Aims: Normally, the temperature increase of individuals leads to the possibility of getting a type of disease, which might be risky to other people such as coronavirus. Traditional techniques for tracking core-temperature require body contact either by oral, rectum, axillary, or tympanic, which are unfortunately considered intrusive in nature as well as causes of contagion. Therefore, sensing human core-temperature non-intrusively and remotely is the objective of this research. Background: Nowadays, increasing level of medical sectors is a necessary targets for the research operations, especially with the development of the integrated circuit, sensors and cameras that made the normal life easier. Methods: The solution is by proposing an embedded system consisting of the Arduino microcontroller, which is trained with a model of Mean Absolute Error (MAE) analysis for predicting Contactless Core-Temperature (CCT), which is the real body temperature. Results: The Arduino is connected to an Infrared-Thermal sensor named MLX90614 as input signal, and connected to the LCD to display the CCT. To evaluate the proposed system, experiments are conducted by participating 31-subject sensing contactless temperature from the three face sub-regions: forehead, nose, and cheek. Conclusion: Experimental results approved that CCT can be measured remotely depending on the human face, in which the forehead region is better to be dependent, rather than nose and cheek regions for CCT measurement due to the smallest

AbstractPhotosynthesis research employs several biophysical methods, including the detection of fluorescence. Even though fluorescence is a key method to detect photosynthetic efficiency, it has not been applied/adapted to single-cell confocal microscopy measurements to examine photosynthetic microorganisms. Experiments with photosynthetic cells may require automation to perform a large number of measurements with different parameters, especially concerning light conditions. However, commercial microscopes support custom protocols (throughTime Controlleroffered by Olympus orExperiment Designeroffered by Zeiss) that are often unable to provide special set-ups and connection to external devices (e.g., for irradiation). Our new system combining an Arduino microcontroller with theCell⊕Findersoftware was developed for controlling Olympus FV1000 and FV1200 confocal microscopes and the attached hardware modules. Our software/hardware solution offers (1) a text file-based macro language to control the imaging functions of the microscope; (2) programmable control of several external hardware devices (light sources, thermal controllers, actuators) during imaging via the Arduino microcontroller; (3) theCell⊕Findersoftware with ergonomic user environment, a fast selection method for the biologically important cells and precise positioning feature that reduces unwanted bleaching of the cells by the scanning laser.Cell⊕Findercan be downloaded fromhttp://www.alga.cz/cellfinder. The system was applied to study changes in fluorescence intensity inSynechocystissp. PCC6803 cells under long-term illumination. Thus, we were able to describe the kinetics of phycobilisome decoupling. Microscopy data showed that phycobilisome decoupling appears slowly after long-term (>1 h) exposure to high light.

Wireless Sensor Networks (WSNs) for healthcare have emerged in the recent years. Wireless technology has been developed and used widely for different medical fields. This technology provides healthcare services for patients, especially who suffer from chronic diseases. Services such as catering continuous medical monitoring and get rid of disturbance caused by the sensor of instruments. Sensors are connected to a patient by wires and become bed-bound that less from the mobility of the patient. In this paper, proposed a real-time heart pulse monitoring system via conducted an electronic circuit architecture to measure Heart Pulse (HP) for patients and display heart pulse measuring via smartphone and computer over the network in real-time settings. In HP measuring application standpoint, using sensor technology to observe heart pulse by bringing the fingerprint to the sensor via used Arduino microcontroller with Ethernet shield to connect heart pulse circuit to the internet and send results to the web server and receive it anywhere. The proposed system provided the usability by the user (user-friendly) not only by the specialist. Also, it offered speed andresults accuracy, the highest availability with the user on an ongoing basis, and few cost.

In Indonesia, the number of death of accident is still pretty high with most of 70% the traffic accident is motorcycle driver who is late in getting aid and the head injury is the first order of all types of experiencing by the accident victim. Prehospital Care is an emergency service when the victim is firstly found, during the process of the transportation until the patient arrives at the hospital Thus, the purpose of this research is the application of GPS (Global Positioning System) and SMS gateway on the safety helmet in order to increase the aid post-accident. The application of GPS has an advantage to receive data from the satellite which next will be stored on arduino microcontroller. Microcontroller will retrieve the driver location data in the forms of latitude, longitude and time. Next, the driver location will be sent by microcontroller via SMS gateway service to the nearest hospital and the victim's family to make the evacuation process easy. This research is tested along the travel of Jember-Lumajang regency. The result of this research is the GPS application on the safety helmet can be applied well. The transmission of driver position coordinate data if the accident happened via sending media of SMS can be applied along with GSM signal from the provider so that the SMS sending works well.

This paper presents a relatively new concept for the design and implementation of a grid-tie inverter for photo voltaic (PV) systems. The proposed method will eliminate the uses of battery pack hence overall cost of any PV project will be significantly reduced. As the output of any PV array varies with the variation of solar irradiance hence a boost converter with PID regulated variable duty cycle has been used to keep a constant input to the inverter. Multilevel inverter topology has been proposed for utility grid connectivity. The proposed design is simulated in MATLAB/Simulink and a prototype is also implemented to verify the simulation results. The controllers are implemented in Arduino microcontroller board.

Pada perkembangan teknologi sekarang, khususnya di bidang microcontroller arduino telah banyak menciptakan berbagai macam project yang dapat menyelesaikan permasalahan dalam kehidupan sehari-hari. Kemudian microcontroller arduino, menjadi salah satu pilihan solusi yang ada pada saat ini. Seperti permasalahan yang diangkat pada penelitian ini. Ketika terjadi cuaca tidak menentu dan diharuskan setiap hari untuk mencuci pakaian kemudian menjemur di area terbuka, maka akan sangat merepotkan apabila terjadi hujan. Oleh karena itu diperlukan peran teknologi microcontroller untuk membantu menyelesaikan permasalahan yang tersebut. Yakni dengan cara membuat penjemur pakaian otomatis yang berbasis microcontroller arduino, serta penambahan metode Naïve Bayes yang dapat menghitung klasifikasi data yang berisi nilai intensitas cahaya dan kelembapan udara. Data tersebut diperoleh dari hasil pengambilan selama 1 minggu dengan kondisi cuaca yang tidak menentu. Data tersebut akan membantu dalam proses pengambilan keputusan pada motor penggerak yang digunakan. Penjemur pakaian akan bergerak keluar dan kedalam sesuai dengan perintah yang telah diproses hitung dengan menggunakan metode Naïve Bayes pada arduino. Hasilnya algoritma Naive Bayes mampu memberikan keputusan 100% akurat bila dibandingkan dengan algoritma if/else yang hanya menghasilkan 50% keputusan akurat. Diharapkan dengan adanya penjemur pakaian otomatis ini, akan menjadi solusi dari permasalahan yang ada pada saat ini.Kata Kunci: arduino, microcontroller, naïve bayes, sensor LDR, sensor DHT 11
