style="text-indent:25px">433M無線通信模塊可以應(yīng)用在各種工業(yè)數(shù)據(jù)采集，但是傳統(tǒng)的有線采集方式，會比較不方便，例如:布線困難、環(huán)境復(fù)雜，成本高、費時費力費財?shù)鹊?，但是無線模塊利用無線傳輸方式，可以輕松的解決這些問題，但無線方式也有著一定的弊端，例如:不如有線采集方式來得穩(wěn)定，因為無線采集容易收到天氣等外在因素的影響。無線模塊其它的應(yīng)用領(lǐng)域有很多，比如:農(nóng)業(yè)灌溉、醫(yī)療行業(yè)、智能安防等等，總之，無線模塊會越來越深入人們的生活、工作等等。</p><p style="text-indent:25px">433m無線模塊的天線選擇：433m無線模塊耗低，功能強大，被普遍應(yīng)用于機器人控制，智能家居，無線抄表等領(lǐng)域，產(chǎn)品是工業(yè)級設(shè)計，適用于室外低劣環(huán)境。當(dāng)模塊在使用中發(fā)現(xiàn)距離不夠的時候，經(jīng)常建議選用符合的天線，以達到增加通信距離的目的。那么433無線模塊用哪種天線好?天線是通信系統(tǒng)的重要組成部分，它性能的好壞直接影響通信系統(tǒng)的指標(biāo)，在挑選天線的時候一定要注重其性能，另外天線的增益是天線的重要指標(biāo)之一，它是方向系數(shù)與效率的乘積，是天線輻射或接收電波大小的表現(xiàn)。接收模塊本身不帶解碼集成電路。</p><div

style="text-indent:25px">315M無線模塊和433M無線模塊的對比：315M的波長比433的長些，天線也比433的長些，方向性沒有433M的強，當(dāng)它的繞性好，315M的穿透能力比433M的弱些。433M無線模塊和2.4G無線模塊的對比：2.4G模塊型號傳輸距離短，(一般10~30米，確實通訊距離10米)，傳輸進程衰減大，信號穿透、繞射能力弱，信號輕易被物體遮擋。433M無線模塊信號強，傳輸距離長、穿透、繞射能力強，傳輸進程衰減減小。2.4G和433M是國內(nèi)免許可的ISM(工業(yè)、科學(xué)、醫(yī)學(xué))開放頻段，不需要向當(dāng)?shù)氐臒o線電管理申請授權(quán)，一般國內(nèi)常使用的是433MHz無線模塊。433M無線模塊的集成電路配接時，直接將它們的數(shù)據(jù)輸出端第十七腳接至數(shù)據(jù)模塊的輸入端即可。福州433m無線模塊代理商</p><p
