S88

The S88 is a refresh of our popular S8 platform that defined modern sensor pin configurations. The same form factor, the same cost efficiency, designed for mass production and it of course come with the same pin configuration.

Defining attributes

  • Compliant with ANSI/ASHRAE Standard 62.1-2022
  • Compliant with RESET grade B
  • Compliant with WELL Building Standard® (WELL v2™)
  • Compliant with California Energy Code
  • Cost efficient
  • Low Power consumption
  • High Precision
  • Mass Production
  • Self-correcting

What we have done with the S88 is refresh its internals, ensuring a long period of support and availability moving forward. We’ve also made sure it meets the latest standards, including ASHRAE 62.1-2022 addendum ab. The appearance and I/O of the sensor remains identical, making sure that, should you choose, transitioning from the S8 to the S88 is as smooth as possible.

The S88 punches well above its weight in terms of both cost and size, and its ease of integration makes it an easy recommendation for a large variety of use cases.

We currently offer the S88 as a version optimized for low power applications and one for residential applications.
