Abstract

Bluetooth-based and GPS-based object finding systems have become popular in life,but they have their own limitations.Bluetooth has a small search range and cannot find objects accurately in outdoor environment;while GPS has a large search range but it can’t be used indoors.In view of the limitations between Bluetooth and GPS,this article proposes a WiFi-based object finding system.The system has a simple structure and low cost.It uses the ESP8266 WiFi module as the main body.Whether indoors or outdoors, the system can use WiFi network signals and MQTT transmission protocols.Establish a connection with the object-finding device in real time. In addition, CR2032 lithium battery is used to power the finding device, which increases the convenience and battery life of the finding device.
