I-Industrial Grade Detection Module Module Decibel Meter RS485 Noise Sensor TTL Sound Detection Decibel Meter
I-Vedio Yomkhiqizo
Izici Zomkhiqizo
1. Faka ukotini wesihlungi
Yamukela ukusebenza okuphezulu kwe-back-pole polar body capacitor microphone.
2. Okukhipha iphinikhodi okujwayelekile okungu-2.54mm
Iphinikhodi ingafakwa ngokuqondile ebhodini lesekhethi yomsebenzisi futhi ingahlolwa ngocingo lwe-DuPont.
3. Ama-chips angenisiwe asezingeni eliphezulu
Ukunemba okuphezulu kokulinganisa, ububanzi obubanzi, ukuzinza okuhle, ukusebenza okuzinzile kwesikhathi eside.
4. Isakhiwo esihlukile
Ukungena komoya okuhle, ukusabela okusheshayo, ukulinganisa okunembe kakhudlwana.
Izicelo Zomkhiqizo
Isetshenziselwa kakhulu ukulinganisa isikhathi sangempela esizeni sezinhlobo ezahlukene zomsindo ezifana nomsindo wemvelo, umsindo wethrafikhi, umsindo wasendaweni yokusebenza, umsindo wokwakha kanye nomsindo wempilo yomphakathi.

| Nikeza iseva yefu nesofthiwe | |
| Isofthiwe | 1. Idatha yesikhathi sangempela ingabonwa kusofthiwe. 2. I-alamu ingasethwa ngokuvumelana nemfuneko yakho. |
FAQ
Q: Ngingayithola kanjani ikhotheshini?
IMP: Ungathumela uphenyo ku-Alibaba noma imininingwane yokuxhumana engezansi, uzothola impendulo ngaleso sikhathi.
Q: Yiziphi izici eziyinhloko zale nzwa?
A:
1. Yamukela imakrofoni ye-back-pole polar body capacitor esebenza kahle kakhulu.
2. Okukhipha iphinikhodi okujwayelekile okungu-2.54mm
3. Ukunemba okuphezulu kokulinganisa, ububanzi obubanzi, ukuzinza okuhle, ukusebenza okuzinzile kwesikhathi eside.
4. Ukungena komoya okuhle, ukusabela okusheshayo, ukulinganisa okunembe kakhudlwana.
Q:Ngingakwazi ukuthola amasampula?
IMP: Yebo, sinezinto esinazo esitokweni zokukusiza ukuthi uthole amasampula ngokushesha esingakwenza.
Q: Kuyini ukunikezwa kwamandla okuvamile nokuphuma kwesignali?
I-DC4.5~5.5V;I-TTL/0~3V/RS485.
Umbuzo: Ngingayiqoqa kanjani idatha?
A: Ingahlanganiswa ne-4G RTU yethu futhi kuyakhethwa.
Q: Ingabe unayo isofthiwe esethiwe yemingcele efanisiwe?
A:Yebo, singanikezela ngesofthiwe ye-matahced ukusetha zonke izinhlobo zamapharamitha wokulinganisa.
Q: Ingabe unayo iseva yefu ehambisanayo nesofthiwe?
A:Yebo, singahlinzeka ngesofthiwe ye-matahced futhi imahhala ngokuphelele , ungabheka idatha ngesikhathi sangempela futhi ulande idatha kusofthiwe, kodwa idinga ukusebenzisa umqoqi wethu wedatha nomsingathi.
Umbuzo: Ngicela ukwazi iwaranti yakho?
A: Yebo, ngokuvamile unyaka ongu-1.
Q:Sinini isikhathi sokulethwa?
IMP: Ngokuvamile, izimpahla zizolethwa ezinsukwini zokusebenza ezingu-3-5 ngemva kokuthola inkokhelo yakho. Kodwa kuya ngenani lakho.
