I have a DHT11 to measure the moisture in a room. I've noticed that what previously registered as above 90 now is read as around 10! The value still increases if it gets more humid, but obviously what values I used to define when it is humid and not are no longer valid.
What causes it to degrade like this? Is it simply not a quality product meat for use over time? This has only been in use for a month. But I noticed this was a gradual deterioration.
What should I get instead? I need a reliable sensor.
