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 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.

Content Evaluation Kit SEK-SFA30
- SFA30 formaldehyde sensor module
UART and I2C interface via 7-pin Molex Micro-Lock Plus connector
Supply voltage VDD: 3.3 or 5.0 V
Size: 46 x 24 x 5.5 mm3 - 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)

Evaluation Kit Quick Start
Start evaluating your SFA30 formaldehyde sensor in two simple steps:
1) Either download the SEK-ControlCenter viewer software (available for Windows, Linux and MacOS) or download one of our example drivers for your embedded platform (see links below)
2) Connect the SFA30 development board to your computer/embedded platform with the help of the adapter cables and start measuring
