Mobile Sensor for particle matter and NOx/CO Gas is meant as an open project for everyone
Hardware:
- Nova Fitness SDS011 Particle Matter Sensor PM2.5,PM10;
- Temperature, Humidity, AirPressure BME280 °C,%,hPA;
- GPS Sensor NEO-6M GPS;
- NOx CO Breakout-Board CJMCU-4541 [Sensor MiCS-4541 NOx, CO];
- Display SSD1306 OLED
- USB Power Bank
Arduino IDE
Idea based on Airrohr Feinstaubsensor from
- https://luftdaten.info/
- https://github.com/opendata-stuttgart/sensors-software/tree/master/airrohr-firmware
SDS011 Library [sds011_vers] with reading in Query Reporting Mode [Factory Default is active reporting mode]
NOx/CO Sensor Interpreting the values from the MiCS-4514 on the CJMCU-4541 Breakout Board is inspired and based on work from

- Roland Ortner http://myscope.net/auswertung-der-airpi-gas-sensoren/
- OpenairCologne https://github.com/OpenAirCgn/
- own Data Collections for calibration
points of development
- lorawan module
- SD-Card
- save and send data to (https://luftdaten.info, https://opensensemap.org, https://aqicn.org/, http://www.hackair.eu/, ...)
still in working progress
