Izinga lokushisa le-I2C elivikelayo elivikela uthuli elingangeni manzi kanye nenzwa yomswakama ohlobene nendawo ebiyelwe ngepulasitiki
HENGKOI-probe yenzwa yokuswakama engangeni manzi ihlinzeka ngezigaba ezi-2 zokungangenisi kwamanzi. I-PCB yangaphakathi inokuvikelwa kokugcotshwa kanye ne-encapsulation futhi indlu ye-humidity probe yenziwe ngezinto ezivimbela amanzi nge-polyethylene. Kuyindlela ekhethekile yezinto eziphefumulayo ezingangeni manzi evumela ama-molecule omoya ukuthi angene ngokuvimbela la maconsi amanzi ukuthi angavuzi kule ndawo. Inzwa ayilimele ngemva kokucwilisa amanzi isikhathi eside. Kufaka phakathi i-10k pull-up resistor kanye ne-0.1uf filter capacitor. Ivumela inzwa ukuthi isetshenziswe ngokuqondile ne-microcontroller efana ne-Arduino.
Isici:
Ukuthembeka okuphezulu nokuzinza kwesikhathi eside
Ukuzilinganisa kwangaphakathi
Ngokwedijithali, ukulungiswa kufika ku-14bit
Isakhiwo somkhiqizo sihle, silungele ukusetshenziswa kwensimu kanye nokuhlanganiswa komkhiqizo
