All you need to build your own little fine dust sensor & outdoor weather station:
- ESP32 micro controller
- SDS011 laser scattering particle sensor
- BME280 temp/humidity sensor
- Jumper wires
- PVC flexible tube
- PVC pipe for protection
You can get all those parts for ~$30.
A map of particle sensors:
"I am the one who alone exists,
and I have no one who will judge me.
For many are the pleasant forms which exist in numerous sins,
and disgraceful passions,
and fleeting pleasures,
which (men) embrace until they become sober and go up to their resting place.
And they will find me there,
and they will live,
and they will not die again."
