Hi, are there recommendation how to protect BME280's electrical connections from enviromental?
Our company uses BME280 as Temperature/Pressure/Relative Humidity sensor in outdoor ecology hardware. So the sensor PCB is working in conditions RH up to 100%, T=-40...+40, it is caused electrical connections problem (tracks/contact pad/etc not protected from the environment).
We want to protect electrical connections from the environment, without breaking "Handling, soldering & mounting instructions" (https://www.bosch-sensortec.com/media/boschsensortec/downloads/handling_soldering_mounting_instructi...
Do you have any recommendation what we can use as insulator?
Now we are using CRC Urethan 71 vernis isolant, but not sure it is good.
Thanks

Hi Eugene1215,
Please see below comment for reference,
1, As the description from BME280 HSMI document, we don't recommend total and partial covering the sensor.
2, Based on the HSMI chapter5.1
