	~~The idea is to put up particulate matter sensors up at RevSpace.~~

	~~Stuff to figure out:~~
	* firmware (the easy part)
	* a place to put up the sensor(s), one in each room?
	* how many does revspace need/want?
	* a PCB?
	* a housing for the sensors, could be laser cut or 3d-printed
	* financing:
	** create a cost estimate
	** get financing in advance to avoid spending a lot of personal money on a project that might not complete because of external dependencies

	~~Proposal:~~
	* build a bunch of PM sensors, each containing an ESP8266 + PMS7003 particulate matter sensor + BME280 humidity/temperature sensor
	** PMS7003 is not the "default" luftdaten sensor (SDS011), but it is supported, actually reports a bit more (particle counts, PM1.0)
	** BME280 is used to measure humidity, so we can correct for that. As a side effect, we get (case) temperature and atmospheric pressure.
	* the sensor reports particulate matter concentration over revspace MQTT, at a regular interval
	* preferably make it "Luftdaten compatible" too so it can run the luftdaten firmware (with automatic updates)
	* get extra parts for one more complete module, that will be the development model
	* get extra parts for one more complete module, to participate as a Luftdaten sensor
