Unstable reading from DHT11

Hi!

I am wondering why ma readings from DHT11 aren't stable. Temperature is 28 and every few seconds jumps to 14. The same thing is with humidity. I am using Arduino mega and DHT.h library. Does anybody know what the problem is?

No, no idea, sorry.

Does anybody know what the problem is?

It's either your code, your hardware, or your environment. Look back through your post, and see just how much we know about any of them.

I used it few months ago and it worked just fine.

That's nice. Or a shame.
