Using Mobile Phone to Control Remotely Electronic Devices in Smart Home System

Abstract

Introduction. Smart Home technology encompasses a range of intelligent devices designed for residential use. These devices present numerous opportunities to transform our lifestyles in the future. Smart Home technology has made significant contributions to enhancing safety and reliability while potentially altering our daily habits. In contemporary society, mobile phones serve purposes beyond mere communication. As technology evolves, the functionality of mobile phones expands, allowing them to be utilized for various applications. Currently, a wide array of applications and hardware is available in the market that can be integrated without necessitating further advancements in existing smartphones. Through network connectivity, mobile phones can facilitate the management of smart home systems, enabling users to control devices and receive alerts regarding potential theft or unauthorized access. The purpose of the paper is to establish a smart home system that allows for remote control of electronic devices and provides notifications of intrusions or movements in restricted areas. The devices are managed via mobile phones using the Short Message Service (SMS), with alerts also sent as SMS messages detailing activities occurring within the vicinity. Results. A smart home system was developed that allows remote control of household electronic devices using a mobile phone. Control of the devices was facilitated through the transmission of instructions via SMS, with alerts also being delivered in the same manner. A Hall Effect proximity sensor was employed to detect unauthorized entry, while a passive infrared sensor was utilized to monitor movement in restricted zones. Additionally, a temperature sensor functioned as a heat detector, and an LED light was incorporated to demonstrate the management of electronic devices. The Arduino Uno Board served as the microcontroller, and the SIM900 GPRS/GSM module was utilized for communication between the microcontroller and the mobile device. Notably, the mobile phone did not require any specialized applications or hardware; any mobile phone capable of sending and receiving SMS could function as a mobile station. Conclusion. Thus, the developed Smart Home system demonstrated its effectiveness. The microcontroller unit effectively responds to commands issued by the mobile phone, adapting to the application's requirements and activating an alarm in critical situations. Additionally, the application successfully facilitates the remote management of electronic devices.
