Are both of your DHT11 and DHT22 placed at the same location?

Regarding the value, 99% could be possible, since the temperate is also dropping, so water saturation rises.

However, those DHT sensors are neither very reliable, nor accurate. There are better alternatives, like the Bosch BME280 or similar.

not. IN is inside and OUT is outside (approx. 0.5-1m). I tried them side by side. after a few hours the same thing happened - humidity 99.9%.

I'll try the sensor you're describing to me

well thank you
