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.
But a board is cleaner and they're super cheap to get made in China unless you're shipping to the US I guess lol.
I've built sensor boards like these too. But more with Dallas one wire sensors to measure temperature in different locations of central heating systems.
