RANCANG BANGUN SISTEM MONITORING SUHU DAN KECEPATAN ANGIN PADA SISTEM KLIMATOLOGI MENGGUNAKAN MIKROKONTROLER AT89S51

Abstract

The appliance of climate system that monitoring parameters like temperature, humidity,wind direction and wind velocity based on Microcontroller AT 89S51 and the displayed on a computer used Borland Delphi 6 has been realized. This system can be used in various aspect like air transportation, navigation, hankam, communication, and etc. This system uses 4 sensors that each of them has different function. Temperature sensor uses LM 35 that worked by concert temperature to voltage. To know the wind direction and wind velocity, uses optocouplers. And to know the humidity, uses humidity sensor HS15P that convert humidity to voltage. Processed system uses IC Microcontroller AT 89S51 that programmed by assembly Reads 51. The datas are interfaced to computer with Borland Delphi 6 as a visualization and it has been saved on a hard disk. This system have 4 windows by its interfacing. They are visualization of temperature, humidity, wind direction and wind velocity. Every data from the reading will be saved on a MSExcel. Interfacing software also completed by time indicator and graphic.
