In this study, an internet of things (IoT)-enabled fuzzy intelligent system is introduced for the remote monitoring, diagnosis, and prescription of treatment for patients with COVID-19. The main objective of the present study is to develop an integrated tool that combines IoT and fuzzy logic to provide timely healthcare and diagnosis within a smart framework. This system tracks patients' health by utilizing an arduino microcontroller, a small and affordable computer that reads data from various sensors, to gather data. Once collected, the data are processed, analyzed, and transmitted to a web page for remote access via an IoT-compatible Wi-Fi module. In cases of emergencies, such as abnormal blood pressure, cardiac issues, glucose levels, or temperature, immediate action can be taken to monitor the health of critical COVID-19 patients in isolation. The system employs fuzzy logic to recommend medical treatments for patients. Sudden changes in these medical conditions are remotely reported through a web page to healthcare providers, relatives, or friends. This intelligent system assists healthcare professionals in making informed decisions based on the patient's condition.

There is a growing need for portable, highly sensitive measuring equipment to analyze samples in situ and in real time. For these reasons, it is becoming increasingly important to research new experimental equipment to carry out this work with advanced, robust and low-cost devices. In this framework, a flexible, portable and low-cost fluorimeter (under EUR 500), based on a C12880 MA MEMS micro-spectrometer with an arduino compatible breakout board, has been developed for the trace analysis of biological substances. The proposed system can employ two selectable excitation sources for flexibility, one in the visible region at 405 nm (incorporated in the board) and an external LED at 365 nm in the UV region. This additional excitation source can be easily interchanged, varying the LED type for investigating any fluorophore compound of interest. The measurement process is micro-controlled, which allows the precise control of the spectrometer sensitivity by adjusting the integration time of each experiment separately. Data acquisition is easy, reliable and interfaced with a spreadsheet for fast spectra visualization and calculations. For testing the performance of the new device in fluorescence measurements, different fluorophore molecules which can be commonly found in biological samples, such as Fluorescein, Riboflavin, Quinine, Rhodamine b and Ru (II)-bipyridyl, have been employed. A high sensitivity and low quantitation limits (in the ppb range) have been found in all cases for the investigated chemicals. The portable device is also suitable for the study of other interesting phenomena, such as fluorescence quenching induced by chemical agents (such as halide anions or even auto-quenching). In this sense, an application for the quantification of chloride anions in aqueous solutions has been performed obtaining a LOD value of 18 ppm. The obtained results for all chemicals investigated with the proposed fluorimeter are always very similar in quantification figures, or

The intertidal zone is a harsh environment for marine life as conditions are often both extreme and variable. A wide range of sessile organisms are partially or fully emersed (ex-posed above the water line) during low tide. In the tropics, when corals are emersed, high light and temperature can be detrimental to their survival. To date, there is no commercially-available logger that can detect periods of emersion, information that is use-ful for marine research and for coastal resource management. Here, we present a low-cost arduino-based multi-parameter logger called 'EmerSense' which can detect instances of emersion while simultaneously recording light and temperature profiles. We describe the different steps involved in fabricating EmerSense, including hardware construction and software design, and discuss the results of our field testing at an intertidal coral reef in Singapore.& COPY;2023 The Author(s).

Internet of Things (IoT) is the network of physical objects where data is collected through sensors from the physical world, transferred and handled through the Internet and scientific reactions are put back to real-world finally. As an important application area of IoT, smart home device leads a hot trend to facilitate our daily life and operate with more scientific and rational decisions than the human being. However, targets of the existing smart home devices are rarely animals or pets that involve significantly in modern life, and even less attention is given to uncommon pet varieties such as aquatic animals, amphibians and reptiles. To tackle this issue, this paper proposed a tortoise smart home device as an IoT application example to let pet tortoises enjoy a better living environment and make owners less worried about tortoises' life even if they are away from their pets. Considering habits of tortoises, the tortoise smart home device combines five main functions - temperature, land-water swap, water filtration, feeding and lighting, together with a website for owners' remote control and monitor. Design strategies and implementation details (including versions of arduino microcontroller and different kinds of sensors and actuators) are demonstrated in the paper. Moreover, further ideas about how to easily extend the device and functions applicable for other pet varieties are also brought out.

Vehicular Ad hoc NETworks (VANETs) are likely to play an important role in Intelligent Transport Systems (ITS). Information collected by On Board Units (OBUs) located in vehicles can help in avoiding congestion, provide useful information to drivers, etc. However, not all drivers on roads can benefit from OBU implementation because OBU is currently not available in all car models. Therefore, in this paper, we designed and built a hardware implementation for OBU which allows to disseminate messages in rural areas. This OBU implementation is simple, efficient, and at low cost. Evaluation results show that our proposed model can transmit and receive plaintext and encrypted messages (e.g., safety messages) to nearby vehicles, Access Point (AP), and destination with acceptable time.

