PEMBUATAN PERANGKAT LUNAK SISTEM TELEMETRI SUHU, KELEMBABAN DAN GAS H2S PADA KAWAH GEOTHERMAL CANDI GEDONG SONGO MENGGUNAKAN JARINGAN Wi-Fi

Abstract

The software of telemetry data acquisition system with temperature, humidity and H2S gas for monitoring the crater geothermal in Gedong Songo temple using Wi-Fi network has been created. Monitoring on three parameters because the crater was steaming hot with H2S gas that can harm humans. This software is used to monitor the condition of temperature, humidity and H2S in geothermal crater Gedong Songo temple. This software made using Borland Delphi 7. Data acquisition from microcontroller to computer through serial communication using CPortLib components. Data transmission system based on the principle of 16-bit serial communications. The program works by reading data bytes temperature, humidity and H2S gas from microcontroller. Data from microcontroller received by the computer and then stored in MySQL database. The software has been created consisting of client and server. Transmission data from the server to client using Wi-Fi network through zeos access components. From the research results obtained by monitoring temperature, humidity and H2S gas is monitored from the server station and client stations. Data from microcontroller is stored in MySQL database. This software is equipped with early warning system alarm when the input data exceeds the value range status and it’s also equipped with facilities to export data in excel file and print the record data directly from the application.
