Arjen knew that an open-source library was available for reading the sports sensors. On that basis, he created an app that sends the data to KPN’s IoT platform: the KPN Things Platform. “Every five seconds, the app sends a message with data such as speed, position, altitude, cadence, and heart rate. Then, I linked the KPN Things Platform to the Azure Event Hub. After processing by Stream Analytics, the data ends up in an SQL database.”
