'''
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 AM230x and DHTxx digital humidity and temperature sensors use the same
single-wire protocol with different encoding of the measured values.
Therefore the option 'device' must be used to properly decode the
communication of the respective sensor.
