DHT22 with wemos D1

#1 Post by remko2000 » 06 Oct 2019, 19:58

I use a wemos D1 with a loose DHT22 to measure humidity. I connect the dht22 with a 10K resistance. Pin 3 (NC) is not connected. I use GPIO 14 for data. I also have tried different esp megabuilds. I also tried to power the dht22 with 5V and 3,3V. I nothing change to the part 'hardware' in esp. Everything I try results in the same problem: within a couple of hours I get 'nan' as value. I googled on this problem but I don't see a clear solution. I am about to give up but maybe someone here have a solution?

You can revert to an older build of about a month ago, to see if the current issue is caused by one of the more recent changes.
If not, then it is not yet fixed.
I know Uzi18 was working on it, but I have no idea what the current status is.
