I have a high failure rate of BMP384 pressure sensors. Greater then 50%. The units that work seem to work fine, the ones that fail will read 10 to 50 kPa below ambient atmospheric pressure.
Reading forums it appears that these are sensitive to washing and chemicals. I cleaned one board with IPA and an acid brush and the sensor started to read 42kPa atmospheric pressure. Nominal in my area is about 89kPa. Is this an expected result of cleaning? Did I damage the gel?
Assuming the software is correct because we have units that work fine, are these devices this sensitive to chemicals and dust? Is there a better option? Should I be considering the BMP390?
Thanks
