    faulty BME680?

    faulty BME680?

    Hello,

    I have four BME680 and one of them is measuring quite low gas resistances from others. I'm wondering if am facing faulty sensor or it's just normal and it will fix-self after some time?

    I'm using own bsec implementation, three sensors are variing from 120k to 170k ish gas resistance while this one is only around 25k - 37k ish.

    All other data like temperature, humidity, pressure is measured exactly same as others, so only gas resistance is extremely low

    It's not big deal, I can replace this one, but just wanted to know if gas resistance membrane can somehow be broken or it's just coincidence?

     

    Thanks

    Hello,

    Sorry to revive this old thread but I am also having troubles with my sensors. I have 4 BME680, I mounted two of them myself and the others are EVKs from pimoroni and microE. I have tested all the sensors together on the same breadboard and the result I get have a serious offset and difference in sensibility between sensors. I used the oversampling X16 for the temperature, humidity and pressure, set the IIR filter to IIR4 and set the heater at 320 for 150 ms.

    Is this kind of result to be expected ?
