ExplorIR®-M 20% CO2 Sensor
The ExplorIR®-M 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 the full-featured capability for industrial, scientific, engineering, or OEM applications.
- NDIR LED Sensor measures up to 20% CO2
- Includes barometric pressure, % relative humidity, temperature sensors
- Sensor life expectancy > 15 years
- Serial UART, analog output
- Best-in-class power consumption, durability
- Built to reliably measure CO2 levels in harsh environments
- Easy integration: Compact & low power
CM-40531 Development Kit – Easy to use, simply plug the MX Board into your PC via the included serial UART to USB cable. Use our free GasLab® software to measure and graph carbon dioxide, barometric pressure, temperature, and % relative humidity.
CM-40530 MX Board – Same functionality as the development kit without USB cable or software.
GC-0026 Sensor Only – for integration into high-volume OEM products.

Free Easy-to-use GasLab® Software
This device uses GasLab® software for setup, calibration, data logging, and real-time data analysis. GasLab® makes it easy to export data into a .CSV file that can be imported into any industry-standard software or spreadsheet. GasLab® runs on Windows XP or higher, and is free to use with our products.
Tube cap adapters easily convert 20mm standard gas sensors from diffusion to sampling sensors and add the ability to measure barometric pressure, temperature and % relative humidity from the gas sample. Molded polymer. Tube cap adapters are not pre-installed. For accurate results you must mount the tube cap permanently.
Micro-Pump Kit includes all the tools you need to utilize the tube-cap adapters as part of a sampling sensor system.
Nafion Tubing is a highly selective, semi-permeable membrane to water vapor. If gases inside Nafion tubing are wetter than gases surrounding the tubing, drying will occur. If the surrounding gases are wetter, humidification will occur.
Micro Gas Sampling Pumps provide a constant flow of air across the sensor with a tube cap - perfect for bench-top testing of sensors for closed-loop sampling applications.
Probe Enclosure for Development Kits gives a strong and secure container to mount the sensor. Hydrophobic filters available for enclosure for outdoor use.
ExplorIR®-M 20% CO2 Sensor
I bought a CO2 sensor (and O2 sensor) for research work monitoring animals and as a cheap alternative to very expensive systems. Yet to use properly but it seems to be very stable and responsive and I'll likely buy more. Also very impressed with the O2 sensor.
