SenseAir K33 NDIR CO2 Sensor

规格

Product Introduction

The CO Engine ICB-F is a sensor module designed for bio applications with a measurement range of 0 to 2 vol% CO2. It is built on the CO Engine K33 platform, which is a low power OEM module intended for built-in applications in a host apparatus or as a standalone CO2 transmitter/switch module. The sensor has the same dimensions and attachment points as K30 platform based sensors.

Features

  • Measurement range 0 to 2 vol% CO2
  • Low power OEM module design
  • Compatible with K30 platform dimensions and attachment points
  • Available in tube in/out modification with different orientations in steps of 120 degrees
  • Multiple communication interfaces including UART and I2C
  • Digital and analog output options
  • Digital switch inputs for calibration forcing
  • ABC algorithm support for automatic baseline correction

Applications

  • Bio applications requiring CO2 measurement
  • Built-in applications in host apparatus
  • Standalone CO2 transmitter/switch modules
  • Environmental monitoring systems
  • Indoor air quality monitoring
