This paper proposed to design a low cost and flexible home prototype system for controlling and monitoring. The proposed design based on two parts; first part, automation system was building by using Arduino UNO microcontroller which responsible on reading and processing the different types of sensor values that's used in the design such as gas leak, flame and temperature as well as the remote control used in automatic garage door. The second part is security system and outdoor lighting the NodeMCU will be used to monitor the state of the house security from anywhere through a special GUI was programming by HTML language that allows the user to monitor the house security as well as extinguishing and operating the outdoor light via specific IP address granted by the NodeMCU. Keywords: Automation house, Smart home, Arduino UNO, House security, NodeMCU 1. Introduction With the increase in population growth and the remarkable increase of factories, the most countries are suffering from the problems of energy conservation and the proper consumption of electricity in this research will address the design of a smart home contributes effectively to energy conservation. Smart house automation technology, lifetime is getting easier and simpler on all side in life. In the world, automatically systems are being chosen over the manual system. With the fast growth in the number of users of the internet through the past decade, the Internet has become a part and section of human life. Home automation gives an individual the ability to remotely or automatically control things around the home. A home appliance is a device or instrument designed to perform a specific function, especially an electrical device, for household use. The words appliance and devices are used interchangeably. Automation is today’s fact, where things are being controlled automatically, usually the basic tasks of turning ON/OFF certain devices and beyond, either remotely or in close proximity (Almali, N., Bahir, K. S., & Atan, Ã. Z., 2017). The main aim of an intelligent house is to focus the control of all the devices into a private control unit which can be programmed to do special tasks suitable for the possessor and the house in question, the aim of a smart home is not only suitability but also to reduce the consuming of resources such as power, gas, etc. Due to the present pricing on energy, energy saving has become a part of a person's day-to-day life, if a person has the possibility to control his home automation, he can remotely reduce the consumption of energy and thus cut down on expenses (David, N., Chima, A., et al., 2015). In the present day, security systems play an important role in the protection of lives and investment. This is achieved by the incorporation of various subsystems into the security system with a single control unit such as surveillance, intruder control, access control, fire detection, etc. A smart home is one that is equipped with lighting, heating, and electronic devices that can be controlled remotely by smartphone or via the internet. An internet-based home automation system focuses on controlling home electronic devices whether you are inside or outside your home (Porter, M. E., & Heppelmann, J. E., 2014). An arduino is a tiny computer that you can program to process inputs and outputs between the device and external components you connect to it. The arduino board is where the code you write is executed. The board can only control and respond to electricity, so specific components are attached to it to enable it to interact with the real world. These components can be sensors, which convert some aspect of the physical world to electricity so that the board can sense it, or actuators, which get electricity from the board and convert it into something that changes
