ESP8266 sensor box with OLED display and fine dust sensor

thingiverse

First version of my sensor box. It contains various sensors for Air Quality / Temperature / Humidity / Fine dust aquisiton. I've never finished the software. The air quality and alcohol sensor need 5V so you have to use a signal converter. In adition the NodeMCU has just one input so a ADC is neccessarily! In the back it has an LED strip which is fixtured without screews.
