BME280 giving weird humidity measurements

[moiz_elec]

Hello,

We are currently in Beta test with one of our customers before deployment.

We encounter noise spikes around 60% in the humidity data only when the electronics is outdoor. The main electronics is resined and IP and the BME280 is in a PTFE filter.

I am sending 2 screenshots:

• First one is for a module that has been sitting outside for 1 month. Temperature and pressure are OK. You can see random spikes in the humidity data.
• Second slide is for another module, identical to the previous one. It has been indoor for around 2 weeks with clean humidity data and as soon as it went outside some noise spikes in the humidity appeared.

I can also add that when the first module was sitting indoor, it had no errors in humidity data.

In conclusion noise spikes are only present outdoors.

Is that a known issue ?

Do you recommend any action ?

Thanks
