Relay Module IoT Devices for Remote Controlling of Home Automation System

Remote controlling of home automation system has the potential to help people to control the electronic and home appliance from anywhere. Internet of things (IoT) is proposed to provide the connect and control devices by using the internet network. IoT based switching relays can be used to easily disconnect and connect 220V AC voltage in the home. In this work, ESP8266 microcontroller with relays module to switch and control the home appliances. The internet signal from Wi-Fi is captured by the ESP8266, the microcontroller will send commands according to the instructions from the smartphone remotely. System testing is carried out to determine the performance of the system can work according to design. The three parameters in the system test are the response of the microcontroller to the smartphone application, the response of the relay to the microcontroller, and the response of the electrical device to the relay.
