How to send sensor data (like temperature data from DHT11 sensor) to Google Cloud IoT Core and store it

Question

I am working on connecting a Raspberry Pi (3B+) to Google Cloud and send sensor's data to Google IoT Core. But I couldn't find any content in this matter. I will be so thankful, if anyone would help me, in dealing with the same.

PS: I have already followed the interactive tutorial from Google Cloud itself and connected a simulated virtual device to Cloud and sent data. I am really looking for a tutorial, that helps me in connecting physical Raspberry Pi.

Thank you

You may want to try following along with this community article covering pretty much exactly what you're asking.

The article covers the following steps:

• Creating a registry for your gateway device (the Raspberry Pi)
• Adding a temperature / humidity sensor
• Adding a light
• Connecting the devices to Cloud IoT Core
• Sending the data from the sensors to Google Cloud
• Pulling the data back using PubSub
