摘　　要：以ESP8266无线网络模块和巴法云开放物联网云平台为基础,设计了一种以ESP8266为控制核心的远程报警系统,利用ESP8266自身WiFi模块实现无线传输,同时利用该芯片实现对DHT11温湿度传感器和MQ-2烟雾气敏传感器的信号采集,采集周围环境温湿度和可燃性气体密度的数据,用蜂鸣器作为报警装置,以LED灯模拟远程控制开关,在巴法云平台或者微信小程序实现了周围环境数据的检测和报警.A remote alarm system with ESP8266 as the control core is designed based on ESP8266 wireless network module and Bafa Cloud open Internet of things cloud platform.The WiFi module of ESP8266 is used to realize wireless transmission.At the same time,the signal acquisition of DHT11 temperature and humidity sensor and MQ2 smoke gas sensor is realized by using the chip.After collecting the data of ambient temperature and humidity and flammable gas density,a buzzer is used as the alarm device and a LED lamp is used to simulate the remote control switch to realize the detection and alarm of surrounding environment data on Bafa Cloud platform or Wechat applet.
