Nā hiʻohiʻona huahana
● Hoʻohana ʻia ka mīkini calibration maʻalahi e calibrate i ka sensor i kēlā me kēia, a ua hoʻomaikaʻi nui ʻia ka pololei.
● ʻAʻohe heʻe ma muli o ka hoʻohaʻahaʻa ʻana o nā mea seramika.
● E kanu wale i ka mea ʻike, hoʻonohonoho i ka uaki a me ke ana ʻana, hiki iā ʻoe ke hoʻomaka e hōʻiliʻili i ka ʻikepili me ka ʻole o ka hoʻonohonoho ʻana.
● Epoxy resin overlapping injection molding kaʻina e hōʻoia i ka mea kūpono no ka lōʻihi-makahiki kahua noiʻi.
● Hiki ke hāʻawi i nā kikowaena a me nā polokalamu, hiki ke hoʻohui i ka LORA LORAWAN WIFI 4G GPRS, hiki ke nānā i nāʻikepili ma nā kelepona a me nā PCS.
Hoʻohana huahana
● E hoʻoholo mua i ka hohonu o ka hoʻokomo ʻana a me ke kūlana o ka wai wai lepo;
● E lawe i kahi laʻana lepo ma kahi e hoʻokomo ai, e hoʻohui i ka wai a me ka lepo i ka laʻana o ka lepo, a hoʻopiha i ka ʻike wai wai lepo me ka lepo;
● Hoʻokomo ʻia ka mea ʻike i uhi ʻia me ka lepo i kahi hoʻonohonoho, a hiki ke hoʻihoʻi ʻia ka lepo.
Nā noi huahana
Hiki ke hoʻohana nui ʻia kēia huahana i ka irrigation, drainage, e hāʻawi i ke kumu ʻepekema no ka ulu ʻana o nā mea kanu a me nā wahi maloʻo, ka lepo maloʻo, alanui alanui a me nā ʻano ʻē aʻe o ka noiʻi wai lepo.

FAQ
Nīnau: He aha nā hiʻohiʻona nui o kēia mea ʻike wai lepo?
A: He mea waiwai ia a me ke ana ʻana i ka nui o ka wai lepo me ka ʻole o ka mālama ʻana a me ka calibration, hoʻopaʻa maikaʻi ʻia me ka wai wai IP68, hiki ke kanu ʻia i ka lepo no ka nānā mau ʻana o 7/24.
Q: Hiki iaʻu ke loaʻa nā laʻana?
A: ʻAe, loaʻa iā mākou nā mea waiwai e kōkua iā ʻoe e kiʻi i nā laʻana i ka wā hiki iā mākou.
Q: He aha ka mana maʻamau a me ka hoʻopuka hōʻailona?
A: 5 ~ 24V DC (inā he RS485 ka hōʻailona puka)
12 ~ 24VDC (inā ʻo ka hōʻailona hoʻopuka he 4 ~ 20mA)
Nīnau: Pehea e hiki ai iaʻu ke hōʻiliʻili i ka ʻikepili?
A: Hiki iā ʻoe ke hoʻohana i kāu logger data ponoʻī a i ʻole module hoʻoili uila inā loaʻa iā ʻoe, hāʻawi mākou i ka protocol communication RS485-Mudbus. Hiki iā mākou ke hāʻawi pū i ka LORA / LORANWAN / GPRS / 4G i hoʻohālikelike ʻia i ka module uila uila inā pono ʻoe.
Q: He aha ka lōʻihi o ke kaula maʻamau?
A: ʻO 2m kona lōʻihi maʻamau.Akā hiki ke hoʻopilikino ʻia, hiki i ka MAX ke 1200 mika.
Nīnau: He aha ke ola o kēia Sensor?
A: Ma kahi o 3 makahiki a ʻoi aku paha.
Q: Hiki iaʻu ke ʻike i kāu palapala hoʻokō?
A: ʻAe, maʻamau he 1 makahiki.
Q: He aha ka manawa hoʻouna?
A: ʻO ka maʻamau, e hāʻawi ʻia nā waiwai ma 1-3 mau lā hana ma hope o ka loaʻa ʻana o kāu uku.Akā, pili ia i kāu nui.
