The DHT11 temperature and humidity sensor

The DHT11 is a temperature and humidity sensor using its own private protocol. Fortunately a driver is again available in the micro Python library implementing this protocol and making the use of the module very simple.

As before I wrote a small hardware test program verifying that I can correctly read temperature and humidity values before integrating the sensor into our Cayenne IoT network.

Here is the hardware test code:

and here the Cayenne version publishing the temperature and humidity readouts.
