BME280 How to use it outdoors
-
So, this story also continues. After having these problems, I brought the sensor into the house and left it running for the past several weeks in the living room. Actually it is working fine. No more problems.
Now, for Christmas, I have brought it back outside to the birdhouse. And it is still working fine, even at -10 °C. Let's see how long it will last this time.
What I also noticed is that now I have a second of these in the greenhouse where the humidity is definitely from time to time 100%. At 4°C. But both outdoor sensors somehow never reach 100%, but stop somewhere between 85-90%. It seems they are not made to detect 100% humidity.
-
Now after 2-3 month more outside the sensor seems to be finally dead. No reaction anymore. Also the 2nd one in the greenhouse does not reply anymore. I'll have to check. The one in the living room is fine.
It seems that at least the ones I bought are not really lasting long outdoors.

Interesting idea, the ptfe tape. I will try it with the next sensor!
So, only the outdoor sensors fail. It is now more than one that failed.
I have one in the living room -- perfect.
And, very strange: I have one in the green house. Huge T differences, sometimes very hot, and often 100% humidity. Actually conditions should be worse for this sensor compared to the outdoor sensor. But: it is just fine.
Weird.

@karl261 Do you happen to live near te sea? Because salty air wreaks havoc on anything sooner or later. Tiny electronics rather sooner...
I have a BME280 outside and that's been running for over a year now. It's pretty well protected though, but it catches a few hours of direct sunlight per day.

Hi, no, I live rather far from the sea. I don't know what is killing the outdoor sensor. The same in the greenhouse survives much weirder temperatures and humidities.

@karl261 Any update on this topic?
Are you still struggling with that your BME280s don't seem to last long time outdoors?
Anyway. My crappy BME280 clone that I bought on ebay for $8.98 (in December 2016) lasted only for 4 days.
Now I will have to take down my weather station and repair it.
I will now buy an original Adafruit BME280 for 289 SEK (32$) + postage. I hope that one will last.

Now after 2-3 month more outside the sensor seems to be finally dead. No reaction anymore. Also the 2nd one in the greenhouse does not reply anymore. I'll have to check. The one in the living room is fine.

Quite old thread, but wanted to provide an update:
I have a BME280 up and running since about 1 year now. It is in the weather station outside on the roof. It is vented very well but protected from direct exposure to sun, wind and rain. Readings are reliable. What I did is treating the whole board except the sensor chip with this:
