The world health organization (WHO) has declared the novel coronavirus disease (COVID-19 or 2019-nCoV) outbreak a pandemic, and quarantines are playing a vital role in containing its spread. But globally, the defections of the quarantined subjects are raising serious concerns. If COVID-19 positive, the absconding quarantine subjects can infect more people, which makes their timely detection vital. As the literature suggests, a wearable makes a subject more compliant towards healthcare routines/restrictions; thus, in this work, we have designed an IoT based wearable quarantine band (IoT-Q-Band) to detect the absconding. While designing it, we kept in mind the cost, global supply chain disruption, and COVID-19 quarantine duration, which the WHO recommends. This wearable prototype, with the bundled mobile app, reports and tracks the absconding quarantine subjects in real-time. IoT-Q-Band is an economical solution that could benefit lowincome regions to prevent the spread of COVID-19.

Nucleic acid detection by electrophoresis is still a quick and accessible technique for many diagnosis methods, primarily at research laboratories or at the point of care units. Standard protocols detect DNA/RNA molecules through specific bound chemical dyes using a UVtransilluminator or UV-photo documentation system. However, the acquisition costs and availability of these devices, mainly the ones with photography and internet connection capabilities, can be prohibitive, especially in developing countries public health units. Also, ultraviolet radiation is a common additional risk factor to professionals that use electrophoresis-based nucleic acid detection. With that in mind, this work describes the development of a low-cost DNA/RNA detection smart system capable of obtaining qualitative and semi-quantitative data from gel analysis. The proposed device explores the visible light absorption range of commonly used DNA/RNA dyes using readily available parts, and simple manufacturing processes, such as light-emitting diodes (LEDs) and 3D impression. By applying IoT techniques, our system covers a wide range of color spectrum in order to detect bands from various commercially used dyes, using Bluetooth communication and a smartphone for hardware control, image capturing, and sharing. The project also enables process scalability and has low manufacturing and maintenance costs. The use of LEDs at the visible spectrum can achieve very reproducible images, providing a high potential for rapid and point-of-care diagnostics as well as applications in several fields such as healthcare, agriculture, and aquaculture.

The demand of improving home automation system to control the home appliance in conveniently and efficiently leads to be more concerned about what the user daily activities the way they want to control their home appliances. Since the BLE has the ability to advertise data without the need to be connected to a master (known as BLE beacon). Measuring the best response for best user experience for ESP32 beacon scanner to be used for light control is studied by make the advertisement happen at single and multi-channel and using an ESP32 as scanner with different scanning paraments (ESP32-80 and ESP32-20). The result showed that not only the number of packets on ESP32-80 and ESP32-20 increase, but also it achieve a time response that less than 100ms with 59.47% and 49.93% of received packets for ESP32-80 and ESP32-20 respectively. Advertising on single channel will not only reduce the response time (21% and 14.73% of first packet received on ESP32-80 and ESP32-20 respectively at time that less than 100ms) but also reduce the number of packets received on the ESP32-80 and ESP32-20. It is also shows the ability of using ESP32 as a beacon scanner for home automation system.
