The developer has to develop electronics, PCB, all necessary software, gadget GUI, web scripts, Android and IOS app and enclosure. The Key sensors are for CO2 measurements, Particulate Matter measurements, VOC, Humidity and Temperature measurement, Baromatric measurement, proximity sensors.
Device GUI should be customizable so we can change languages and graphics periodically. These will be kept in different files on the SD card and can be selected/uploaded through app.
