The S8 LP sensor has excellent performance, such as high accuracy and low power consumption. S8 LP 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 lifetime of more than 15 years.
  • Low power consumption
  • Miniature size
  • Individually calibrated
  • Maintenance-free
  • Long term stability
Senseair S8 LP is a miniature, low-power CO2 sensor module developed for applications where both energy consumption and accuracy are critical factors. With an average power consumption of 18 mA and an accuracy of ± 40 ppm and ± 3% of reading, the S8 LP is the natural choice for developers who demand the best of two worlds. S8 LP is a module that is designed for simple integration into products. S8 LP 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.
