Real-time data acquisition of dynamic moving objects

Abstract

The problem frequently encountered in physics practicum activities is measuring instruments in limited reading data variable time of dynamic moving objects. In practical exercises needed the accuracy of measurement data to avoid a mistake in analysis and interpretation data. R-TDA of Dynamic Moving Objects measurement tool is expected to be a solution to overcome these problems. The electronic components used are Infra-Red Obstacle Sensor, connector cable, NodeMCU. The principle of this device is to send a recording time of modulo infrared to the cloud server and accessed via a smartphone and Personal Computer. The results show the sensor a responsive time of 6.8 x 10-11 seconds, and the effect of gravity acceleration of 9,70 m/s2 close to universal gravity acceleration 9,81 m/s2 with an average relative error of 1.22%. The R-TDA of Dynamic Moving Objects has a high response time and accuracy in recording the time of dynamic moving objects.
