In this section, we are going to build a sample application using the Google Cloud IoT Core.
Designing a sample application
Solution
The solution we are going to build is going to be similar to the one from Chapter 4, AWS IoT. We are going to connect a DHT11 sensor to Raspberry Pi 3 and then transmit the data over GCIC using MQTTS. Once the data reaches the Pub/Sub topic, we will pass this data to a Google Cloud Function. The Google Cloud Function will then take this data and insert it into Google BigQuery. Finally, using a Google Data Studio BigQuery connector, we will connect the two services and build our visualizations and reports.
In the next section, we are going to look at the overall architecture of the solution.
