Mobile Application for IoT-Based Smart Home System for Appliance Control and Fire Alert

Smartphones played a significant role in our daily lives, especially during the pandemic when everyone was stuck at home. We use it to communicate with others, entertain ourselves, order food, shop around, etc. However, this device is also useful for automation and centralizing control of our homes. This study focuses on developing a mobile application for an IoT-based smart home system capable of controlling appliances and alarming in the presence of fire and gas leaks. The researchers used a free web application creation tool called MIT App Inventor to build the application and its features. Also, a cloud-hosted database, Firebase, was used to connect the application to the smart home system. The final product of the study was a mobile phone application for Android devices capable of turning appliances on or off and acting as an alarm when a fire or gas leak was present in the house.
