ESP 8266 For Control And Monitoring In Smart Home Application

A smart home system is commonly defined as an embedded system in the house which helps residents in carrying out routines at home. In this paper we propose to measuring maximum distance and response time of ESP8266 modules in smart home system which include online and real time controls of: door lock, lighting dimmer, automatic switches equipped with energy sensors, infrared furniture and camera systems. The system modules are based on an ESP8266 Wi-Fi microcontroller. The modules are connected to a central server via Wi-Fi media by using data communication based on JSON on HTTP protocol, using an IP camera. Programs in modules are designed to be as simple as possible to save resources and to achieve the shortest possible response time. Modules on this smart home system have been tested and have proved to operate intelligent-home systems in providing controls of: electricity, automatic door lock, electricity consumption statistics, infrared-based furniture, and cameras to monitor a room directly. Based on experiment the maximum distance between Wi-Fi access points and ESP8266 modules in LOS conditions is 190 meters, and the average response time of the module is 1.62 seconds
