Abstract -- Smart Home is applied in order to provide comfort, energy efficiency and better security. Smart Home System is still rarely used in Indonesia because of the cost and the difficulty of getting the device. The objective of this paper is to offer a Small Smart Home System designed and created by utilizing WLAN network based on Arduino microcontroller. The system is able to monitor and control lights, room temperature, alarms and other household appliances. Results from testing the system show proper control and control monitoring functions can be performed from a device connected to a network that supports HTML5.

I. INTRODUCTION Smart Home is technology to make a house to become

intelligent and automated. Usually, that technology has automation systems for lighting, temperature control, security and many other functions [1]. According to Robles and Kim [2], Smart Home is the term for determining residence using the control system to integrate home automation system. The system allows integrating electronic devices controller with only a few buttons that are connected with the simple telecommunications system. Smart Home includes communications, entertainment, security, convenience, and information systems [3].There are several terms that are commensurate with the Smart Home such as: Home Automation, Intelligent Building or Home Networking.

Since it was first formally introduced by the American Association of House Builders [4], Smart Home drives a lot of research to develop performance, types of controlled equipment and telecommunications systems more reliable. Several studies in the field of Smart Home are as follows. Khiyal Khan, and Shehzadi [5] focused on controlling household appliances to provide security against tampering and provide security when the user is away from the place. The system is SMS based and uses wireless technology. Kaur [6] designed a microcontroller-based Home Automation System which focuses on security that includes password- based locking system, counter-dependent automatic switching system of room, temperature controlled cooling system, saving light systems, fire and smoke sensors. ElShafee and Hamed

[7] presents a new design and prototype implementation of a Home Automation System that uses WiFi technology as a network infrastructure that connects its parts. The proposed system consists of two main parts. The first part is the server which presents the core systems that manage, control, and monitors the user's home. The second part is a hardware interface module. Jin [8] designed and implemented a simulation model of a simple network that is characterized by a network Radio Broadcast Data System (RBDS) and a combination of Zig Bee / IEEE 802.15.4 and Home Plug C & C on Network Simulator Version 2 (NS-2) that supports multiple interfaces / channel. Hamed [9] using Lab View software to monitor temperature, humidity, lighting, fire and burglar alarms, gas density from the house and has an infrared sensor to guarantee the security of the family. This system also has an internet connection to monitor and control the home appliances from anywhere in the world. This approach combines hardware and software technologies. Schaefer and Kays [10] focus on a system, which utilizes good channels and avoids unnecessary overhead, but at the same time is able to use alternative channels in case of a deep fades. The optimal number of channels for the 2.4 GHz range is identified.

Unfortunately, smart home technology is very few adopted in Indonesia. Most are adopted in apartments, residential, and luxury homes. This is because it is very expensive to adopt smart home i.e. for complex telecommunications and control systems and some equipment that are not available in the market. This paper offers a small smart home system to address problems above. The small smart home systems is designed with the Arduino microcontroller-based with WLAN systems, which is able to monitor and control lights, room temperature, alarms for detecting suspicious movements, and other household appliances.

After briefly describing the smart home, the next section of this paper is to discuss design process and parts of the system designed. Several experiments were conducted to test the performance of the system. Finally, this paper will be closed with the conclusion.

II. SYSTEM DESIGN The system was designed by having several blocks,

namely: input/output block, the microcontroller block, networking block and controlling/monitoring devices block. The whole system can be seen in Fig. 1. Detailed explanations of each block are as follows.

INPUT / OUTPUT

MIKRONTROLLER

NETWORKING

MONITORING / CONTROL DEVICE

Fig. 1. Block Diagram of Proposed System

A. Input/Output Block Input/output block consists of two pieces of PIR (Passive

Infra-Red) motion sensor and an LM35 temperature sensor as inputs and some lamps, sockets, relay and buzzer as outputs.

PIR sensor is used to detect the presence of motion. The sensor readings are used to turn off the lights if there is no activity and turn on the lights otherwise. In addition, this sensor is also used for security systems to detect suspicious movements. If it detects any suspicious movement an alarm (buzzer) will sound. An LM35 is functioning as temperature monitoring. This sensor also serves as an input in order to execute some sockets. The socket will in on condition when the temperature exceeds a certain limit. This condition will activate a fan or Air Condition (AC) while connected to the socket. Connection circuit between microcontroller system with a PIR sensor and an LM35 sensor is shown in Fig. 2 and Fig. 3.

B. System Microcontroller The second block is a microcontroller system that serves as

the center of all systems and regulates all activities of the input/output system. The system used in this paper is Arduino. Arduino is a system that uses ATMega 328 as its microcontroller. Arduino consists of an Arduino Board as hardware part and an IDE (Integrated Development Environment) that used C-like as its software language. All devices form input/output and networking block are connected to this. The Arduino system is depicted in Fig.5.

C. Network Block The third is network block that consists of an Ethernet part

and a wireless router device. An Arduino Ethernet Shield is used to connect the Arduino board to the Internet via 3G/4G Wireless Router. Arduino Ethernet Shield is made based on the Wiznet W5100 Ethernet chip which provides the ability to network with TCP and UDP. Ethernet shield is shown in Fig. 6.

D. Monitoring/Controlling Device The last block is monitoring/controlling that consists of

any devices such as: HP, tablet, laptop or PC. These devices connected to LAN or WLAN via network block using HTML5 with two-way communication. The situation and conditions of home based on the sensor readings sent to the monitoring device every two seconds. Status of the equipment that monitored and controlled will be seen in the monitoring device. While the monitoring device able to control appliances at home at any time.

E. Smart Home Designed Fig. 7 shows the implementation of Smart Home designed.

It can be seen that the system has four lamps, two PIR sensors, an LM35 temperature sensor, two sockets and buzzer. All equipment’s placed in each planned place. A scenario has been designed to control all equipment’s. This scenario then was written in C-like Arduino language.
