Measuring rain energy with the employment of “Arduino”
2016
This paper presents the performances of rainfall energy harvesting through the use of a piezoelectric transducer and an Arduino-based measuring system. Diverse studies agree on the possibility of generating electricity from rainfall, but to date, a study that can measure the quantity of energy produced during rainfall is still missing. The present study begins with results obtained from laboratory researchers using piezoelectric transducers and oscilloscopes — to measure the energy produced from a single raindrop — and concludes with an ad hoc Arduino-based measuring system, aimed at measuring the actual amount of electrical energy produced by a piezoelectric transducer that is exposed to r…
FOC with Resolver Implementation for PMSM Drives by Using a Low Cost Atmel SAM3X8E Microcontroller
2020
The aim of this paper is the low-cost experimental implementation of a field oriented control strategy for a Permanent Magnet Synchronous Motor (PMSM) by using an Atmel SAM3X8E microcontroller, mounted on an Arduino DUE board. In this electrical drive for PMSM, a resolver is used in order to measure the rotor position and speed: Therefore, the low-cost Arduino DUE performs not only FOC algorithm and phase currents data acquisition, but also a resolver-To-digital converter process, rotor position and speed data acquisition, and resolver signals management. The code has been implemented in the open source Arduino IDE, using C language, whereas the control and plot visualization interfaces hav…
Conception et réalisation d’un dispositif portatif de capteur de rayonnement PAR
2021
National audience; Dans un contexte de changement climatique et de pratiques agricoles tournées vers la préservation desressources, il devient indispensable de suivre précisément la croissance des cultures pour amener une réponserapide en cas de problèmes (stress, bio-agresseurs…). La croissance des plantes repose sur un processusbioénergétique appelé photosynthèse, elle-même stimulée par le rayonnement photosynthétiquement actif (PAR).Combinée au microclimat, cette grandeur devient également un paramètre essentiel dans certains modèles deprédiction. Cependant les coûts ou la complexité des solutions commerciales (capteurs/centrale d’acquisition) sontdes freins pouvant retarder la compréhen…
A new automated single ring infiltrometer for Beerkan infiltration experiments
2014
A new automated compact device was developed to collect data from single ring infiltration experiment. The infiltrometer consists of a containment ring in which a small quasi-constant head of water (i.e. a few mm) is maintained by a Mariotte reservoir and a very inexpensive data acquisition system, based on the open source microcontroller platform Arduino, and a differential pressure transducer. The design can easily be reproduced and operated. The infiltrometer was tested in a citrus orchard on a sandy loam soil. A simple methodology was applied for an accurate data acquisition from the initial stage of the process and to minimize the disturbance of the soil surface. A new approach to proc…
A measurement setup for electric bicycles powered from renewable energy sources
2014
In this paper a measurement system for a pedalassist rickshaw is described. It has been designed and realized with the purpose of a deep analysis of operating time, range and general performance of the prototype vehicle. The three-wheel velocipede under test, developed in the SDES laboratory of the University of Palermo, is equipped with two battery packs, and a photovoltaic panel which is used to recharge one of the packs at a time. To further improve the autonomy of this mean, a fuel cell will be added as a power source, whose consequent improvement in performance could be easily investigated by the presented measurement setup. An Arduino board has been employed to receive and store all c…

High Performance FOC for Induction Motors with Low Cost ATSAM3X8E Microcontroller
2018
In this paper the Authors present the Arduino Due board application for an induction motor field oriented control (FOC) algorithm. The low cost Arduino Due board is equipped with a ATSAM3X8E microcontroller that performs the algorithm calculation, data processing, current signals and speed/position data acquisition. The control algorithm has been developed with the help of the open source Arduino integrated development environment, whereas a user friendly control interface, used to manage the speed or position set point, has been developed in Java language by means of an other open source software, namely, Processing. An experimental test bed has been set up in order to validate the FOC sys…
