BUG DESCRIPTION
Hello *. I have a problem with my DHT22. After some time (hours, days) I get null values from sensor (sometimes both). So I attached 2 sensors to my raspberry pi via GPIO2, 27.
The results are confusing:
If one sensors show null, one other may keep reporting good values!
Reboot of rpi does not help at all.
Hard reset (Power off / on) of rpi always works.
Power reset (3.3-5V off / on) of a sensor only SOMETIMES works.
Data reset (pull cable and replug) of sensor works almost always.
If data reset (on ONE sensor) works, other null sensor will start reporting good values as well!
TO REPRODUCE
Nothing it happens all time, works after reboot for a minute then it starts to get null more and more null. After some hours or so only null values.
