Psychophysiological measurement can be very crucial in critical conditions faced in aviation, military, hospitals, etc. Respiration rate is one of the primary parameters to determine the psychophysiological condition of a person. An effective respiration rate measurement system is developed using Fiber Bragg Grating (FBG), and a comparison of its response with an electronic sensor is carried out in this paper. An edge filter detection technique is employed to interrogate the optical sensing data. arduino Uno is used for acquiring data from both electronic and optical sensors simultaneously. Both the electronic and optical sensors are fitted inside the same PVC mask, and their responses are compared. The experiment is carried out on five subjects, and every time it is found, that optical sensor is much more reliable and responsive. Optical sensor has better rise and decay constants for instantaneous temperature sensing making it a superior candidate to diagnose various respiration abnormalities. Respiration rate calculation is also carried out during coughing and headshaking. In the events of coughing, response of the optical sensor is much more prominent as compared to the electronic sensor. However, respiration rate calculation remains unaffected and reliable.

A cheap and easy to use arduino self-assembled automatic system was employed to continuously monitor the hydrogen peroxide consumption during the photo-Fenton degradation of caffeine, selected as model target compound. The automatic system made it possible to measure the H2O2 concentration in the reaction cell via a colorimetric reaction and to take samples for HPLC analysis minimising the operator manual intervention and exposure to UV radiation. The obtained results were compared in terms of LOD and LOQ with H2O2 measurements manually performed using UV-Vis spectrophotometry, evidencing better analytical performance when using the automatic system;LOD and LOQ were respectively 0.032 mM and 0.106 mM for the automatic system against 0.064 mM and 0.213 mM for UV-Vis spectrophotometry. Furthermore, the photo-Fenton treatment was optimised by means of a Design of Experiments (DoE) investigating the effect of added H2O2 concentration, iron concentration and caffeine initial concentration on system performances. The use of the automatic device for such monitoring provided several advantages: automation (with consequent reduction of the workload), measurement increased precision, reduced reagents consumption and waste production in agreement with the principles of Green Analytical Chemistry.

Water quality control is essential both before use, to prevent disease, and after use, to prevent the spillage of contaminated water. Although there are sufficient water resources to meet humanity's demand, it is estimated that by 2030 there will be a crisis affecting 40% of the population, therefore it is necessary a proper management of the water resources. While water quality problems exist even in developed countries, poor countries have increasing problems of access to safe potable water, as they do not have the resources to carry out adequate water quality control. For these reasons, it is interesting to apply low-cost and easy-to-build tools to measure or control water quality. In this work it is proposed an arduino-based cost-effective system for the measurement of several parameters involved in water quality, in which compatible sensors have been used to measure pH, conductivity, temperature and turbidity. The model is focused on portability;therefore, it has been designed with a small size. The implementation of an LCD and SD storage allows measurements to be taken on the spot and to be used as a data logger.

The development of programming skills and computational thinking in the formal educational context is one of the most recent horizons set by many educational systems worldwide. Although the first computational thinking initiatives are being applied from the earliest school ages, this research focuses on the secondary education level. Specifically, the objective is the following: to analyse the implementation of arduino, as well as the benefits and opportunities it brings to secondary school students. For this purpose, documentary research has been undertaken applying a systematic review according to the PRISMA 2020 framework following the PiCoS strategy. *** 9 was used to analyse the information. Out of 316 papers identified, 37 were included in the research. In relation to the results, arduino is primarily used in technology and physics subjects, although it is also used to develop interdisciplinary STEAM projects. As a rule, it is used to learn programming languages, but likewise as a resource to develop science experiments. LED lights, servomotors and breadboards are among the most commonly used resources together with the arduino board. and Scratch was the most widely used software. The initiatives implemented have yielded both positive and negative results, for example, one drawback is that some projects are very difficult, and some achievements such as: increased motivation towards the contents addressed or also the development of some soft skills, such as problem solving.

This work presents the design of an open educational low-cost (35 euros) modular and extendable mobile robot based on Android and arduino, with Local Area Network (LAN) and Internet connection capabilities, to be used as an educational tool in labs and classrooms of information and communications technology (ICT) vocational training, or in engineering courses, as well as in e-learning or massive open online courses (MOOC) as an alternative or complementary to virtual labs. It is a first step introducing what we call "BYOR: Bring Your Own Robot" education policy equivalent to "BYOD: Bring your own devices" in computers' world.

Mechanical ventilators are advanced life-supporting machines in this century. The ventilator needs to be safe, flexible, and easy for competent clinicians to use. Since ventilators supply the patient with gas, they need pneumatic components to be present. First technology ventilators were typically powered by pneumatic energy. Gas pressure is used to power ventilators as well as ventilate patients. Nowadays, ventilators are operated electronically with the useful microprocessor tool. This proposal aims to design a simple portable mechanical ventilator that includes measuring some important physiological variables such as respiratory rate, heart rate, and O-2 saturation, which can be utilized in hospital and at home. The proposed system includes arduino, Raspberry pi4, touch screen, and graphical user interface. This study showed a significant individual performance for measuring some important parameters such as flow rate, tidal volume, and minute ventilation. The accuracy of measuring the flow rate was 72%. The Cohen's kappa (CK) was estimated to be 0.61. The accuracy of calculated the tidal volume was estimated at 83% with 0.80 CK. The accuracy of measuring the O-2 saturation was estimated at 99% with 0.99 CK. The advantages of the proposed design are cost-effective, safe, flexible, and easy to use. Also, this system is smart and can control its transactions, so it can be used at home without the need for professional help. The operating parameters can also be set by the user with a simple user interface.
