BME680 InfluxDB and Grafana Setup

This repository contains the code and configuration necessary to set up a system that reads data from a BME680 sensor, stores it in an InfluxDB database, and visualizes it with Grafana. Additionally, it collects system metrics using Telegraf and visualizes them in Grafana (Optional, for RPi temperature monitoring & others). The setup uses Docker Compose to manage the services.

Prerequisites

  • Docker
  • Docker Compose
  • A BME680 sensor
  • A Raspberry Pi/Arduino/ESP8266/ESP32 or any other microcontroller that can read data from the BME680 sensor

Getting Started

1. Clone the repository

git clone https://github.com/yourusername/bme680-influxdb-grafana.git
cd bme680-influxdb-grafana

2. Create a .env file & configure the environment variables

cp docker-compose.env .env

3. Build and run the containers

source .env
docker compose up -d

This will start three services:

  • server: The service that reads data from the BME680 sensor and writes it to InfluxDB.
  • influxdb: The InfluxDB database.
  • grafana: The Grafana service for visualizing the data.
  • telegraf: The Telegraf service for collecting system metrics. Custom exec for rpi temp (Optional)

4. Configure Grafana

Once the containers are running, you can access Grafana at http://localhost:3000. Follow these steps to configure it:

  1. Log in: Default username and password are admin.
  2. Add InfluxDB data source:
    • Navigate to Configuration > Data Sources.
    • Click Add data source and select InfluxDB.
    • Set the URL to http://influxdb:8086.
    • Enter the organization, bucket, and token from your .env file.
    • Save & test the data source.
  3. Create a dashboard:
    • Import json file from the grafana directory.
    • Or create a new dashboard and add panels to visualize the data from the BME680 sensor.

5. Volume Mounts Permissions

If you encounter permission issues with the volume mounts, you can change the permissions of the data directory:

sudo chown -R 472:472 data

# example on my case
cd /var/lib/docker/volumes
sudo chown -R 472:472 bme680-server_grafana-data/
sudo chown -R 472:472 bme680-server_influxdb-data/
Notes:
  • The dashboard for metrics is a modified smaller version of the Telegraf: system dashboard
  • Why use env_file in telegraf? I have no idea why the env vars are not substituted properly when passed in environment: ; for some reason passing in env_file works. Reference
