In the previous section, we have seen the use case of uploading temperature data only. Now, with mini weather station, we are going to deal with three parameters:

• Temperature
• Pollution level
• Sound level

All three parameters will be uploaded to the cloud and displayed live on the dashboard. The project will be divided into parts, which will make it easier to understand, and we will also tackle other complex projects:

• Architecture of the system
• Sensor and hardware components and detailed circuit diagram
• Locally acquiring data and displaying it on the console
• Uploading the data to the cloud
• Visualizing the data

Most details were shown previously using a temperature sensor, so we won't go into much depth, but we will cover all aspects.
