Processing (IoT sensor) data with InfluxDB

Friday, September 27 – Day 2 - 16:45 - Room 3

Sensors give us a wealth of information. But how do we store the information and how do we make it available in a readable way? In this session, I will show you how you can send the sensor data to an InfluxDB data storage with a Spring Boot application. InfluxDB is a time series database which is a perfect fit to store sensor data. It’s possible to send the data by making a REST call to InfluxDB or by using the Java InfluxDB client.

The example (including a live demo) is based on a Raspberry Pi with the following sensors: -BME280 sensor connected to the GPIO ports of a Raspberry Pi – Xiaomi Mijia temperature and humidity sensor connected via Bluetooth to the Raspberry Pi.
After the sensor data is stored, we want to make it available in a nice graphical way. Therefore, we use the Grafana and Chronograf dashboards.
