# 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. ![](/files/-MDQP-N58wP_I-dK1OLL) * **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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
