Temp / Humid Sensor stuck ?

[Winjas]

Odd question, but im still in the learning and prototyping stage here.

I have three temp/humid sensors made from Pro Minis and DHTT22 sensors running on Mysensors nodes. All three had been running for 2 weeks working very well.

Last 24hrs one of my sensors has been stuck on same temperature and humidity, 26c and 92% and hasn't moved. To check it i placed node next to another node to see if they read the same. No, faulty one still on high stuck figures.

Simple as a dodgy DHT22 sensor or something else i should check ?
