Customizable Digital Control System for Domestic Application with IoT Capability

Abstract

In this era, digitization and automation has made the life of human beings simpler. Automation saves money, time, and reduces the human efforts. Traditional appliances control systems are less reliable, require more human effort, and lag from safety measures. We designed a sophisticated but very intuitive and low-cost mechanized touch screen control panel system for home appliances and security with the Internet of Things (IoT) capability. This work includes a standard web server and Wi-Fi technology to control the home appliances. The appliances can be switched ON and OFF through an Android device and touch screen board mounted on the wall. To control the speed of a fan, a TRIAC-based digital dimmer has been designed. The concept is based on controlling the ON time of TRIAC to control the AC power of the fan. Furthermore, different sensors, e.g., Temperature, Humidity, and Voltage have been deployed for security reasons that take the values and display them on the android device. The ESP8266 module with microcontroller and Wi-Fi capability has been used for wireless control of appliances. Similarly, ESP8266 takes the data from sensors and transmits it to the server using the client-server protocol. Each appliance is connected with an ESP8266 and one ESP8266 is connected to touch modules through a client-server connection. We aim to make the interface look very presentable, efficient, customizable, and user-friendly.
