Exhaustive Description of the System Architecture and Prototype Implementation of an IoT-Based eHealth Biometric Monitoring System for Elders in Independent Living

In this paper, we present an exhaustive description of an extensible e-Health Internet-connected embedded system, which allows the measurement of three biometric parameters: pulse rate, oxygen saturation and temperature, via several wired and wireless sensors residing to the realm of Noncommunicable Diseases (NCDs) and cognitive assessment through Choice Reaction Time (CRT) analysis. The hardware used is based on ATMEGA AVR + MySignals Hardware printed circuit board (Hardware PCB), but with multiple upgrades (including porting from ATMEGA328P to ATMEGA2560). Multiple software improvements were made (by writing high-level device drivers, text-mode and graphic-mode display driver) for increasing functionality, portability, speed, and latency. A top-level embedded application was developed and benchmarked. A custom wireless AT command firmware was developed, based on ESP8266 firmware to allow AP-mode configuration and single-command JavaScript Object Notation (JSON) data-packet pushing towards the cloud platform. All software is available in a git repository, including the measurement results. The proposed eHealth system provides with specific NCDs and cognitive views fostering the potential to exploit correlations between physiological and cognitive data and to generate predictive analysis in the field of eldercare.

Design and development of software for intelligent monitoring and control system of modern agricultural greenhouse

In recent years, with the improvement of large-scale planting in rural areas, greenhouse cultivation technology has been developed rapidly. Intelligent monitoring and control of modern agricultural greenhouse is a hot topic at present. Based on the design requirements of modern greenhouse and the architecture of software design, this paper designs and develops the main program, data acquisition subroutine, alarm subroutine, control keystroke subroutine and display driver subroutine of the system based on the STM32F103ZET6 main control chip, and realizes the design of intelligent monitoring and control system of greenhouse, This study is of great significance for the establishment of scientific ecological environment of plants and the realization of high quality and high yield of crops.