Iraqi greenhouses require an active microcontroller system to ensure a suitable microclimate for crop production. At the same time, reliable and timely Water Consumption Rate (WCR) forecasts provide an essential means to reduce the amount of water loss and maintain the environmental conditions inside the greenhouses. The arduino micro-controller system is tested to determine its effectiveness in controlling the WCR, Temperature (T), Relative Humidity (RH), and Irrigation Time (IT) levels and improving plant growth rates. The arduino micro-controller system measurements are compared with the traditional methods to determine the quality of the work of the new control system. The development of mathematical models relies on T, RH, and IT indicators. Based on the results, the new system proves to reliably identify the amount of WCR, IT, T, and RH necessary for plant growth. A t-test for the values from the arduino microcontroller system and traditional devices for both conditions show no significant difference. This means that there is solid evidence that the WCR, IT, T, and RH levels for these two groups are no different. In addition, the linear, two-factor interaction (2FI), and quadratic models display acceptable performance very well since multiple coefficients of determination (R-2) reached 0.962, 0.969, and 0.977% with IT, T, and RH as the predictor variables. This implies that 96.9% of the variability in the WCR is explained by the model. Therefore, it is possible to predict weekly WCR 14 weeks in advance with reasonable accuracy.

In structures with reduced monitoring budgets, the high cost of commercial metering devices is always an obstacle for monitoring structural health. This might be an issue when temperatures must be measured for both structural and environmental reasons. To fill this gap, in this paper, a novel monitoring system is proposed for the accurate measurement of indoor temperature in buildings. This protocol is characterized by its generality, as it can be easily adapted to measure any structural or environmental parameters on site. The proposed monitoring system uses from one to eight low-cost sensors to obtain multiple measurements of the ambient temperatures. The accuracy ranges of the developed monitoring systems with different numbers of sensors are statistically analysed. The results indicate that the discrepancy of the measurements decreases with the increase in the number of sensors, as the maximum standard deviation of 10 sensors (0.42) decreases to 0.32 and 0.27 for clusters of 20 and 30 sensors, respectively.

Traditional wheelchairs which operate manully are difficult to use without the assistance of physical strength. This paper presents a model of an automated wheelchair for disabled people. The proposed wheelchair is battery powered and uses an arduino microcontroller to operate. The whole system consists of two parts, one of them is the sending end and another part is the receiving end. The sender end records instructions from the user's different hand gestures which are collected using an MPU-6050 gyro accelerometer sensor. The instructions are continuously recorded and sent to the receiver end using an RF transmitter-nRF24101 through an arduino microcontroller. At the receiving end, an nRF module receives the signal for mobilizing the wheelchair on a plain surface. Additionally, the device contains a Bluetooth module which can be used as a secondary control system. Hence our chair can be operated by a smartphone application too. Experimental results demonstrate that the proposed model is functional under normal circumstances with a fast response time which can be very useful for disable people to commute with.

IEEE TRANSACTIONS ON INSTRUMENTATION AND MEASUREMENT 2021年 70卷 1页

作者： Bradley, Luke J. Wright, Nick G. Newcastle Univ Sch Engn Merz Court Newcastle Upon Tyne NE1 7RU Tyne & Wear England

A quick, cheap, and portable system for measuring accurately basic electrical characteristics of electronic devices is presented-using common off-the-shelf components linked through a simple breadboard. The system is controlled using a MATLAB app that communicates to an arduino Nano that, in turn, controls two AD5761 16-bit, 20-V, digital-to-analog converters and an INA219 high-side shunt sensor for driving the voltage and measuring the current through a device under test (DUT). The raw data from the system are plotted in real time in MATLAB and are automatically saved to *** file based on the current date and time. For higher current devices (above 10 mA), a simple direct-wired connection between the DUT and the measurement circuit effectively eliminates the breadboard parasitic resistance. With these techniques, the system introduced here shows a negligible difference to the data measured using a Keithley 2410 sourcemeter and a B1500 semiconductor parameter analyzer, thereby presenting a cheap and reproducible alternative to high-end instruments for measuring two- and three-terminal devices.

The oscillation of a bar magnet along the axis of a closed loop solenoid has been studied quantitatively using an ultrasonic sensor and arduino microcontroller-based platform. Real-time displacement of the oscillatory magnet with and without the solenoid shows an additional damping effect due to electromagnetic induction in the presence of the closed-loop solenoid. Variation of the induced current in the solenoid circuit has been analyzed over several cycles by simultaneous recording of the voltage developed across two resistors using ‘analogread’ library function. Energy drained from the oscillator due to electromagnetic damping has been compared with the energy lost in Joule heating of the solenoid circuit. A phase plot for the underdamped oscillator was generated using the fitting parameter values of the curve fitted with the position vs. time data points on the plot. This portable and inexpensive microcontroller-based design is well suited for STEM education of high school and for sophomores in an undergraduate physics course. © 2024 IOP Publishing Ltd.
