Nā kikoʻī huahana
Nā hiʻohiʻona
●Highly sensitive condenser microphone, kiʻekiʻe precision, ultra stable
● Loaʻa i ka huahana ke kamaʻilio RS485 (MODBUS standard protocol), hiki i ka mamao kamaʻilio kiʻekiʻe ke hiki i 2000 mika
●ʻO ke kino holoʻokoʻa o ka meaʻike i hanaʻia i ka 304 stainless steel, me ka makaʻuʻole i ka makani, ka hau, ka ua a me ka hau, a me ka anti-corrosion.
E hoʻouna i kahi kikowaena kapua a me nā lako polokalamu
Hiki ke hoʻohana i ka LORA / LORAWAN / GPRS / 4G / WIFI hoʻoili ʻikepili uila.
Hiki iā ia ke RS485, 4-20mA, 0-5V, 0-10V puka me ka module uea a me ka server a me ka lako polokalamu e ʻike i ka manawa maoli i ka hopena PC.
Hoʻohana Huahana
Hoʻohana nui ʻia no ka nānā ʻana i ka manawa maoli o nā ʻano leo like ʻole e like me ka walaʻau kaiapuni, ka walaʻau wahi hana, ka walaʻau kaʻa hana, a me nā wahi ākea.

FAQ
Q: He aha ka mea o kēia huahana?
A: Hana ʻia ke kino sensor me 304 stainless steel, hiki ke hoʻohana ʻia no waho a makaʻu ʻole i ka makani a me ka ua.
Q: He aha ka hōʻailona kamaʻilio huahana?
A: Digital RS485 pukana, TTL 5 /12, 4-20mA, 0-5V, 0-10V pukana.
Nīnau: He aha kāna volta hoʻolako?
A: Hiki ke koho i ka mana mana DC o ka huahana no ka TTL i ka mana 5VDC, ʻo ka huahana ʻē aʻe ma waena o 10 ~ 30V DC.
Q: He aha ka mana o ka huahana?
A: ʻO 0.1 W kona mana.
Q: Ma hea e hoʻohana ʻia ai kēia huahana?
A: Hoʻohana nui ʻia kēia huahana ma nā ʻano like ʻole e like me ka home, ke keʻena, ka hale hana, ke ana kaʻa, ke ana ʻoihana a pēlā aku.
Nīnau: Pehea e hōʻiliʻili ai i ka ʻikepili?
A: Hiki iā ʻoe ke hoʻohana i kāu ʻikepili ponoʻī a i ʻole module hoʻoili uila.Inā loaʻa iā ʻoe kekahi, hāʻawi mākou i ka protocol kamaʻilio RS485-Modbus.Hiki iā mākou ke hāʻawi i nā modula hoʻoili uila ʻole LORA/LORANWAN/GPRS/4G.
Nīnau: Loaʻa iā ʻoe nā polokalamu like?
A: ʻAe, hiki iā mākou ke hāʻawi i nā kikowaena pili a me nā polokalamu.Hiki iā ʻoe ke nānā i ka ʻikepili i ka manawa maoli a hoʻoiho i ka ʻikepili mai ka polokalamu, akā pono ʻoe e hoʻohana i kā mākou ʻohi ʻikepili a me ka mea hoʻokipa.
Q: Pehea e hiki ai iaʻu ke loaʻa nā laʻana a i ʻole kahi kauoha?
A: ʻAe, loaʻa iā mākou nā mea waiwai, hiki ke kōkua iā ʻoe e kiʻi i nā laʻana i ka wā hiki.Inā makemake ʻoe e kau i kahi kauoha, e kaomi wale i ka hae ma lalo a hoʻouna mai iā mākou i kahi nīnau.
Q: He aha ka manawa hāʻawi?
A: ʻO ka maʻamau, e hoʻouna ʻia nā waiwai i loko o 1-3 mau lā hana ma hope o ka loaʻa ʻana o kāu uku.Akā, pili ia i kāu nui.
