Approximation of Torricelli's law with Euler's method and an instrumented water tank with ultrasonic sensor

Abstract

In this work, the development of a computer system that has as processing core, an Arduino Nano based board, that collects and processes the signals of a low-cost ultrasonic sensor is presented. The computer system allows monitoring the evolution over time of the height of the water into a container once it begins to empty through a hole in the bottom of it, thus revisiting Torricelli's law with a technological approach using a instrumented container by a computerized electronic data capture and processing data system. The work presents the electrical connection diagrams to interconnect the microcontroller based board and the ultrasonic sensor, as well as the source code used during data acquisition and processing. A comparison of the experimental results is made with results obtained when using the particular analytical solution for the problem, also with the results obtained from implementing the Euler method in obtaining an approximate numerical solution. The presented computer system can be modified and adapted for various academic, educational and research purposes in the various fields of computer engineering, computer systems and mechatronics.

Design of an Intelligent Garbage Container that Allows to Monitor the Waste for its Proper Collection

“…That is why in the present work ultrasonic sensors were used to detect the garbage in the container. [10] The work developed is structured as follows, in section II that belongs to the methodology will be announced about the devices to be used in the system, its operation and the advantage of implementing the system. In the Ill section the results obtained will be discussed and finally in the lV section the conclusion of the project will be argued.…”
