Connecting your first device – sensing at the edge

In this section, you will deploy a new component that delivers the first sensing capability of your edge solution. In the context of our HBS appliance monitoring kit and hub device, this first component will represent the sensor of an appliance monitoring kit. The sensor reports to the hub device the measured temperature and humidity of an attached heating, ventilation, and air conditioning (HVAC) appliance. Sensor data will be written to a local topic using the IPC feature of IoT Greengrass. A later section will deploy another component that consumes this sensor data.

If you are using a Raspberry Pi and a Sense HAT for your edge device, the temperature and humidity measurements will be taken from the Sense HAT board. For any other project configurations, you will use a software data producer component to simulate measurements of new data. Component definitions for both paths are available in the GitHub repository, in the...
