The Sensirion SFA30 Formaldehyde Sensor 0-1000 ppb, Digital I2C is a highly accurate formaldehyde (HCHO) sensor module designed for HVAC, air purifiers, and indoor air quality monitoring. It detects low-level formaldehyde concentrations (0–1000 ppb) with low cross-sensitivity to ethanol and features integrated temperature and humidity compensation via a built-in RHT sensor. The module supports UART and I2C interfaces, boasts a 6-year lifespan with patented anti-dry technology, and operates reliably across varying indoor conditions.
Note: Refer to datasheet in the ATTACHMENTS section for more info. regd. the product.Features:
- Real-time detection of formaldehyde at low ppb levels
- Patented electrochemical sensor with anti-dry technology for extended lifespan
- Built-in Sensirion RHT sensor for temperature and humidity compensation
- Low false alarm rate due to minimal ethanol interference
- Dual interface support: UART and I2C for flexible integration
- Robust operation across 0–40 °C and 10–90% non-condensing humidity
- Factory-calibrated with lifetime calibration data
- Low power consumption suitable for portable and battery-powered devices
