Zuno DHT Library

An Arduino library for the DHT series of low-cost temperature/humidity sensors. The library can work with any pin For more infomation about pins of Z-Uno here Note that DHT uses shared peripherals: TIMER0 или TIMER1.
The library will try to use TIMER 0, if it is busy then it will try to use TIMER1
Peripherals can be used by only one biocell at a time.
Also, during the polling of the sensor, one DMA channel is used for a short time.
Polling the sensor more than once every 2 seconds is useless.
