The ExplorIR®-M CO2 Sensor (formerly known as MinIR) brings solid state electronics to NDIR CO2 sensors.

ExplorIR®-M uses LEDs to deliver ultra-low power and rugged/vibration-resistant performance. Combined with the MX board, it provides full-featured capability for industrial, scientific, engineering or OEM applications.


  • NDIR LED Sensor Measures up to 100% CO2
  • MX Board includes Barometric Pressure, Temperature and % Relative Humidity Sensors
  • Robust, low power, in miniature format
  • Best-in-class power consumption, lifetime durability
  • Built to reliably measure CO2 levels in harsh environments
  • MX Board adds RS485 Industry-standard Interface
  • Easy Integration; Compact & Low Power


CM-40831 Development Kit – Easy to use, simply plug the MX Board into your PC via USB. Use our free GasLab® software to measure and graph carbon dioxide, barometric pressure, temperature, and % relative humidity. Includes on-board memory for data logging.

CM-40830 MX Board – Same functionality as the development kit without USB cable or software.

GC-0025 Sensor Only – for integration into high-volume OEM products.
