Faiga faʻavae o le toe faafoiMeaalofa e leai se totogi
Susū mai i Roymall, lau upega tafaʻilagi faʻapolofesa mo le faʻatauina o meaalofa maualuga. Matou te faʻatauaina ma talisapaia lau lagolago, ma matou te fia faʻaalia la matou faʻafetai e ala i le faʻaopoopoina o se lagona fiafia i au faʻatauga. A e faʻatau mai ia i matou, e le gata e te maua oloa maualuga e faʻaleleia ai lou olaga, ae o le a e mauaina foi se meaalofa e leai se totogi i soʻo se oka e te faia. Sauni e suʻesuʻe la matou aoina ma maua au meaalofa lelei? Suʻesuʻe la matou filifiliga o oloa maualuga, fai lau oka, ma faʻatali mo le fiafia o lau meaalofa e leai se totogi e oʻo mai faʻatasi ma lau faʻatauga.Faiga faʻavae o uta
O le a matou galulue malosi e momoli atu oloa ia te oe pe a uma ona maua au oka ma faʻamautinoa e saogalemu le taunuu. O faʻamatalaga o le uta o le a tuʻuina atu i lau imeli faʻamaonia.I le tele o tulaga, o oka e faʻatautaia i totonu o le 2 aso. I tulaga faʻapitoa, o le a tuai e pei ona taua i lalo: A e faia se oka i le Aso Toʻonaʻi, Aso Sa poʻo aso malolo, o le a tuai mo le 2 aso.E masani lava, e manaʻomia le 5-7 aso faigaluega (Aso Gafua i le Aso Faraile) e aunoa ma le aʻafia i le tuai o vaalele poʻo isi mea tau siosiomaga.Talu ai o la matou auaunaga uta o le lalolagi atoa, o taimi o le uta o le a faʻalagolago i lou nofoaga, ma atonu e manaʻomia ai sina taimi ma faʻatali ma le onosaʻi pe afai o loʻo e i totonu o itumalo mamao poʻo atunuʻu.1. Faiga faʻavae o le toe faafoi & fesuiai
Matou te talia na o mea na faʻatau mai roymall.com. Afai e te faʻatau mai a matou tufatufa i le lotoifale poʻo isi faleoloa, e le mafai ona e toe faafoi ia i matou. E le talia le toe faafoi o mea faʻaiʻu poʻo meaalofa e leai se totogi.Ina ia agavaa mo le toe faafoi, e tatau ona le faʻaaogaina lau oloa ma i le tulaga lava e tasi na e mauaina ai. E tatau foi ona i totonu o le uluai afifiina.Ina ua uma ona maua faʻatonuga toe faafoi mai ia i matou, faʻamolemole afifi au mea e toe faafoi ma lafo lau afifi i le falemeli poʻo se isi avefeʻau.O le a matou faʻatautaia lau toe faafoi poʻo le fesuiai oloa i totonu o le 3-5 aso faigaluega pe a uma ona matou mauaina. O le toe totogiina o le a faʻatautaia ma tuʻuina atu otometi i lau auala muamua o le totogiina.E le mafai ona toe faafoi pe fesuiai mea na gaosia faʻapitoa, e aofia ai le lapoa faʻapitoa, lanu faʻapitoa, poʻo le lolomi faʻapitoa.Manaʻomia nisi fesoasoani, faʻamolemole faʻafesoʻotaʻi matou. service@roymall.com poʻo Whatsapp: +8619359849471
2.Faiga faʻavae o le toe totogiina
E te maua se toe totogiina atoa poʻo le 100% aitalafu faleoloa pe a uma ona matou mauaina le afifi toe faafoi ma siaki. O le toe totogiina o le a faʻatautaia ma tuʻuina atu otometi i lau auala muamua o le totogiina.Faamolemole ia matau o tau o uta ma soʻo se tiute poʻo pili e le mafai ona toe totogi. O tau faaopoopo o uta e le mafai ona toe totogi pe a uma ona lafo le afifi. O oe e nafa ma le totogiina o nei pili ma matou te le mafaia ona faʻamagalo pe toe totogi, tusa lava pe toe faafoi le oka ia i matou.Pe a matou mauaina ma faʻamaonia lau mea toe faafoi, o le a matou lafo atu ia te oe se imeli e taʻu atu ai ua matou mauaina lau mea toe faafoi. O le a matou faʻailoa atu foi ia te oe le faʻamaoniga poʻo le teena o lau toe totogi.Afai ei ai ni faʻafitauli e uiga i le faagasologa o le toe totogiina, faʻamolemole faʻafesoʻotaʻi matou. service@roymall.com poʻo Whatsapp: +8619359849471
Description:
n
nWorking Voltage : 5V(DC)
nStatic Current: Less than 2mA.
nOutput Signal: Electric frequency signal, high level 5V, low level 0V.
nSensor Angle: Not more than 15 degrees.
nDetection Distance: 2cm-450cm.
nHigh Precision: Up to 0.3cm
nInput Trigger Signal: 10us TTL impulse
nEch0 Signal : output TTL PWL signal
nMode of connection:
nVCC
ntrig(T)
nech0(R)
nGND
n
nUse Method:
n
nSupply module with 5V, the output will be 5V while obstacle in range, or 0V if not.The out pin of this module is used as a switching output when anti-theft module, and without the feet when ranging modules.
nNote : the module should be inserted in the circuit before been power, which avoid producing high level of misoperation;if not, then power again.
n
nModule Working Principle:
n
n1. Adopt IO trigger through supplying at least 10us of high level signal.
n2. The module automatically send eight 40khz square wave and automatically detect whether receive the returning pulse signal.
n3. If there is signals returning, through outputting high level and the time of high level continuing is the time of that from the ultrasonic transmitting to receiving. Test distance =(high level time * sound (340M/S) / 2.
n
nNote:
n
nThis module is not suitable to connect with electric power, if you need to connect this module with electronic power,then let the GND terminal of this module to be connected first,otherwise, it will affect the normal work of the module
