This sounds like something is floating or not connected.
You get random readings like this when an input is not connected to anything.

What happens when you connect a pot to those inputs? Can you see the readings follow the pot? If not check your wiring again.

Sorry for late reply.

Problem is solved after cleaning the circuit with acetone.
Probably some dirt were creating problem. I didn't clean properly after soldering.. my fault.
But I am wondering why this affected only temperature sensor...
