Iot Core | Google Iot | Googlecloud Tutorial

Introduction

Google Cloud IoT Core is a fully managed service that allows you to easily and securely connect, manage, and ingest data from globally dispersed devices. It enables you to leverage Google Cloud's data analytics services to gain insights from your IoT data. This tutorial will guide you through the steps to set up and use IoT Core from start to finish.

Setting up Google Cloud IoT Core

Before you can use IoT Core, you need to set up a Google Cloud project and enable the necessary APIs.

1. Go to the Google Cloud Console and create a new project.

2. Enable the IoT Core API for your project.

3. Install the Google Cloud SDK, if you haven't already. You can download it from here.

Creating a Device Registry

A device registry is a container for devices. It holds a collection of devices that share the same configuration and authentication details.

Create a device registry using the following command:

gcloud iot registries create --project= --region= --event-notification-config=topic=

Adding Devices to the Registry

Next, you need to add devices to your registry. Each device must have a unique ID and authentication keys.

Add a device to the registry using the following command:

gcloud iot devices create --project= --region= --registry= --public-key path=,type=rsa-x509-pem

Publishing Telemetry Data

Devices can publish telemetry data to the cloud, which can then be processed and analyzed using Google Cloud services.

Publish telemetry data using the MQTT protocol:

mosquitto_pub -d -q 1 -h -p 8883 -i "" -u 'unused' -P '' -t '/devices//events' -m '' --cafile --cert --key

Subscribing to Configuration Updates

Devices can also subscribe to configuration updates from the cloud. This allows you to manage and control devices remotely.

Subscribe to configuration updates using the MQTT protocol:

mosquitto_sub -d -q 1 -h -p 8883 -i "" -u 'unused' -P '' -t '/devices//config' --cafile --cert --key

Monitoring and Logging

Google Cloud provides tools to monitor and log activity within your IoT Core infrastructure.

You can use Stackdriver Logging to view logs and Stackdriver Monitoring to set up alerts and dashboards.

Conclusion

This tutorial has provided an overview of how to set up and use Google Cloud IoT Core. By following these steps, you can connect, manage, and ingest data from your IoT devices, leveraging Google Cloud's powerful analytics tools to gain valuable insights.
