This document presents a smart home automation and security system based on the MSP430 microcontroller that uses Wi-Fi technology. The system allows users to control home appliances either manually or automatically based on sensor readings. Sensors like temperature, soil moisture, light, and smoke sensors are used to monitor conditions and control appliances accordingly. A web interface is also provided to access sensor data and appliance status remotely. The system aims to automate home tasks like irrigation and provide convenience and security.
