style="text-indent:25px">藍(lán)牙模塊的作用簡(jiǎn)單來(lái)說就是以無(wú)線連接取代有線連接，將固定和移動(dòng)信息設(shè)備組成個(gè)人局域網(wǎng)，實(shí)現(xiàn)設(shè)備之間低成本的無(wú)線互連通信。至于什么是BLE藍(lán)牙模塊，簡(jiǎn)單來(lái)說根據(jù)應(yīng)用和支持協(xié)議劃分，藍(lán)牙主要分為經(jīng)典藍(lán)牙模塊（BT）和低功耗藍(lán)牙模塊（BLE）。經(jīng)典藍(lán)牙模塊（BT）泛指支持藍(lán)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(yǔ)言等。而低功耗藍(lán)牙模塊（BLE）是指支持藍(lán)牙協(xié)議4.0或以上的模塊，就稱為BLE藍(lán)牙模塊，其較大的特點(diǎn)是成本和功耗的降低。應(yīng)用于實(shí)時(shí)性要求比較高，但對(duì)數(shù)據(jù)速率要求不是特別高的產(chǎn)品，如：消費(fèi)電子類（藍(lán)牙低周波按摩器）、可穿戴設(shè)備（手環(huán)、手表、眼鏡）、智能家居（藍(lán)牙鎖、窗簾）醫(yī)療健康類（心跳帶、血壓計(jì)、溫度計(jì)）等。</p><p style="text-indent:25px">BLE藍(lán)牙模塊在心率胸帶上的應(yīng)用：隨著社會(huì)的發(fā)展，人們的生活節(jié)奏也越來(lái)越快，日常的運(yùn)動(dòng)鍛煉也變成了“奢侈品”，怎樣在為數(shù)不多的空閑時(shí)間里達(dá)到更好的運(yùn)動(dòng)效果，也就成為了運(yùn)動(dòng)愛好者們追求的目標(biāo)。想要達(dá)到更好的運(yùn)動(dòng)效果并不是一味盲目地加快鍛煉的頻率或加大鍛煉強(qiáng)度，這樣有時(shí)候反而會(huì)適得其反，造成肌體損傷。較專業(yè)的運(yùn)動(dòng)愛好者都知道，基于監(jiān)測(cè)心率的運(yùn)動(dòng)方式，不僅安全科學(xué)，也能夠有效的提升運(yùn)動(dòng)水平，達(dá)到好的健身塑性的效果。那怎樣很準(zhǔn)的監(jiān)測(cè)心率呢？答案是借助藍(lán)牙心率胸帶。?藍(lán)牙心率胸帶是利用心臟跳動(dòng)產(chǎn)生的微電壓信號(hào)放大處理直接得到心率值，然后通過藍(lán)牙，將數(shù)據(jù)直接傳輸?shù)绞謾C(jī)APP上。通過使用藍(lán)牙心率胸帶能夠監(jiān)測(cè)運(yùn)動(dòng)強(qiáng)度合適時(shí)候的心率，從而避免運(yùn)動(dòng)過度或者不足，助力運(yùn)動(dòng)者更快更科學(xué)的達(dá)到運(yùn)動(dòng)的目標(biāo)。BLE藍(lán)牙模塊可用于樓宇自動(dòng)化、安防、機(jī)房設(shè)備無(wú)線監(jiān)控、門禁系統(tǒng);</p><div

style="text-indent:25px">BLE藍(lán)牙模塊技術(shù)使用與傳統(tǒng)藍(lán)牙技術(shù)相同的自適應(yīng)跳頻(AFH)技術(shù)，因而能確保BLE藍(lán)牙模塊能夠在住宅、工業(yè)與醫(yī)療應(yīng)用中的“嘈雜”射頻環(huán)境中維持穩(wěn)定的傳輸。為了較大程度地減少使用AFH的成本與功耗，BLE藍(lán)牙模塊技術(shù)已將通道數(shù)量從傳統(tǒng)藍(lán)牙技術(shù)的79個(gè)1兆赫茲寬通道減少至40個(gè)2兆赫茲的寬通道。藍(lán)牙技術(shù)、無(wú)線LAN、IEEE802.15.4/無(wú)線個(gè)域網(wǎng)以及許多專有的無(wú)線電均使用無(wú)需認(rèn)證許可的2.4千兆赫工業(yè)科學(xué)醫(yī)療（ISM）頻帶。由于共享這一無(wú)線電波空間的技術(shù)過多，因此無(wú)線性能會(huì)因干擾所引發(fā)的錯(cuò)誤修正與重復(fù)傳送而下降（例如延遲時(shí)間增加和吞吐量減少等）。在要求嚴(yán)格的應(yīng)用中，可通過頻率規(guī)劃與特殊的天線設(shè)計(jì)減少干擾。由于傳統(tǒng)藍(lán)牙與BLE藍(lán)牙模塊均使用AFH這項(xiàng)可以較大程度減少其他無(wú)線電技術(shù)干擾的技術(shù)，因此藍(lán)牙傳輸具有出色的穩(wěn)定性與可靠性。BLE藍(lán)牙模塊，是一種集成藍(lán)牙功能的PCBA板，用于短距離無(wú)線通訊。連云港藍(lán)牙ble模塊4.0廠家供應(yīng)</p><p
