Simple and efficient electronic energy saving the most is energysaving itself and the second method can be implemented environment-friendly saving which is connected with power management controllers that manage and monitoring power usage. We analyze developed smart controller switch system for five terms: consumption electrical power of controller, sensor response velocity, the accuracy of the number of persons in the room, reliability of packet transmission, and the battery life span. Keywords: smart controller, RF communication, wireless, electronic power 1 Introduction In recent years, the design of efficient energy management system for homes or buildings is an active field of research [1-4]. [5] Proposed a ZigBee-based smart power outlet network for gathering power consumption data. However, the presented energy management system does not provide any protection in an emergency. Based on the ZigBee communication and infrared remote control, Han et al. It can be two ways that hardware or software methods to minimize the power consumption of sensor nodes. The hardware method for the reducing power consumption of sensor nodes can be designed MCU, RF modules, sensors, and in addition to the additional circuitry. It is the block diagram of the circuit of hardware method for sensor nodes of low power configuration. Power facilities are becoming scarcer. Even if they have the power plant facility, the energy is not infinite and the fuel for creating a situation that doesn't have air pollution can also be neglected. To become an annual energy consumption increase rate is 2.8% of the Republic of Korea [6]. 1 Corresponding Author: chojo@dju.kr Tel: , Fax: Dept. of Fire and Disaster Prevention College of Engineering, Daejeon University, Daejeon, Korea ISSN: ASTL Copyright 2016 SERSC

2 In this paper, we analyze efficiency of the developed system in terms of the consumption electrical power of controller, sensor response velocity, the rate of error occurrence (reliability of packet transmission), and battery life span. 1.1 System Design We proposed wireless controller system using RF module [7], the less complexities of an existing wired product, the more simple installation, and the lower costs, too. To develop of the system, there are two main parts: (i) the sensor block which could count sensing the object (human or any kind of animals) and (ii) the controller block that could handle the networked lighting system. 1.2 System Development To analyze of the system we have checked the RF ANTENNA Type, i) The first way of Through Hole manufacture by using dual layer PCB, then connect with pattern ii) The second way of T-pattern connection iii) Finally, we choose the way Attach the left side of the switch Because of the ANTENNA has to be stabilized, the point to be considered, frequency deviation, the anticipated bandwidth is larger than needed bandwidth and all that sort of things. 2 Efficiency Analyses In order to analyze the developed smart controller system, the configuration is as following Table1 and Table2. Table 1. Characteristics of the Electronic Switch Product Model Electronic Switch(PTN300CMA) Fig.1. Switch Inside Size 68(w)*129(L)*22(D) mm Sensing mode Infrared count sensor Operating mode Counter sensor, Power control by moving object Rating AC 220V, 40Hz, 5A Capacity 300W*3 Service power 0.8W Supply method Semiconductor switch Terminals 3 circuits 3 terminals In the process of development smart controller, the parts that matter most is the battery. Because the wireless count sensor uses battery, we have to minimize battery 40 Copyright 2016 SERSC

3 consumption. In order to minimize the battery consumption, we design the sleep mode and active mode. It is sleep mode in the normal state that might consume the minimize current, and it change the active mode when the object comes as near the count sensor. Initial plan was to connect and use in parallel two copies of the four AA batteries, considering a design perspective, but there is the point to be duly considered, the parallel connection is vulnerable to battery life span. Finally we connected in series all battery with more than 6V terminal voltage and added 3.3V voltage regulating circuit. By doing with it, the battery life span is adjusted to be able to extend. By aligning to face of PIR sensor which is located the white area of the prototype, If the object to get within a meter, sensor is changed the mode, active, and then it transmit the data to RF module of Switch. We design the response speed of processing in the RF module of the Switch; as a result, it appeared with no more than 6ms. Table 2. Characteristics of the Wireless Count Sensor Product. Model WLC10D Fig. 2. Sensor Size 68(w)*206(L)*20(D) mm Rating DC 6V(Alkaline Battery (AA)*4) Color White In the state of normal operation condition, Table1 and Table2, we installed the product (electronic switch and wireless count sensor), then we measured the power consumption when the light is ON.

Result Primary attempt 5.32 ms Second attempt 6.00 ms Average 5.66 ms - We deployed the Test JIG with KT Tele cop reliability data. The speed of the back and forth is 30 cycles per minute. In this test, when the object passed by the sensors attached, it evaluates accuracy on the number of times that are transmitted from the signal of sensor to controller. Table 4. The Reliability of Packet Transmission Round Trip No. Error No. Percentage 10, % Fig.5. Test JIG front Fig.6. Test JIG above Fig.7. Test result criteria: one time error occurrence and reliability of the packet transmission We checked the battery life cycle of the wireless count sensor just like equal terms of Table 5. The operating voltage of the wireless count sensor is DC 6V ~ DC 2.7V, if the wireless sensor operates 10 times per one hour, it can be used for one year. And the number of operating cycle is 87,600 times a year (10times*25hours*365days). After 99,999 times operating, evaluating AA voltage was DC 2.73 V. 42 Copyright 2016 SERSC

In the past, that was the kind of switch all equipment had. But most of the electronic equipment today uses an electronic switch that is controlled by a circuit that is always turned on. We developed energy saving smart controller based on RF communication that has the great advantage which reduces the cost of construction as not wasting of resources such as the physical equipment. And in this paper, we evaluate developed controller in respect of five terms: consumption electronic power of controller, sensor response velocity, reliability of packet transmission (it can be also accuracy of the number of persons in the room), and battery life span. As a result, this energy saving smart controller could be commercialized. References 1. D.
