RTOS Based Home Automation System UsingATMEGA

This paper represents the design and implementation of a low cost yet compact and secure RTOS based home automation system using ATMEGA. This design is based on the ATmega328 controller board where the sensors and electrical appliances are connected to the input/output ports of the board. In order to enhance the system performance to make it more dynamic, an open source RTOS has been integrated, which has a built-in power-sense circuit that detects power failures and automatically switches to the backup supply. Devices like light switches, power plugs, temperature sensors, have been integrated in the system to demonstrate the effectiveness and feasibility of the proposed smart home system.
