● Aʻo Huahana
Hoʻohana ʻo LF-0020 water temperature sensor (transmitter) i ka thermistor kiʻekiʻe e like me ka ʻāpana ʻike, nona nā hiʻohiʻona o ke ana kiʻekiʻe a me ke kūpaʻa maikaʻi.Hoʻohana ka mea hoʻouna hōʻailona i ka module advanced circuit integrated module, hiki ke hoʻololi i ka mahana i ka volta pili a i ʻole ka hōʻailona o kēia manawa e like me nā pono like ʻole o nā mea hoʻohana.He liʻiliʻi ka mea kani i ka nui, maʻalahi e hoʻouka a lawe ʻia, a he hana hilinaʻi;Hoʻohana ia i nā laina ponoʻī, linearity maikaʻi, ka mana hoʻouka ikaika, ka lōʻihi o ka hoʻouna ʻana, a me ka ikaika anti-interference.Hiki ke hoʻohana nui ʻia no ke ana ʻana o ka mahana ma nā kahua o ka meteorology, kaiapuni, keʻena hana, ʻoihana a me ka mahiʻai.
