    BME680/688 in hydrogen environment

    BME680/688 in hydrogen environment

    Hello,

    can the BME680 or BME688 sensors be used to measure temperature, pressure and humidty in a (otherwise) pure hydrogen environment?

    Main usecase is to determine pressue and temperture at the inlet of a PEM fuel cell stack used in a supermileage prototype vehilce built by a student team.

    We already use those sensors in our vehilce for fuel cell outlet air temperature and humidity. The hydrogen data is needed to regulate our custom hydrogen humidifier used to achive better efficency in our application.

    Best,

    Woody

    Hi Woody_H2M,

    Yes, as long as the measurement values of temperature, pressure, and humidity are within the spec in the data sheet.

    Hello BSTRobin,

    great, thanks!

    Would an hydrogen environment have negative influence on the sensors lifetime/durability?

    Also, does the sensor need specific calibration for humidity readings in this case?

    Best,

    Woody
