Huahana Vedio
Nā hiʻohiʻona huahana
1. E hoʻouka i ka pulupulu kānana
Hoʻohana i ka hana kiʻekiʻe prepolarized back-pole polar body capacitor microphone.
2. 2.54mm maʻamau pin output
Hiki ke hoʻokomo pololei ʻia ka pine i ka papa kaapuni o ka mea hoʻohana a hiki ke hoʻāʻo ʻia me ka uea DuPont.
3. Kiʻekiʻe kiʻekiʻe i laweia mai
ʻO ka pololei ana kiʻekiʻe, ka laulā ākea, ka paʻa maikaʻi, ka hana paʻa lōʻihi.
4. Hoʻokaʻawale hale
Maikaʻi ea permeability, wikiwiki pane, oi pololei ana.
Nā noi huahana
Hoʻohana nui ʻia no ke ana ʻana i ka manawa maoli o nā ʻano leo like ʻole e like me ka walaʻau kaiapuni, ka walaʻau kaʻa, ka walaʻau wahi hana, ka walaʻau kūkulu a me ka walaʻau ola.

FAQ
Q: Pehea e hiki ai iaʻu ke loaʻa ka ʻōlelo?
A: Hiki iā ʻoe ke hoʻouna i ka nīnau ma Alibaba a i ʻole ka ʻike pili i lalo, e loaʻa iā ʻoe ka pane i ka manawa hoʻokahi.
Nīnau: He aha nā hiʻohiʻona nui o kēia sensor?
A:
1. Adopt high-performance prepolarized back-polar kino capacitor microphone.
2. 2.54mm maʻamau pin output
3. ʻO ke ana kiʻekiʻe, ākea ākea, kūpaʻa maikaʻi, hana paʻa lōʻihi.
4. He maikaʻi ka ea permeability, pane wikiwiki, ke ana pololei.
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?
DC4.5~5.5V；TTL/0~3V/RS485.
Nīnau: Pehea e hiki ai iaʻu ke hōʻiliʻili i ka ʻikepili?
A: Hiki iā ia ke hui pū me kā mākou 4G RTU a he koho.
Nīnau: Loaʻa iā ʻoe nā polokalamu hoʻonohonoho i hoʻonohonoho ʻia?
A: ʻAe, hiki iā mākou ke hāʻawi i ka polokalamu matahced e hoʻonohonoho i nā ʻano ʻano ana.
Nīnau: Loaʻa iā ʻoe ke kikowaena kapua a me ka lako polokalamu?
A: ʻAe, hiki iā mākou ke hāʻawi i ka polokalamu matahced a manuahi ʻole, hiki iā ʻoe ke nānā i ka ʻikepili i ka manawa maoli a hoʻoiho i ka ʻikepili mai ka polokalamu, akā pono ia e hoʻohana i kā mākou ʻohi ʻikepili a me ka mea hoʻokipa.
Q: Hiki iaʻu ke ʻike i kāu palapala hoʻokō?
A: ʻAe, maʻamau he 1 makahiki.
Q: He aha ka manawa hoʻouna?
A: ʻO ka mea maʻamau, e hāʻawi ʻia nā waiwai ma 3-5 mau lā hana ma hope o ka loaʻa ʻana o kāu uku. Akā, pili ia i kāu nui.
