RANCANG BANGUN SISTEM PENDETEKSI LEVEL GETARAN MENGGUNAKAN SENSOR GEOFON DENGAN PENAMPIL BORLAND DELPHI 7.0 PADA MONITOR KOMPUTER

Abstract

The research have been succesed plan and relity instrument system of vibration level detector with geophone sensor. The system use to detect eartquake, machine work analize, strongroad analize, multifloor level building structure analize, pipe self frequency, oil and gas exploration, vibration detector, and others. Geophone sensor can detect vibration source and change mechanic vibration to electric power. The sensor gained use buffer circuit and non-inverting op-amp amplifier in order to the output signal that mesured become strong and the data ean be processed by ADC 0804 module. Output data of the sensor by amplifier still in analogue data, becouse the data display in computer so needed an ADC 0804 module that use to change analogue data to digital and system minimum of Microcontroller AT89S51 that have been loaded software to take and send data to computer with RS232 communication protocol as a conector to computer. The result of the research displayed on computer screen as a vibration level graphic which detected by sensor, the recorded data accessed to the language program of Borland Delphi 7.0 and the data can be saved in Microsoft Excel.
