WIRELESS HOME AUTOMATION SYSTEM BASED ON MICROCONTROLLER

This paper presents the development of Global System Mobile (GSM)-based control home air-conditioner for home automation system. The main aim of the prototype development is to reduce electricity wastage. GSM module was used for receiving Short Message Service (SMS) from the user’s mobile phone that automatically enable the controller to take any further action such as to switch ON and OFF the home air-conditioner. The system controls the air-conditioner based on the temperature reading through the sensor. Every period temperature sensor sends the degree to Micro Controller Unit (MCU) through ZigBee. Based on temperature degree MCU send ON or OFF signal to switch. Additionally, system allows user to operate or shut down the airconditioner remotely through SMS
