DHT22 giving too high humidity value

Other Hardware Sensors
1

I am getting too high humidity values from DHT22 sensor. My system consists of multiple DHT22 connected to an Arduino Uno Wifi, using the DHT library. For reference I use two "Xiaomi Bluetooth-compatible Temperature Humidity Sensor". DHT22 gives values that are typically 5%RH higher, and sometimes up to 15%RH higher. E.g. the Xiaomi sensor would show 61%RH, and my DHT22's would report 67%RH and sometimes 72%RH. The DHT22 values typically match each other. My Xiaomi reference sensor track each other, and never show crazy excursions. My DHT22 are powered down between reads, and read 10-60 seconds after being powered up.

Anybody with similar experience ?

No, my experience with the DHT22 are not that good, they are worse :dizzy_face:
There are better humidity sensors, such as the HTU31, HTU21D-F, BME688. You find the at Adafruit.
