COZIR Ultra Low Power CO2 Module

The COZIR is a CO2 module for OEM applications that represents a breakthrough in low power gas detection making it ideal for battery powered, energy harvesting or wireless applications with tight energy budgets requiring long operating life. This Infrared LED based sensor offers a number of distinctive features over conventional CO2 sensors. Key features of the COZIR-A CO2 sensor include:

  • Continuous power consumption of 3.5 mW.
  • With reasonable duty cycling (e.g. 15 min) battery life can be extended to 5+ years or more on a single AA battery.
  • Measurement ranges of 0-2000 ppm, 0-5000 ppm and 0-1% (10,000 ppm).
  • Instant warm up time.
  • Shock and vibration resistant.
  • Built in auto calibration feature that can be customized to the application.
  • Options for on-board temperature and humidity measurement and extended temperature operating range of -13 to 131F (-25 to 55C).
  • Serial output and optional 0.1 to 3.3 V output.
  • Simple, closed contact initiation of ambient or zero calibration.
  • Runs cool, there is no heat generated that can interfere with temperature or humidity measurements.
  • Other models (COZIR-A) can measure to 2%, 5%, 20%, 60% and 100%.

The MISIR is a very cost effective, low power LED based sensor similar to the COZIR-A but with a rectangular footprint and slightly higher energy consumption of 20 mA under continuous operation. Otherwise the MISIR has the same operating features as the COZIR-A.

In order to allow the integration of the product with already designed products, the MISIR is available with similar footprint and pin outs to two of the major CO2 module manufacturers allowing for easy product substitution or second sourcing.

The PC Software allows users to trend the output from all Gas Sensing Solutions (GSS) products including the COZIR-A, COZIR-W, MISIR, and SPRINTIR modules. It also supports calibration of the sensor and insertion of serial commands to configure various aspects of the sensor.

The Windows compatible program is free. A USB cable is available that will connect the sensor to a PC and that provides a serial interface and power to the sensor. To order the cable from AirTest specify model COZIR-Kit and specify the GSS module you will be using it with.
