Summary
Wireless home appliance control systems use mobile phones and other hardware to manage household appliances. Students learn how to design and implement such a system, and what its benefits are.
The Problem
Accidents happen when appliances are left on. The system aims to prevent fires and save time. It also helps homeowners check appliance status remotely.
The Solution
