Abstract

In 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.

Abstract

Series of "Design System Microcontroller Based Digital Queue AT89S51" functionto help create a safe, comfortable and orderly at the time of the queue for a particulartransaction. This tool is designed with Inputan a switch, the data processing usingAT89S51 Microcontroller IC, and output display and buzzer sevensegmen as anindicator of the number of queue detection. This tool works by detecting a pressureswitch Inputan, then microcontroller will process Inputan data input into the next willbe used to perform the counting process and the results will be displayed on theseven-segment indicator with buzzer that sounds. The seven segment displayfunctions provide information to visitors (queue) that the numbers that appear in thesevent-segment display shows the queue number that will make transactions

Abstract

In writing that I make with the title "MOTOR VEHICLE SAFETY DISTANCES USING THE SENSOR ultrasonic microcontroller AT89S51." Meant to reduce the number of motor vehicle accidents, especially for four-wheeled vehicle about to take place every day are happening every day. This happens because not all vehicles have a range of vehicle security system that serves as a warning, if the distance of their vehicles too close to another vehicle. This tool will be placed at the front bunper which will alert you if the distance a vehicle is too close to the vehicle in front.
