WiFi weather station with e-ink screen

Tema ovoga zadataka je bilo osmisliti meteorološku postaju koja kao zaslon ima e-ink (e-paper) zaslon vrlo niske potrošnje na kojem će se prikazivati vremenska prognoza i izmjereni podaci poput temperature zraka, relativne vlaţnosti zraka, tlak zraka i CO2 (eCO2) u zraku. Rad mora trošiti što je manje moguće energije uz pomoć low power reţima rada. Rad mora koristit WiFi mreţu za spajanje na Internet da bi se dohvatila vremenska prognoza. Osim toga, rad mora izmjerene podatke pohranjivati na neku vrstu memorije iz koje kasnije te podatke moţe dohvatiti i prikazati. Poţeljno je da se izmjereni podaci postave na Internet, te da ih se isto moţe po potrebi dohvatiti i prikazati. Dodana je i vanjska jedinica koja mjeri podatke poput temperature zraka, tlaka zraka, relativne vlaţnosti zraka, UV zraĉenje, koliĉinu svjetlosti, koliĉinu sunĉevog zraĉenja, brzinu vjetra i smjer vjetra. Podaci se šalju periodiĉno unutrašnjoj jedinici putem radio veze. Unutrašnja i vanjska jedinica koriste bateriju i solarni panel kao izvor energije.The task of his project was to make a weather station that uses e-ink (e-paper) display that has extremely low power consumption for displaying measured data such as air temperature, relative air humidity, atmospheric pressure and concentration of CO2 (eCO2) in the air. The device needs to use as little energy as possible by using low-power mode. The device also has to use WiFi technology in order to connect to the Internet and get the weather forecast data. Also, the device has to store measured data in some kind of memory device from where data can be fetched and displayed. Preferably, the device can send data to the Internet and also can get the same data if needed. There is also added outdoor unit device that measures data such as temperature, relative air humidity, atmospheric pressure, UV radiation, light intensity, irradiated solar power, wind speed and wind direction. Data is transmitted to the indoor unit by using RF communication. Both indoor and outdoor units are using batteries and solar panels as sources of power
