Connected health is expected to introduce an improvement in providing healthcare and doctor-patient communication while at the same time reducing cost. Connected health would introduce an even more significant gap between healthcare quality for urban areas with physical proximity and better communication to providers and the portion of rural areas with numerous connectivity issues. We identify these challenges using user scenarios and propose LoRa based architecture for addressing these challenges. We focus on the energy management of battery-powered, affordable IoT devices for long-term operation, providing important information about the care receivers’ well-being. Using an external ultra-low-power timer, we extended the battery life in the order of tens of times, compared to relying on low power modes of the microcontroller.

<span lang="EN-IN">In this paper, we proposed to design a next-generation auto theft prevention system by adding significant enhancements and modernizing the existing security features</span><span lang="EN-IN">. </span><span lang="EN-IN">As vehicles turn out to be more refined, vehicle security frameworks must be more grounded than at any other time. A current vehicle uses remote keyless passage framework and Immobilizer framework as the primary weaponry against vehicle robbery. These structures avoid unapproved access of the vehicle to a particular degree, however, are not a secure one. Because of the straightforward and imperfect nature of these security frameworks, auto burglary occurrences worldwide are on the ascent. This venture needs a low power microcontroller however with elite prerequisites. LPC11C14 from NXP Semiconductors addresses these issues and in this manner picked as the primary MCU. It is an ultra-low-power ARM Cortex-M0 based microcontroller that can run up to 50MHz. It has 32KB of Flash memory and 8KB RAM. </span>
