Nyob rau hauv lub tshav pob ntawm Internet ntawm Yam, tsis muaj ib lub tshuab yuav ua tau tag nrho cov ua lag luam no. Ntau lub thev naus laus zis muaj lawv qhov tsim nyog vim yog qhov sib txawv ntawm kev lag luam xav tau cov ntsiab lus, ntxiv rau ib leeg thiab koom tes. Txawm li cas los xij, qhov tseem ceeb ntawm Bluetooth technology tseem tuaj yeem pom los ntawm peb cov ntaub ntawv tshawb fawb tshiab. Tam sim no, ntawm tag nrho cov IoT thev naus laus zis, tus nqi saws ntawm Bluetooth module technology ranked thawj. Daim ntawv tshaj tawm qhia tau hais tias 38% ntawm tag nrho cov khoom siv IoT siv Bluetooth technology. Qhov kev saws me nyuam no deb tshaj Wi-Fi, RFID, xov tooj ntawm tes thiab lwm yam thev naus laus zis xws li xaim xaim.
Tam sim no muaj ob lub xov tooj cua sib txawv Bluetooth xaiv: Bluetooth Classic thiab Bluetooth Tsawg Zog (Bluetooth LE). Classic Bluetooth (lossis BR/EDR), thawj lub xov tooj cua Bluetooth, tseem siv dav hauv kev siv streaming, tshwj xeeb tshaj yog suab streaming. Bluetooth Tsawg Zog yog tsuas yog siv rau cov ntawv thov bandwidth tsawg uas cov ntaub ntawv nquag kis ntawm cov khoom siv. Bluetooth Low Energy paub txog nws qhov kev siv hluav taws xob tsis tshua muaj zog thiab nws muaj koob meej hauv cov xov tooj ntse, ntsiav tshuaj thiab cov khoos phis tawj ntawm tus kheej.
Thaum qhov loj ntawm ntau yam khoom siv maj mam txo qis, cov yam ntxwv ntawm kev siv hluav taws xob tsawg ntawm Bluetooth ua rau nws muaj peev xwm tswj tau kev ua haujlwm siab ntawm cov khoom siv thiab cov sensors rau lub hlis lossis ntau xyoo nrog tsuas yog lub roj teeb me me, thiab tswj kev ruaj ntseg nrog lwm yam khoom siv.
Tam sim no, Feasycom muaj qhov loj me Bluetooth 5.1 Serial Chaw nres nkoj module FSC-BT691, qhov module no muaj on-board kav hlau txais xov, qhov loj tsuas yog 10mm x 11.9mm x 2mm. Nyob rau tib lub sijhawm, nws tseem yog lub zog siv hluav taws xob tsawg tsawg, siv Dialog DA14531 nti, lub zog noj hauv hom pw tsaug zog tsuas yog 1.6uA.
