Sensor evaluation

The SFA30 is a digital formaldehyde sensor designed for easy integration into air purifiers, demand-controlled ventilation systems, or indoor air quality monitors.

Based on the electrochemical measurement principle, the SFA30 offers excellent performance with a uniquely low cross-sensitivity to other VOCs. The integrated humidity and temperature sensor provides accurate readings and enables a fully temperature/humidity compensated and factory calibrated formaldehyde concentration output in ppb. Selectable digital UART and I²C interface options, a standard electrical connector, and versatile mounting options make the integration easy. Relying on our experience in environmental sensing and a patented electrochemical cell with anti-dry technology, the SFA30 offers excellent long-term stability and 6 years service lifetime. On top of that, the SFA30 is compliant with the relevant healthy building standards RESET® and WELL Building Standard™.
