We're doing some final optimization debugging and I think we have a good chance of completing our third sensor this month, the very nice performing SFA30-based formaldehyde sensor.
About SFA30 (https://sensirion.com/products/catalog/SFA30)
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™.
Since the sensor is very expensive, the projected pricing for the SFA-1 will be $47.90 (it's not over $50, great.), which will be one of our most expensive sensors to date. We will have a very nice discount for the first adventurers, but still, I hope you will be able to experience this very sensitive sensor with good immunity as we did. This will be our third air sensor, after the SCO2-1, PM25-1, we are now about to have the SFA-1, how exciting!
