Low-cost home automation using Arduino and Modbus protocol

Smart home creates the environment that maximizes the quality of life beside the efficient use of energy resources and provides the energy management systems (EMS). Since the energy crisis is a global problem, home automation should be pervasive all around the world as an important component in reducing energy and using renewable energy. One of the fundamental issues in home automation is the cost of automation. Thereby reducing the cost of automation is an important concern in the world. In this paper, a low-cost home automation system based on Arduino microcontroller has been introduced that works with Modbus protocol.
