INFORMATION ON THE DESIGN OF FAILURE COMPLEX DETECTION HOUSE
No full textLack of attention to the developers of housing complexes in the matter of light,causing less terawatnya this facility. Thus we sometimes see in a housing complexthere are some lighting that is not functioning or damaged. If there are no complaintsfrom the residents, will require a long time to fix it or may not be completelyrepaired.Given the problems above, required a lighting failure detection system that canmonitor all the existing lighting at a housing complex. In this case, the authors use the8255 Programmable Peripheral Interface as an interface (interface) as a lightcontroller that uses the Turbo C as software that provides information to the operatortentrang housing complex lighting conditions
DESIGN BY ROOM TEMPERATURE gauge LM35 TEMPERATURE SENSOR USING AT89S51 MICROCONTROLLER
No full textIn writing that I make with the title "Temperature Measuring Equipment Design Room With LM35 Temperature Sensor Using a Microcontroller AT89S51" about design for temperature data acquisition system that uses the basic components of an ADC, temperature sensor, Microcontroller AT89S51 and Seven Segment as a viewer facility. Temperature data acquisition system into the one thing that is very important in industrial activity, because it is a small part of a process control. Regarding the importance of system, so the temperature data acquisition system design that is capable of monitoring the temperature of a plant. The data will be a physical property measured temperature so as to be processed and displayed in the form of electrical systems used LM35 temperature sensor that is able to convert these quantities with the increase of 10mV / º C.To be able to design the system was first carried out the process of changing the temperature into an analog voltage using a temperature sensor LM35. After going through the process was strengthened by the signal conditioning, analog voltage converted into digital data using the ADC 0804. Digital data obtained is then processed by the Microcontroller AT89S51 and displayed, so we get some information about the temperature of the plant unit º C on a Seven Segment From system design, acquisition of temperature data showed that this system has the ability to measure the temperature of 25 º C to 100 º C by the error mean Average temperatures for the appointment of 0.266 ° C
AUTO DOOR SENSOR DESIGN USING INFRA RED

Significantly different wavelengths in the visiblelight between 650 nm and 700 nm. While the infrared ray wavelength is 700 nm and900 nm.Termsuk infrared ray electromagnetic waves. Electromagnetic waves including awave that has medn transfersal magnetic and electric fields rambatnya directionperpendicular to each other.Ease contained in the infra-red can not be seen naked eye, can penetrate theatmosphere, does not require a lot of stress and other causes are used for variousindustrial purposes, commercial and military
EARLY STUDY OF DIGITAL CONTROL SYSTEMS AND INFORMATION AT THE HOUSE FOR AUDIO
No full textThe digital control system will make memorable house was inhabited, althoughabandoned for a few days. This control system worked as long as 24 hours a day bymaking use of changes in light intensity.The digital control tool can be ignited or extinguished in accordance with the desireof user. These tools provide the means to control multiple electrical devices thatignited and extinguished on a certain day such as lighting, television, tape recorder orthe radio. For tape recorders to be used can be filled with an assortment of soundeffects sound like little children crying, the sound the rooster crows, the sound ofsomeone taking a bath and others
GARAGE DOOR CONTROLLER
