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. 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 6 years service lifetime.

USB-UART cable
(7-pin, marked with an orange sleeve) to connect the SFA30 development board directly to a USB port, e.g. on a PC
Jumper wire set (7-pin Micro-Lock Plus cable set) to connect the SFA30 development board to embedded testing platforms like Arduino or Raspberry Pi. A 10-pin 0.1’’ pitch gender changer is also provided.
Cable configuration:
- Red cable = VDD
- Black cable = GND
- Green cable = SDA (I2C) or RX (UART)
- Yellow cable = SCL (I2C) or TX (UART)
- Blue cable = SEL (Interface select - Connect to GND for I2C, connect to VDD or leave open to select UART)
- Purple cable = NC (do not connect)
- Grey cable = NC (do not connect)
