I. INTRODUCTION

Nowadays, communication technology has been widely developed. Thus, there is new technology emerged to easily communicate, i.e. Wi-Fi, 3G, 4G, and so on. People around the world can easily interact with each other because there are communication networks installed in all areas: enterprises, department store, public places, and homes. Generally, the communication networks are allowed to access all times in term of convenience and easy usage. In addition, the communication networks can be used to send data as control signal.

Bahtiyar et al. [1] present a framework to assess trust to security systems of web services. The framework is used to improve an automated system to assess trust of a specific security system protecting web services. Zhaozheng et al. [2] investigate a set of Internet service security system. RFID technology, GSM communication technology, and LCD display are studied by Pinggui et al. [3]. The results indicate that the proposed security can effectively prevent campus safety accidents.

proposes the design of an Automated Office receptionist system using Raspberry Pi 3 and an Android Application. The proposed system can eliminate manual assistance and also improve the security with simple devices and low costs. Tanwar et al. [5] present a security alert system based on advanced Internet of Thing to detect an intruder or any unusual event at home. A small Pyroelectric Infrared (PIR) module and raspberry pi are used to reduce the delay during process. Thus, the proposed technique is low cost for a home security system and flexible usage. Kaliyamurthy et al. [6] investigate combination of user and system interaction, whole together in the course of providing efficient secured network using multilevel system and user intervention which in turn reduces the system or the user's possibility of false perception in securing the network. The physical network environment threat data is analyzed as a Decision Support System.

Communicative technology is applied to the easily accessible safety systems of life and property. Thus, communicative technology which is an internet network is developed to use as monitor and notification systems using a microcontroller to control and detect. Additionally, when the communicative technology is cooperated with a designed software program, it can be alerted through the user's computer. This paper presents a security system uses smoke sensors, motion sensors, and magnetic sensors to detect environment conditions, using a microcontroller to control system operation. The output from the devices is used as raw data and then sent to process with a created program. The program will send signal to operate the alarm system and it can operate on the designed webpage.

The central computer is used to be an interface and processing of the proposed system. The Delphi software is used to control the devices using a microcontroller, which receives raw data from sensors via a serial communicate system. In addition, the status of the devices is displayed through a web page created from the PHP program. System operation is divided into two parts: hardware and software as shown in Fig. 2.

Hardware Software

Figure 2. The box diagram of the designed security system.

A. Hardware Part

Hardware consists of 8 relays and 3 sensors (a smoke sensor, micro switch, and a motion sensor), which is connected to the microcontroller. The raw data from the devices is sent via serial ports and recorded as database on the computer in order to process, control, and alert the security system automatically.

1) Relay. Fig. 3 shows the circuit diagram of a relay. When the relay’s coil is energized by electricity, a magnetic field will be occurred, resulting in movement of the movable contracts making a connection with a fixed contact, hence an electric current flow. Additionally, there are LED lamps to indicate the status of relays.

2) Motion. The motion sensor used is an infrared type, consisting of a transmitter circuit and a receiver circuit as shown in Fig. 4. When there is no an obstacle, the receiver circuit will not generate output signals. By contrast, if the sensor able to detect an object, there are signals generated from the output.

3) Motion. The smoke sensor circuit is shown in Fig. 5. When there is smoke occurring around the detected areas, the infrared light inside the sensor will be covered. Therefore, T1 and T2 transistors based on a Darlington connector will operate. The gate voltage of the SCR (T3) is high, causing voltage drop the MOSFET at T4 via the R4 resistance, thus BZ1 and LED lamps are activated.

4) ATmega64 microcontroller. A microcontroller is used to control all functions of the designed security system based on communication technology. In case study, the ATmega64 microcontroller of 64 pin is selected as shown Fig. 6.

IV. CONCLUSION

This paper presents the security system based on communication technology, dividing into two parts: the device control (relays and sensors) and the notification system on a webpage. In part of device operation, all of delays can operate ON-OFF effectively. There is LED display to indicate the status of the relays (0 or 1). The status for the sensors is ON-OFF, which works well together with the control system. For the notification, the status of three sensors is shown in the designed webpage on the server computer. If a fault takes place with the installed sensors, there is alarm on the webpage — ON status is shown. Thus, all installed sensors and the notification system can work realizable and effectively.
