Show HN: Live Air Quality Monitor

https://github.com/benb0jangles/Air_Quality_monitor
19•benbojangles•9mo ago
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.

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.
benbojangles•9mo ago
I guess this board setup has more freedom over sensor code control and adjustment, is not limited to local network it can be monitored anywhere. The user could easily setup the board to use esphome too
ssuds•9mo ago
Cool project, but I’m curious how this is different from other open source air quality monitoring projects like AirGradient?
benbojangles•9mo ago
This is a DIY board and roughly 150 cheaper than airgradient
wkat4242•9mo ago
It probably doesn't even need a board, you can just wire all the sensors in a box and solder the cables. Each sensor only has 3 or 4 and so does the display.

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.

benbojangles•9mo ago
Wires are chaotic and a point of failure
wkat4242•9mo ago
True but they do facilitate more flexible placement. I use them a lot for one off projects.
benbojangles•9mo ago
Have you tried kicad
wkat4242•9mo ago
No I usually use CircuitMaker. I like their big footprint database.
ssuds•9mo ago
For sure. Was just curious as they started out with a super basic DIY setup https://www.airgradient.com/documentation/diy/ (which can be implemented without the PCB even, as another commenter in this thread suggested) so I was wondering if there was a functionality you found was missing that sparked you to create this project!
benbojangles•9mo ago
From reading their specs, my pcb uses higher spec components (esp32, scd41, sgp41), newer technology, better accuracy, more sensing capability (VOC, & N0x)
Emmarof•9mo ago
Where did you buy your components from?
benbojangles•9mo ago
Where did I buy my components? Or where can people buy their own components? YMMV.
