Use a computer to emulate devices of temperature connecting to AWS IoT

I modified the sample basicPubSub of the project aws-iot-device-sdk-python to develop the Python tool AwsIotPythonTest.py to test AWS IoT service.

My project is AwsIotPythonTest.

We can use the tool to emulate 3 connected devices, two sensors of temperature and one monitor. They are run in PC environment by opening 3 consoles. When running, they connect to AWS IoT service and exchange temperature information via MQTT as below picture.

The Sensor 1 and Sensor 2 devices connect to AWS IoT Service and publish temperature information to the service. The Monitor device connects to the service and subscribe it to receive temperature information coming from sensor devices. The publish/subscribe model follows MQTT. I described the idea of emulator in the project AwsIotPythonTest in details.
