Background Currently bubble continuous positive airway pressure (bCPAP) is commonly used in low resource settings to treat respiratory distress. However, the accumulation of condensate in the patient's exhalation limb during operation could significantly increase pressure delivered to the body, which can lead to severe respiratory failure in the infant. The objective of this research was to develop a novel low-cost bCPAP device that can monitor and control the pressure delivered to infants. Methods When the neonate expires, the pressure sensor inside the expiratory limb measures the instant positive end-expiratory pressure. The microcontroller decides whether to turn the relay to switch the path of expiration between the two expiratory tubes connected to the valve outlets. This depends on the pressure reading and the cutoff pressure value inserted by the physician. Results The system was tested for accuracy, safety, cost, ease of use, and durability. The prototype was accurate in eight iterations at eight different depths of water that were made to monitor and control the pressure. It was safe and provided suitable pressure for the neonate, and the prototype was built in less than 193 USD. Conclusions The performance testing of the device demonstrated accurate and safe control and monitoring of continuous positive air pressure (CPAP) and oxygen levels with humidity levels safe for infants. The device provides humidified, blended, and pressurized gas for the patient. It allows physicians to easily monitor and control the accumulation of condensate in the exhalation limb of the CPAP machine accurately and safely.

Healthcare has become one of the principal issue with the rise in human population and medical expenditure. For a healthy life, it is essential to follow human body's vital signals. Continuous Monitoring of patient's vital signals cannot be provided outside hospital. As it is hard to monitor the patient's condition for 24 hours, it was proposed in this paper to observe continuously the condition of patient despite the patient being busy with his routine and to screen the health status to the doctors through Internet of Things. This paper proposes health monitoring system using non-intrusive biomedical sensors that measure five parameters like ECG, heartbeat, respiration, temperature and blood pressure. Proposed method makes use of arduino mega Controller to which non-invasive biomedical sensors are connected. The output is displayed on any digital monitoring system using arduino mega. The data obtained from the sensors is uploaded to the ThingSpeak cloud to store and to access patient's information by their doctors or by the concerned for necessary follow-ups in real-time. IoT is a powerful domain where sensors can connect and data is viewed over the Internet.

Steel and iron manufacturing, nonferrous metal production, glass production, ceramic processing, and the creation of various forms of items all rely on material production. High temperatures are used in furnaces for smelting and recycling. An electric furnace may be suitable as natural gas is not widely available everywhere. Bangladesh's melting and recycling machinery is powered by a traditional gas furnace, which is expensive and inefficient. By recycling and reusing scrap metal, natural ore, and alloys, the suggested model has the potential to revolutionize, reducing the build-up of natural energy alloys, gas, and ores. The proposed electric furnace has an enclosed form and uses electricity to generate heat efficiently. To melt reusable metals, electronic materials, and waste materials, an electric furnace system based on the arduino mega as an alternative to the PID controller with Solid State Relay has been developed, which will manage and control the temperature around 1350 degrees C (1623.15 K or 2462 degrees F) by collecting data from the furnace thermostat. This model is made of stainless steel, with a steel frame for the outer shape of the furnace body and control box, a ventilation hole for removing hot gas from inside the furnace, an airtight door for opening the furnace chamber, a digital temperature controller with a furnace B-type thermocouple for measuring and controlling temperature, an ELB for safety, and heat insulation materials with a Nichrome80 heating element in the chamber. The model uses an arduino mega to regulate power and temperature while reducing heat loss via the furnace body, reducing time delays, and increasing efficiency. The findings demonstrate that the desired temperature is reached fast and with less electricity than the other electric furnaces, indicating that the model is energy efficient. The smelting temperature for aluminum, copper and other similar materials has been effectively covered. This model has better efficiency si

Now days the rapidly increasing vehicles & large time delays between traffic lights leads to wastage of fuel & time. To overcome this problem, we go through smart traffic control system using green energy. The conventional traffic lights are works on fixed time period allotted to each side of junction which cannot be varied & junction timing allotted are fixed In the smart traffic control system the traffic is controlled according to traffic density within the particular distance. This system is done using arduino mega interfaced with IR sensors & timing at the junction changes automatically. This system comes under digital India campaign and supports Smart City Concept.
