With　the　development　of　co　mputer　network　technology,　the　Internet　of　Things　(IoT)　has　also　gradually　begun　to　grow.　Based　on　the　traditional　IoT,　this　paper　proposes　a　lo　w-power　wide-area　Lo　Ra　solution　and　builds　an　IoT　architecture,　including　the　acquisition　layer,　terminal　layer,　application　layer,　etc.,　to　analyze　the　hardware　and　software　design　in　the　architecture.　Finally,　the　future　application　prospect　of　Lora　is　prospected　in　this　paper.　In　general,　the　system　can　g　ive　full　p　lay　to　the　advantages　of　LoRa　technology,　which　will　provide　greater　reference　value　for　the　design　and　development　of　IoT　systems　in　the　future.
