Design of Smart Home System Based on Nb-Iot

Abstract

Abstract In order to solve the problems of high power consumption, complex access network and unstable connection in smart home, a smart home system based on narrowband Internet of things NB-IoT technology is studied. The system uses STM32L431 chip of ST company’s ultra-low power series as the microcontroller, BC95-B5 as the communication module, collects data through a variety of sensors, uploads the collected data information to the remote Huawei cloud server using COAP protocol, and the mobile app accesses the cloud platform and obtains data for display and control. Through the test, the system realizes the function of intelligent control and can greatly improve the intelligent level of home.
