Show HN: Live Air Quality Monitor

11 benbojangles 2 5/3/2025, 6:51:24 PM github.com ↗

A comprehensive indoor air quality monitoring system built with ESP32-C3 Super Mini and multiple environmental sensors. This project helps you monitor CO2, temperature, humidity, volatile organic compounds (VOCs), nitrogen oxides (NOx), and particulate matter (PM1.0, PM2.5, PM10) to maintain healthy air quality in your home or office.

Cool project, but I’m curious how this is different from other open source air quality monitoring projects like AirGradient?

How does this compare to ESPHome? I understand it can do this job relatively straightforwardly and can pipe the data into either Home Assistant or Prometheus, so as to not reinvent the web interface wheel.
