Sensirion SFA40 Miniature Formaldehyde Sensors
Sensirion SFA40 Miniature Formaldehyde Sensors builds on the market success of its predecessor, the SFA30, offering ultra-high selectivity to formaldehyde and a long lifetime. It features unprecedented low power consumption and top performance, all in a miniature form factor. Engineered in Switzerland, it is designed for easy integration into air purifiers, indoor air quality monitors, and air conditioners. All Sensirion SFA40 sensors feature a digital I2C interface and are calibrated for accuracy.
