Development of Vibration Detection Prototype Using MPU6050 For Building Durability Evaluation

Abstract

Vibration does not only come from tectonic and volcanic activities, there are also artificial vibrations produced by humans such as construction, transportation, and other industrial activities. Impacts that can be caused by vibration if it occurs consistently such as small cracks. Because every year there is an increase in mobility, it has an impact on infrastructure and industrial development. Especially in high-rise buildings such as office centers where there are many occupants. Vibration can interfere with comfort and health and can even damage the structure of the building has been regulated in ISO 2361: 1997 and ISO 10137: 2007 which regulates related to comfort response and vibration evaluation from human activities. This research aims to develop a prototype that can be used as a measuring instrument to detect vibration so that it can provide information on vibrations received by buildings as one of disaster mitigation. This prototype uses MPU6050, SW-420, and Buzzer sensors and ESP8266 as a microcontroller, the data will be sent to Blynk as data storage and data viewer using Telegram so that people get notification of the amount of vibration that occurs. Testing the prototype by utilizing the massage gun vibration source with the object of a high-rise building mockup, data will be taken on each floor for 15 minutes, and get measurement data on the horizontal axis (x-axis and y-axis). The results of this study found that the vibration of 2100 - 2700 RPM captured acceleration with a range of 0.007 - 0.03 m/s2 still in a small range to be able to demolish the building. The recorded frequency range of 10 - 26 Hz is included in the vibration caused by building occupants with a vibration coefficient of R = 8, namely the area is densely populated and the intensity of activity is high so that it can cause vibration and can be felt by other occupants. So, it can be concluded that the vibration simulation in the developed prototype can be used as a measuring tool and become a disaster mitigation system in high-rise buildings obtaining an average relative error of 6.28% with tool accuracy of 93.72%.
