Description
Hi there,
I'm using Arduino UNO and the new variant of the Asair DHT11 (not the Aosong) sensor over 3.3v.

Everything is working just fine until the sensor reading get to 0 degree celsius and it just wont go below.
Outside right now is -3c
btw. I'm using library version 1.3.0
Thank you for your support!

Research direction
No source file or test is named in the report. Start by reproducing the reading with an Arduino UNO, the Asair DHT11 variant at 3.3V, and library version 1.3.0, then trace the temperature-reading path. Done means the library correctly reports temperatures below 0°C for the reported sensor setup.
