style="text-indent:25px">433m無線模塊傳輸距離的影響:1、廠商產(chǎn)品介紹的傳輸距離，是在環(huán)境較好的空曠地嘗試的較準(zhǔn)確的數(shù)據(jù)，客戶買回來使用的環(huán)境干擾比較多，比如樓房墻壁、樹木等。提升傳輸距離的方法：傳輸距離不夠長的時(shí)候，可以挑選一些障礙物較少的地方使用，以此達(dá)到增加距離的目的。2、電源在使用一段時(shí)間后，電壓會減少，導(dǎo)致傳輸距離減少。要想提升傳輸距離，可以更換一個(gè)電容量大電壓穩(wěn)定的電源。3、一些人為了減少傳輸時(shí)間，把433無線模塊的速率提升，導(dǎo)致傳輸距離減少。所以使用的時(shí)候可以把傳輸速率調(diào)低一些，這樣可以增加無線模塊傳輸距離。4、天線是影響模塊傳輸距離的因素之一，高增益天線可以讓距離傳輸更遠(yuǎn)，另外提升天線的架設(shè)高度，盡量保持天線離地面2米以上，這樣可以達(dá)到較好的傳輸距離。</p><p

style="text-indent:25px">433M無線數(shù)傳模塊功能：1.采集功能：采集各類儀表輸出的脈沖量、模擬量或RS232/RS485串口信號。2.存儲功能：本機(jī)循環(huán)存儲監(jiān)測數(shù)據(jù)，掉電不丟失。3.通信功能：采用433MHZ**頻段對外通信，免許可證使用。4.報(bào)警功能：監(jiān)測數(shù)據(jù)越限，立即上報(bào)告警信息。5.對外供電功能：可對外提供直流電源，為儀表/變送器供電。6.遠(yuǎn)程管理功能：支持遠(yuǎn)程參數(shù)設(shè)置、程序升級。433M無線數(shù)傳模塊特點(diǎn)：1.推薦工業(yè)級器件，穩(wěn)定性、可靠性高，適應(yīng)惡劣工業(yè)環(huán)境。2.采用休眠+喚醒的微功耗工作模式，自帶鋰電池組可維持工作時(shí)間＞2年（5分鐘上報(bào)1次數(shù)據(jù)）。3.支持一點(diǎn)對一點(diǎn)、一點(diǎn)對多點(diǎn)的數(shù)據(jù)通信方式。 4.配置筒式密閉防護(hù)外殼，防護(hù)等級IP68，可長期工作在濕度大、污水浸漫的環(huán)境。433MHz無線收發(fā)模組，采用高頻射頻技術(shù)。浙江433mhz無線通訊模塊哪個(gè)牌子好</p><p style="text-indent:25px">一般常用的無線模塊要求的天線阻抗為50歐姆。太原433mhz無線通訊模塊代理</p><p style="text-indent:25px">無線接收模塊的安裝使用：無線發(fā)射模塊建議要垂直安裝在主板的邊緣，應(yīng)離開周圍器件5mm以上，以免受分布參數(shù)影晌。無線收發(fā)模塊的傳輸距離與調(diào)制信號頻率及幅度，發(fā)射電壓及電池容量，發(fā)射天線，接收機(jī)的靈敏度，收發(fā)環(huán)境有關(guān)。一般在開闊區(qū)較大發(fā)射距離約800米，在有障礙的情況下，距離會縮短，由于無線電信號傳輸過程中的折射和反射會形成一些死區(qū)及不穩(wěn)定區(qū)域，無線收發(fā)模塊在不同的收發(fā)環(huán)境會有不同的收發(fā)距離。無線收發(fā)模塊具有芯片體積小，工業(yè)級的設(shè)計(jì)，傳輸速率高窄帶抗干擾性強(qiáng)，接收靈敏度高，功率大，傳輸穩(wěn)定可靠，距離遠(yuǎn)，wifi控制等特點(diǎn)。太原433mhz無線通訊模塊代理</p></p><br
