During my studies for a Software Engineering Degree at Solent University, UK, I undertook a project that exemplified the convergence of cutting-edge technology and practical healthcare solutions. Through diligent research and development, I created a Health Care IoT Monitoring System.
The Health Care IoT Monitoring System is designed to monitor various aspects of a patient's physical health, including body temperature, heartbeat level, and blood glucose level. Utilizing advanced sensors such as the DHT11 for temperature, Pulse Sensor for heartbeat, and Glucose Sensor for blood glucose, this system provides real-time data that can be directly accessed through an IoT cloud platform. These components are seamlessly integrated into a Printed Circuit Board (PCB), ensuring reliability and efficiency in data collection. With this device, healthcare professionals can remotely monitor crucial health indicators, enabling timely interventions and personalized treatment plans. The primary objective of this system is to mitigate the risk of patient mortality in hospitals by facilitating early detection of health anomalies. Additionally, it aims to enhance the overall physical well-being of patients and contribute to advancements in the medical field. By leveraging the power of IoT technology, this innovative solution not only addresses immediate healthcare needs but also fosters continuous improvement and innovation in patient care.
This system consists of two devices: the main device, which is fitted to the patient and connected to sensors including the DHT11, Pulse Sensor, and blood glucose sensor, and the receiver device, which solely receives messages from the chief doctor via the cloud platform through the main device. The receiver device is typically located in the hands of staff members or in the staff room, facilitating quick access to patient data for assistant doctors. The implementation of the smart Health Care IoT Monitoring System necessitates the creation of a dedicated smart unit ward room within a hospital, equipped with all necessary facilities. Upon a patient's admission to this unit, the three sensors are affixed to the patient's body to monitor their heart rate, blood sugar level, and body temperature. These vital signs are then directly monitored by the chief doctor assigned to the hospital's smart unit through IoT cloud platforms. In the event of a deterioration in the patient's health condition, the chief doctor can initiate action by signaling through the cloud platform. This signal triggers a response in the main device, prompting it to relay information about the patient's health status to the receiver device. Subsequently, the assistant doctor is promptly alerted and can proceed to administer necessary treatments directly to the patient.
This diagram consists of two main components: the main device and the receiver device. The main device is responsible for transmitting data to the IoT cloud platforms using the MQTT protocol over the internet. In the event of an emergency, when the emergency button is pressed within the platform, the signal is routed back to the main device. Subsequently, the main device relays this information to the receiver device using radio signals facilitated by the NRF24L01 transceiver.
The IoT device was meticulously developed using a circuit board. To ensure precision and efficiency in design, I utilized the EasyEDA software for PCB layout and schematic design. Following the design phase, I undertook the circuit assembly process manually, carefully integrating each component to guarantee optimal functionality and reliability. The development of the IoT device involved a comprehensive approach, from conceptualization to implementation. By leveraging cutting-edge tools and hands-on assembly techniques, I ensured that the device met stringent quality standards and performance criteria. This meticulous attention to detail in both design and assembly underscores my commitment to excellence in engineering practices.
