NOTE:
1. The TH01 App temperature under 0℃,the humidity data will keep the last temperature >0℃ data,
The humidity sensor will stop work.
2. The TH01 App temperature less than -20℃, The temperature sensor need change to the out
induce, The humidity function will cancel, Because the TH01 32.768khz only working >-20 ℃ .Working
<-20 the error will too large.
