In this tutorial, we will implement a simple temperature logger on the Raspberry Pi 3 and connect four DS18B20 temperature sensors to it. The temperature measurements will be stored in a database along with a time stamp. We have selected InfluxDB as the database engine as this is a time-series database and integrates very easy to Grafana. Grafana will retrieve …
