SFA30 Formaldehyde Sensor Module

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 full 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 Sensirion’s experience in environmental sensing and a patented electrochemical cell with anti-dry technology, the SFA30 offers excellent long-term stability and six-year service life.
