Grafana Visualization

info

This tutorial is made for the Air Quality Monitor connected to the Raspberry Pi with the Hub installed on it.

You can use our Pre-Installed Image or your own Raspberry where you will install the Hub

Grafana is an open platform for beautiful analytics and monitoring. It allows you to create nice-looking dashboards that will give you quick insights into your sensor data.

Install Grafana

Linux

info

First, you will need to install InfluxDB.

Start by installing all the needed packages

sudo apt install apt-transport-https curl -y

Add the repository key

curl -sL https://repos.influxdata.com/influxdb.key | sudo apt-key add -

Add repository to the source list

Debian

echo "deb https://repos.influxdata.com/debian stretch stable" | sudo tee /etc/apt/sources.list.d/influxdb.list

Ubuntu

echo "deb https://repos.influxdata.com/ubuntu/ xenial stable" | sudo tee /etc/apt/sources.list.d/influxdb.list

Install the InfluxDB Package

sudo apt update && sudo apt install influxdb

Start the InfluxDB Service to test it

sudo systemctl start influxdb

info

After you tested the InfluxDB, you can move to Grafana.

Install Grafana Dependencies

sudo apt install adduser libfontconfig -y

Install InfluxDB and Enable It

brew install influxdb
brew services start influxdb

info

After you installed InfluxDB, you can move to Grafana.

Install InfluxDB and Enable It

brew install grafana
brew services start grafana

Configure Grafana

To configure Grafana, you will first have to open it and log in:

• http://localhost:3000/ - Grafana is running on your local machine
• http://hub.local:3000/ - Grafana is running on your Raspberry Pi with our Hub installed
• http://"IP address":3000/ - Grafana is installed on your device, you should know the IP address of that device

info

Default User is admin. Default Password is admin.

danger

To make this part work without any additional configuration you need to follow the tutorial for MQTT Strorage (mqtt2influxdb)
