Senseair releases new module, S88, for advanced CO2 monitoring



Senseair, a subsidiary of Asahi Kasei Microdevices Corporation (AKM), proudly announces the launch of the Senseair S88.  The S88 is an accurate, compact, and maintenance-free CO2 sensing module that is ideal for indoor air quality monitoring and building automation control across a variety of environments.

The S88 uses non-dispersive infrared (NDIR) technology for CO2 detection and features Senseair’s proprietary Automatic Baseline Correction (ABC).  The ABC algorithm constantly tracks measurement deviations, enhancing long-term accuracy and reliability without the need for 3rd party interaction with the sensor.  

The S88’s compact form factor, 15+ year life expectancy, and maintenance-free approach make it a good fit for industrial environments where space and accessibility can present a challenge.  Similarly, the S88 is pin-compatible with other popular Senseair products and some competing solutions, eliminating the need for costly re-design efforts.

The S88 module’s high accuracy aligns with the latest standards (ANSI/ASHRAE Standard 62.1-2022 Addendum ab) set by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).

Senseair will begin mass production of the S88 in April of 2024.
