Hello all, We are developing a sensor using the BME280. We are on the second prototype, to try to get the correct temperature and humidity without any success. In this last prototype, we've etched the board around the sensor and removed most of the cooper connections, but still, we are measuring around 3ºC more than we should and 10% lower humidity. We've assembled two prototypes, one using the hotgun to solder the BME, heating the board, not the sensor, and a second one using a reflow oven with the proper profile, both are presenting the same deviations. When we plug the PCB, the first values are quite correct, but then the temperature starts to rise and the humidity falls to the deviations I explained. Are these deviations linear? Can we compensate for the ~3ºC and ~10% just by adding it or subtracting it from the final values? Is there anything more we can do on the PCB design to solve this? Thanks in advance, Wishes for a great weekend, Regards,
