The LuminOX LOX-02 Oxygen sensor measures ambient oxygen levels using the principle of florescence quenching by oxygen. This provides the benefits of lower power requirements and a longer lifespan than typical oxygen sensors.

The Development Kit combines the LOX-02 sensor with barometric pressure, temperature and % relative humidity sensors on board with built-in data logging. Measurements can be taken of all sensors using our free Gaslab software.

Combined with MX board the LOX-02 provides accurate oxygen measurement over a wide environmental range without the need for additional system components.


  • LuminOX sensor provides low drift, low cross-sensitivity
  • MX Board includes barometric pressure, temperature and % relative humidity sensors
  • MX Board allows for easy sensor calibration
  • MX Board adds RS485 Industry-standard Interface
  • Easy integration; compact & low power


OX-0052 Sensor for integration into high-volume OEM products.

CM-42951 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-42950 MX Board Same functionality as the development kit without USB cable or software.
