# Overview

This Raspberry Pi IoT will build an IoT system that monitors sensors using InfluxDB, MQTT, and Grafana. In other words, we will build a dashboard based on Grafana that visualizes the data acquired by sensors.

* **Raspberry Pi** acts as a central server that runs InfluxDB, Mosquitto, and Grafana.
* **InfluxDb** is a time-series database.
* **MQTT** is a network protocol that transports messages between devices for example in this project, sensors, and InfluxDB.
* **Grafana** is an interactive data visualization web application.
