DHT22 sensor unstable reading value

Hello everyone,

I am new to Arduino and today i've purchased and noticed that the DHT22 sensor is unstable, it keeps increasing and decreasing by 0.1°C at the same time in a very short amount of time.

20:41:03.319 -> Temperature = 17.70 *C     Humidity = 99.90 % 
20:41:04.349 -> Temperature = 17.70 *C     Humidity = 99.90 % 
20:41:05.367 -> Temperature = 17.60 *C     Humidity = 99.90 % 
20:41:06.350 -> Temperature = 17.70 *C     Humidity = 99.90 % 
20:41:07.349 -> Temperature = 17.60 *C     Humidity = 99.90 % 
20:41:08.381 -> Temperature = 17.60 *C     Humidity = 99.90 % 
20:41:09.367 -> Temperature = 17.70 *C     Humidity = 99.90 % 
20:41:10.380 -> Temperature = 17.60 *C     Humidity = 99.90 % 
20:41:11.380 -> Temperature = 17.70 *C     Humidity = 99.90 % 
20:41:12.382 -> Temperature = 17.70 *C     Humidity = 99.90 % 
20:41:13.395 -> Temperature = 17.60 *C     Humidity = 99.90 % 
20:41:14.427 -> Temperature = 17.60 *C     Humidity = 99.90 % 
20:41:15.426 -> Temperature = 17.60 *C     Humidity = 99.90 %

Is there any solution to get a stable temperature?

looks to me you have more problems. 99.90% humidity ? what sketch do you use ? how did you connect the DHT22?

Why are you complaining about a variation of 0.1°C on a sensor that has a resolution of 0.1°C? You're probably simply in between those values. It's not significant anyway as it's accurate to no better than +/- 0.5°C.

The humidity number is nice and stable. Probably simply stuck at that value, as happens all the time with those sensors.
