S8 Alarm 5%

Small components and advanced design for control- and alarm applications. The sensor can be integrated into a wide range of different alarm applications where you want to detect CO₂, such as leakage detection.

Defining attributes

  • Miniature size
  • Easy integration
  • Individually calibrated
  • Maintenance free
  • Long term stability

More than 25 years of experience of research and development within the field of infrared gas sensing has now brought us the smallest CO2 sensor with NDIR-technique in the world: the S8 5%. The new sensor has excellent performance, such as high accuracy and low power consumption. S8 5% is designed for high volume production with full traceability by sensor serial number on all manufacturing processes and key components. Every sensor is individually calibrated and is provided with a UART digital interface. The sensor is maintenance-free and has an estimated life time of more than 15 years.

S8 5% is a module that is designed for simple integration into products. S8 5% can be used in a wide range of applications such as in ventilation control to improve energy savings and to assure a good indoor climate. Other fields of use are personal safety and measurements to increase process yield and to increase economic value in bio-related processes.
