I-Industrial Grade Noise Detection Module Decibel Meter RS485 Noise Sensor TTL Sound Detection Detection Meter

Incazelo emfushane:

1. Faka ukotini wokuhlunga

Sebenzisa imakrofoni ye-polar body capacitor esebenza kahle kakhulu e-back-pole polarized.

2. Ukukhishwa kwephinikhodi okujwayelekile okungu-2.54mm

Iphini ingafakwa ngqo ebhodini lesekhethi lomsebenzisi futhi ingahlolwa ngentambo yeDuPont.

3. Ama-chip angenisiwe asezingeni eliphezulu

Ukunemba okuphezulu kokulinganisa, ububanzi obubanzi, ukuzinza okuhle, ukusebenza okuzinzile kwesikhathi eside.

4. Isakhiwo esihlukile

Ukungena komoya okuhle, impendulo esheshayo, nokulinganisa okunembe kakhudlwana.

Izinhlelo Zokusebenza Zomkhiqizo

Isetshenziswa kakhulu ekulinganisweni kwesikhathi sangempela kwezinhlobo ezahlukene zomsindo endaweni njengomsindo wendawo, umsindo wethrafikhi, umsindo wendawo yokusebenza, umsindo wokwakha kanye nomsindo wokuphila komphakathi.

Amapharamitha Omkhiqizo

Ukudluliselwa okungenantambo
Ukudluliselwa okungenantambo	I-LORA / LORAWAN(EU868MHZ,915MHZ), i-GPRS, i-4G, i-WIFI
Nikeza iseva yamafu nesofthiwe
Isofthiwe	1. Idatha yesikhathi sangempela ingabonakala kusofthiwe. 2. I-alamu ingasethwa ngokwezidingo zakho. 3. Idatha ingalandwa kusuka kusofthiwe.

Imibuzo Evame Ukubuzwa

U: Ngingayithola kanjani ikhotheshini?

A: Ungathumela umbuzo ku-Alibaba noma imininingwane yokuxhumana engezansi, uzothola impendulo ngokushesha.

Q: Yiziphi izici eziyinhloko zale sensor?

1. Sebenzisa imakrofoni ye-polar body capacitor esebenza kahle kakhulu e-back-pole polarized.

2. Ukukhishwa kwephinikhodi okujwayelekile okungu-2.54mm

3. Ukunemba okuphezulu kokulinganisa, ububanzi obubanzi, ukuzinza okuhle, ukusebenza okuzinzile kwesikhathi eside.

4. Ukungena komoya okuhle, impendulo esheshayo, ukulinganisa okunembe kakhudlwana.

U: Ngingawathola amasampula?

A: Yebo, sinezinto ezikhona esitokweni zokukusiza ukuthi uthole amasampula ngokushesha okukhulu.

Q: Iyini i-power supply evamile kanye nokukhishwa kwesignali?

DC4.5~5.5V；I-TTL/0~3V/RS485.

U: Ngingaqoqa kanjani idatha?

A: Ingahlanganiswa ne-4G RTU yethu futhi kuyakhetheka.

U: Ingabe unayo isofthiwe ehambisanayo yesethi yamapharamitha?

A: Yebo, singahlinzeka ngesofthiwe ye-matahced ukusetha zonke izinhlobo zamapharamitha okulinganisa.

U: Ingabe unayo iseva yefu ehambisanayo kanye nesofthiwe?

A: Yebo, singakunikeza isofthiwe ye-matahced futhi imahhala ngokuphelele, ungahlola idatha ngesikhathi sangempela bese ulanda idatha kusuka kusofthiwe, kodwa idinga ukusebenzisa umqoqi wedatha kanye nomsingathi wethu.

Q: Ngingayazi iwaranti yakho?

A: Yebo, ngokuvamile kuba unyaka owodwa.

Q: Isikhathi sokulethwa singakanani?

A: Ngokuvamile, izimpahla zizolethwa ezinsukwini zokusebenza ezingu-3-5 ngemuva kokuthola inkokhelo yakho. Kodwa kuya ngobuningi bakho.

Okwedlule: Inzwa Yomsindo Wangaphandle Yensimbi Engagqwali Inzwa Yemvelo ye-RS485 Yokwakhiwa Kwendawo Yepaki Yendawo Yokuthola Umsindo Imitha Ehlukanisiwe
