style="text-indent:25px">BLE藍牙模塊屏蔽罩的作用：手機、GPS、無線模塊電子產(chǎn)品的主板很多元件上方都焊有由金屬支架和金屬蓋組合在一起起到屏蔽作用的屏蔽罩。目前，藍牙模塊上使用一體式屏蔽罩比較多，簡單性價比高，在PCB板上屏蔽靜電等對電子元件起保護作用。?屏蔽罩的原理：用屏蔽體將元部件，電路，組合件，電纜或整個系統(tǒng)的干擾源包圍起來，防止干擾電磁場向外擴散;用屏蔽體將接收電路，設備或系統(tǒng)包圍起來，防止它們受到外界電磁場的影響。要想提升無線控制距離，單純追求高靈敏度或者增加發(fā)射端的發(fā)射功率不能完全增加控制距離，因為在實際應用中會有供電、工作環(huán)境中的電磁干擾或者電源紋波干擾等因素存在，因此要綜合考慮RF接收端各類抗干擾能力。在BLE藍牙模塊上，應選擇合理的元器件，特別是選擇硬件抗干擾方法的過程中。</p><div

style="text-indent:25px">隨著物聯(lián)網(wǎng)時代的到來，無線傳輸也變得越來越重要，其中無線模塊就是一個典型的例子；因為物與物之間想要進行溝通，就需依靠無線通訊模塊幫助他們實現(xiàn)對訊號的發(fā)送與接收，使各類物聯(lián)網(wǎng)終端設備都具備聯(lián)網(wǎng)訊息傳輸能力。無線模塊在遙控、遙測、無線遙控系統(tǒng)、安全防火系統(tǒng)、小型無線網(wǎng)絡、工業(yè)數(shù)據(jù)采集系統(tǒng)、無線吊稱、無線電子衡器、車輛監(jiān)控、不停車收費、停車場管理、無線標簽、身份識別、生物信號采集、水文氣象監(jiān)控、機器人控制、數(shù)字音頻傳輸?shù)榷紩婕?。那么其中無線模塊中的BLE藍牙模塊又有何特點呢??具備抗干擾能力：抗干擾能力強，可滿足不同無線通訊環(huán)境。多連接功能：藍牙可以同時連接多種設備，主模式的時候可連接多個從模塊?！LE藍牙模塊高效的多路徑優(yōu)勢增加了鏈路預算和有效的運行范圍，同時也優(yōu)化了功耗。溫州哪里有藍牙集成模塊</p><p style="text-indent:25px">BLE藍牙模塊芯片極小，可以直接嵌入數(shù)字電表中。溫州哪里有藍牙集成模塊</p><p style="text-indent:25px">藍牙模塊的作用簡單來說就是以無線連接取代有線連接，將固定和移動信息設備組成個人局域網(wǎng)，實現(xiàn)設備之間低成本的無線互連通信。至于什么是BLE藍牙模塊，簡單來說根據(jù)應用和支持協(xié)議劃分，藍牙主要分為經(jīng)典藍牙模塊（BT）和低功耗藍牙模塊（BLE）。經(jīng)典藍牙模塊（BT）泛指支持藍牙協(xié)議在4.0以下的模塊，一般用于數(shù)據(jù)量比較大的傳輸，如：音樂、語言等。而低功耗藍牙模塊（BLE）是指支持藍牙協(xié)議4.0或以上的模塊，就稱為BLE藍牙模塊，其較大的特點是成本和功耗的降低。應用于實時性要求比較高，但對數(shù)據(jù)速率要求不是特別高的產(chǎn)品，如：消費電子類（藍牙低周波按摩器）、可穿戴設備（手環(huán)、手表、眼鏡）、智能家居（藍牙鎖、窗簾）醫(yī)療健康類（心跳帶、血壓計、溫度計）等。溫州哪里有藍牙集成模塊</p><p
