Prototyping IoT with InfluxDB Cloud

InfluxDB Cloud 2.0 is now ready for production use, offering a free tier suitable for prototyping IoT projects. The author of this tutorial created a monitoring system using sensors and Arduino, streaming data to InfluxDB Cloud 2.0 via USB from an Arduino microcontroller. The Python code structures the sensor data into a line protocol format compatible with InfluxDB. A Raspberry Pi is used as an edge gateway to send the data to InfluxDB using its REST API. With minimal effort, the author visualized their sensor data in Data Explorer and set up Slack alerts for critical moisture levels below 100. The tutorial barely scratches the surface of InfluxDB 2.0's capabilities, mentioning potential tools like Telegraf, tags, and Flux but not exploring them in detail.
