Kev piav qhia

Qhov Ib Theem Phab Ntsa Mounted LoRaWAN Hluav Taws Xob Meter no yog lub ntsuas hluav taws xob nrog kev sib txuas wireless, uas yog siv dav los ntsuas kev siv hluav taws xob hauv tsev lossis chaw tsim khoom. Nws cov qauv thiab cov qauv tsim ua tau raws li cov qauv kev lag luam, thiab nws muaj cov yam ntxwv ntawm lub zog txuag, muaj zog tiv thaiv kev cuam tshuam thiab kev ua haujlwm ruaj khov. Ntxiv mus, nws siv LoRaWAN wireless thev naus laus zis los ua kom qhov kev sib txuas lus ntev dua thiab cov teeb liab ruaj khov, uas tuaj yeem ua tau raws li cov kev xav tau ntawm kev sib txuas lus zoo. Tsis tas li ntawd, cov cuab yeej txhawb nqa ob txoj kev ntsuas, uas yog qhov tsim nyog rau kev siv lub hnub ci zog, thiab siv dav hauv nroog, nyob deb nroog thiab chaw ua haujlwm.

Nta

Qhov Ib Theem Phab Ntsa Mounted LoRaWAN Hluav Taws Xob Meter no yog ua los ntawm cov khoom zoo ABS, nrog rau cov plua plav pov thawj thiab dej tsis zoo, yog li nws muaj cov nplaim hluav taws kub thiab tiv thaiv corrosion, yog li nws tuaj yeem siv rau ntau qhov chaw. Nyob rau tib lub sijhawm, nws tau tswj hwm los ntawm ib qho kev xa tawm ib lub tshuab computer, nruab nrog dual channel digital rho tawm chips, thiab muaj kev tiv thaiv hluav taws xob siab thiab cov yam ntxwv tsis tshua muaj hluav taws xob kom ntseeg tau tias siv tau ruaj khov. Tsis tas li ntawd, nws yog txawm peem rau nrog ib tug backlight LCD zaub. Tom qab ib tug thib ob ntawm lub hwj chim rau, tsis muaj peev xwm yuav tsum tau tag nrho tso tawm ntawm lub screen, thiab lub backlight yog nyob rau. Lub cuab yeej tuaj yeem tso saib lub vijtsam tag nrho rau 10 vib nas this los ntawm kev sib txuas lus.
