Access to health remains a real problem in Africa especially for the follow up of patients with chronic diseases. Many cases of heart attack deaths are still recorded before victims can access treatment. This is due to several factors, namely the insufficient number of cardiologists, the inaccessibility of hospitals with adequate infrastructure, the carelessness and ignorance of people about their health. In response to these limitations, internet of Things, thanks to its remarkable technological contribution, allow to follow from afar and easily patient's condition. In this paper, we offer a ubiquitous surveillance solution distance from patients with cardiovascular disease in order to minimize or eliminate the risk of heart attacks. The proposed solution is based on a microservice architecture and consists of two essential parts that are data acquisition and data transfer. It will allow the patient to access their physical data and submit them in real time to the doctor through a dedicated medical application. The doctor will then be able to analyse the data obtained and return a prescription to the patient in case of abnormality .We used the microcontroller arduino esp8066, the heart Rate Monitor AD8232 ECG (electrocardiogram) to measure the electrical activity of the heart that can be traced as an ECG, a pulse-eater, a photoresistor LDR and an potentiometer to regulate and modify the current flow in the circuit. We also used add-in PLXDAQ for data acquisition and Jira software for data transfer to the doctor. Our solution is inexpensive and allows people not yet suffering from cardiovascular disease to prevent it.

This paper focus on the development of a new device suitable to detect and measure methane gas in areas of natural gas storage site. This device, the Smart Gas Detection system, can measure the air and water quality, including all the parameters that can have outliers by an eventual gas leak in the aquifer or atmosphere. The air quality parameters measured by low cost sensors, include CH4 and CO2 gas, while for water quality parameters measured include temperature, pH and electrical conductivity. The sensor node is based on arduino UNO microcontroller, receiving the data from the sensors and transmitting to the database on Raspberry pi 3, remotely accessing all the data. It is extremely important to develop devices with the new commercial low-cost sensors to detect and measure gases in atmosphere to monitoring the carbon dioxide and methane due to their role as greenhouse gases and also gas leaks from wellbores can severely affect the health of people and animal.

The authors investigated and characterized different shapes of plastic optical fiber sensors. U-shaped with two different radiuses, coil-shaped and meander-shaped. The sensors were fabricated and measured using a microcontrolled setup. The probes are implemented as refractometry sensors. The small refractive indexes range of 1.33 to 1.39 is used as a reference, produced by different sucrose concentrations. Finally, concentrations of bacterium Escherichia coli in water were detected and the results provided by these sensors are compared.
