PEMBUATAN SOFTWARE SISTEM KONTROL TEKANAN UAP DALAM TANGKI MENGGUNAKAN MIKROKONTROLLER ATMEGA 8535 DAN SENSOR MPX5500DP BERBASIS BORLAND DELPHI 7.0

Abstract

In this research, the manufacture of steam pressure control system software using MPX5500DP vapor pressure sensor that functions as a sensor to detect the vapor pressure. This control system is used for a tea company, which aims to lighten the work of employees and minimize accidents in the workplace. The application program is displayed on a computer created using Delphi 7.0 program that serves to detect the vapor pressure sensor using MPX5500DP. The sensor will read the pressure using a microcontroller ADC. ADC value that has been generated by the microcontroller is sent to the computer using a USB cable to Serial Converter. The program has created a system of microcontroller ADC readings are sent using Delphi serial communication so that the program will show the vapor pressure in the tank. Automatically heater will die when it reaches the specified setpoint as well as the solenoid will turn on automatically when it reaches the setpoint which has been set. From the test results in getting this tool is very helpful with the system designed is able to measure, monitor, and control the water temperature.
