      • Formaldehyde Sensor SFA30

        Formaldehyde Sensing Made Easy

        The SFA30 is Sensirion’s new digital formaldehyde sensor designed for easy integration into air purifiers, demand-controlled ventilation systems, or indoor air quality monitors. Based on Sensirion’s electrochemical technology, the SFA30 offers excellent formaldehyde sensing performance with a uniquely low cross-sensitivity to other VOCs. The sensor module’s on-board SHT sensor provides accurate humidity and temperature readings and enables a fully temperature/humidity compensated and factory calibrated formaldehyde concentration output in ppb.
