#39: DIY air quality sensor, part 2 – “Display” version ...

· It’s surprisingly easy to make your own simple air quality sensor. All you need is a cheap laser-scattering particulate matter sensor, a Wemos D1 Mini, a soldering iron, and Tasmota. Part 1 showed how to make the simplest possible air quality sensor. Make sure you’ve seen that first, because Part 2 continues from Part 1 to add a 128×32 pixel OLED display and a mode button. We’re also ...
