Asahi Kasei Subsidiary Pitches New Sensing Module

Senseair, a subsidiary of Asahi Kasei Microdevices Corporation (AKM), has announced the launch of the Senseair S88. Accordingly, the S88 is an accurate, compact, and maintenance-free CO2 sensing module ideal for indoor air quality monitoring. Moreover, it is also suitable for 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). Furthermore, the ABC algorithm constantly tracks measurement deviations, enhancing long-term accuracy and reliability without the need for 3rd party interaction with the sensor.

Suits Industrial Use

The S88 is a refresh of the company’s popular S8 platform. Particularly, it defines modern sensor pin configurations. The same form factor, the same cost efficiency, designed for mass production. Of course, it comes with the same pin configuration.

The S88’s compact form factor (8.7 x 33.9 x 19.8mm), 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. Thus, eliminating the need for costly re-design efforts.

The S88 has high precision across a wide measurement range (400 ppm to 10,000 ppm), making it suitable for various applications. It also features an operating temperature range of <50℃ and a humidity range of <85% RH.

Moreover, 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), RESET grade B, and WELL Building Standard® (WELL v2™).

Senseair will begin mass production of the S88 in April of 2024. More information about the S88 is available at
