Development of Liquefied Petroleum Gas (LPG) leakage detection wheeled robot on horizontal pipes based on Arduino Uno

摘要

Abstract LPG utilization need more attention to safety aspects of human, environmental and equipment. This research aims to develop a wheeled robot which is capable of detecting LPG leaks in horizontal pipes by data acquisition via wireless internet, so that it is useful to facilitate human work in determining LPG leak points on horizontal pipes. The controller of this robot is Arduino UNO and equipped with sensors. The sensor measurement data is acquisitioned using the Node MCU module to the Blynk application as an interface application. This robot has an emergency stop feature on the Blynk application. The final results of this research are LPG leak detection robots on horizontal pipes which can provide information on leak points based on gas sensor measurement data and rotary encoder installed on robots with acquisition via wireless internet and data storage on MicroSD. The robot is equipped with buzzer indicator that will sound when a leak is indicated with a gas concentration of more than 30% on one of the gas sensors. Based on the results of final test of the robot, the average value of the leakage point distance obtained is +8.7 cm.
