A goniophotometer is used to measure the characteristics of any light source such as luminosity. A goniophotometer is used in the design, development and production testing of light emitting diodes (LED), lamps and illuminated signs and in the certification of the final products according to relevant national and international standards. To test the effectiveness of the developed control system, a lab scale model of a goniophotometer was built. The components are two stepper motors, a photoconductive cell light sensor, optical interrupter, power MOSFETS and a Microchip 18F2455 microcontroller. The control system design stage is divided into two major sections, hardware and firmware. The firmware developments involve the PIC 18F2455 programming using the C language. The development of a goniophotometer is important to test any lighting equipment to ensure that they function in fine and safe condition. Corrective measures taken based on the accurate readings made by a goniophotometer can avoid the unwanted problems such as eye damages. This research paper consists of five major parts: introduction, hardware development, firmware development, results and conclusion.","PeriodicalId":443652,"journal":{"name":"2007 5th Student Conference on Research and Development","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114226920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data that has been collected will be analyzed in database to make sure the safety purpose been taken if the water reach to warning level. This project consists of three parts which the first part is involving the development of the system that capable to detect water level. The second part is the development of the system that can process the value that has been collected to the water deepness level. The third part is about the system that will modulate the signal that has been collected from the process system in second part and it will transmit the modulated signal through the antenna. The signal from the third part will be received by the receiver part to be displayed on the display segment. This project used an assembly language for processing part and 7 segment displays for display part. The overall flood detector system design consists of hardware design and software development. The most important hardware design is a microcontroller board that used to control the whole system and the transmitter and receiver module that used to send and collect the data.","PeriodicalId":443652,"journal":{"name":"2007 5th Student Conference on Research and Development","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126128315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The transition is meant from power outlet as the main supply to battery as a backup supply and vice versa. The important requirements during the power-source transition process are to provide supply that is constant, reliable and free from fluctuations. The power supply smooth transition is important especially in electronic devices that utilizing microcontroller and microprocessor. Unstable power transition might create power transients and hence leads to unsynchronized between the processor and other components. This paper explains a circuit design with low-cost and effective method for monitoring and maintaining power supply transition. The purpose of this circuit is to check continuously the level of main supply to a load with a backup supply that will turn on whenever the main supply drops below specified minimum voltage level. When the main supply has reached above the specific minimum level, the control circuit will shut the backup supply and resumes the main supply to the load. The design of this circuit shows that the transition process runs smoothly and eliminates the transients. Although the transition process shows a slight drop in term of voltage supply, the effect does not give significant problem to the target system. It is concluded that the prototype design of this circuit is acceptable and meets the objective of the design.","PeriodicalId":443652,"journal":{"name":"2007 5th Student Conference on Research and Development","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124901100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
