style="text-indent:25px">哪些因素影響無線發(fā)射模塊的傳輸距離以及怎樣提升傳輸距離?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，可以更換一個電容量大電壓穩(wěn)定的電源。3、一些人為了減少傳輸時間，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。無線通信模塊是利用無線技術(shù)進(jìn)行傳輸?shù)囊环N模塊。溫州433m無線收發(fā)模塊商家</p><p
