I was reading the lines in SimpleDHT.h and its states:

// For DHT11, in H, such as 35H. // For DHT22, in RH%, such as 53%RH. 

However, the DHT11 data sheet states it returns Relative Humidity.
See https://www.electronicoscaldas.com/datasheet/DHT11_Aosong.pdf

I get a value of 35 right now at 23°C - and if that was absolute humidity the RH% would be well over 100%

I want to suggest that the .h file gets updated as a simple documentation issue.
