    Regular price $109.00

    POs or wholesale quantity discounts click here

    The ExplorIR®-M  (formerly known as MinIR) CO2 sensor 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 5% CO2
    • MX Board includes Barometric Pressure, Temperature and % Relative Humidity Sensors
    • Durable, low power consumption, and miniature format
    • Reliable to measure CO2 levels in rough, harsh environments
    • MX Board adds UART, RS485, and RS485 Modbus
    • Analog Output, Voltage PWM
    • Ideal for battery powered applications
    • Easy Integration; Compact & Low Power


    CM-40331 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-40330 MX Board – Same functionality as the development kit without USB cable or software.

    GC-0024 Sensor Only – for integration into high-volume OEM products.
