Grafana (https://github.com/grafana/grafana) on the screenshot above, can be viewed live on https://olegy.kz/

Raspberry-PI-based solution to analyze the air quality (CO2, temperature, humidity, pressure)

How it works ⚙️

• For humidity, temperature and pressure data I'm using BME280 sensor;
• CO2 ☣️ concentration data is provided by MH-Z19B sensor;
• sniff.rb script execution sends single measurement to local Telegraf instance;
• For continuos monitoring sniff.rb execution should be executed by external scheduling system (CRON, for instance)

Structure

Data utilization 📊

Obtained values are reported to the local Telegraf instance - then they could be utilized in according to Telegraf configuration file. In my case, I'm using InfluxDB as telegraf output and Grafana as UI for InfluxDB
