'''
This decoder handles the proprietary single wire communication protocol used
by the Aosong AM230x/DHTxx series of digital humidity and temperature sensors.

Sample rate:
A sample rate of at least 200kHz is recommended to properly detect all the
elements of the protocol.

Options:
The DHT11 digital humidity and temperature sensor uses the same single wire
protocol with a different encoding of the measured values. Therefore the option
'dht11' must be used to properly decode the communication of a DHT11 device.
