S8

More than 30 years experience of research and development within the field of infrared gas sensing has brought us our smallest NDIR CO2 sensor. The sensor has excellent performance such as high accuracy and low power consumption.

Defining attributes

Low power consumption
Miniature size
Individually calibrated
Maintenance free
Long term stability

Senseair S8 sensors are designed for mass production with full traceability by sensor serial number on all manufacturing processes and key components. Every sensor is individually calibrated and is provided with UART digital interface. The sensor is maintenance-free and has an estimated life time of more than 15 years.

It comes in a few different variations, the residential variation intended for residential IAQ applications, a commercial variation for stricter compliances and a low power version for applications with power limitations.
