Output, Temperature & Humidity Compensated, 3.15~5.5 VDC
The Sensirion SFA30-D-T is a digital formaldehyde (HCHO) gas sensor module featuring integrated temperature and humidity compensation for high-accuracy indoor air quality monitoring. It provides a 0–1000 ppb measurement range via I²C or UART interfaces, making it compatible with microcontrollers like Arduino, Raspberry Pi, ESP32, and industrial PLCs.
Features
- Measures formaldehyde (HCHO) from 0 to 1000 ppb with 1 ppb resolution.
- Integrated Sensirion RHT sensor provides real-time temperature and humidity compensation.
- Dual digital interface: I²C and UART for flexible system integration.
- Patented anti-dry electrochemical sensor ensures a long service life of up to 6 years.
- Low cross-sensitivity to ethanol (<0.5%) for reduced false alarms.

The SFA30-D-T employs a patented electrochemical sensing principle for precise detection of formaldehyde concentrations at the parts-per-billion level. Its built-in RHT sensor continuously measures ambient temperature and relative humidity, applying real-time compensation algorithms to maintain accuracy across varying environmental conditions, crucial for reliable HVAC and air purifier control.
Designed for long-term stability, the module features anti-dry technology that preserves the sensor electrolyte, supporting a rated operational lifetime of six years. The factory-calibrated digital output via I²C or UART simplifies integration, eliminating the need for analog signal conditioning and providing direct, compensated concentration data to the host system.
