SISTEM ANTARMUKA SENSOR JARAK INFRAMERAH DAN APLIKASINYA UNTUK PENGUKURAN LEVEL AIR

Abstract

This research makes the hardware and software of computer-based measurement of the water level. This device can be used as a monitoring system for water tank charging to utilize water as a booster pump water from a reservoir to the water source and water tank automatically, so that the water filling can be regularly and timely. Infrared sensors detect a series of buoys in the pipe height by emitting infrared light and then detecting reflections. Infrared light received by the sensor will be processed to produce the output of the analog voltage. Filling the water tank using the RS-232 serial communication between the microcontroller ATmega8535 and computer software applied with Borland Delphi 7.0. This system sends the data sent by the computer and received by the microcontroller. The computer will send the data to the mikrokontroler to provide water tank filling time interval in accordance with specified. The data transmission to turn on and turn off the pump. Selainitu, the computer also sends data to two tubs charging is appropriate, in accordance with the predefined settings. From water level system testing showed that the system created has the characteristic height of the ADC made y = -3,087x + 297,2. Data will be saved to Borland Delphi and displays in graphical form and display the data in tabular form. Keywords: water level gauge, RS-232, Delphi, Microcontroller ATmega8535.
