Intro
I needed a PM2.5/PM10 sensor during this winter season. I wanted to monitor more than one room and did not want to buy multiple expensive devices.
This is an eclosure designed to fit 3 devices:
- a PM2.5/PM10 dust sensor
- a Wemos ESP8266-based board with an OLED display
- a digital humidity and temperature sensor
