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(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(huì)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無線模塊當(dāng)發(fā)射電壓為3V時(shí)，空曠地傳輸距離約20～50米，發(fā)射功率較小，當(dāng)電壓5V時(shí)約100～200米，當(dāng)電壓9V時(shí)約300～500米，當(dāng)發(fā)射電壓為12V時(shí)，為較佳工作電壓，具有較好的發(fā)射效果，發(fā)射電流約60毫安，空曠地傳輸距離700～800米，發(fā)射功率約500毫瓦。當(dāng)電壓大于12V時(shí)功耗增大，有效發(fā)射功率不再明顯提高。這套模塊的特點(diǎn)是發(fā)射功率比較大，傳輸距離比較遠(yuǎn)，比較適合惡劣條件下進(jìn)行通訊。天線建議選用25厘米長的導(dǎo)線，遠(yuǎn)距離傳輸時(shí)建議是能夠豎立起來，因?yàn)闊o線電信號(hào)傳輸時(shí)會(huì)受很多因素的影響，所以一般實(shí)用距離只有標(biāo)稱距離的一半甚至更少，這點(diǎn)需要開發(fā)時(shí)注意。天線駐波比性能好,結(jié)構(gòu)巧妙,安裝方便。</p><div
