INTRODUCTION

Health is a chronic respiratory condition that affects millions of people worldwide. It is characterized by airway inflammation and hyper-responsiveness, resulting in recurrent episodes of wheezing, breathlessness, chest tightness, and coughing. Environmental factors such as air pollution, allergens, dust, and changing weather conditions can significantly worsen symptoms, making real-time monitoring and prediction of health safety levels essential. In this context, internet of things projects play a crucial role in enabling continuous health monitoring and early risk detection.

This project introduces a comprehensive healthcare monitoring system developed as part of innovative internet of things projects, integrating wearable technology, sensor networks, machine learning algorithms, and mobile applications. The primary objective is to provide individuals and healthcare professionals with timely insights into both environmental and physiological factors that contribute to health exacerbations.

This user-centric design ensures accessibility and practical usability, which are key goals of successful internet of things projects.

In conclusion, this integrated system demonstrates how internet of things projects, combined with machine learning and mobile technologies, can deliver a powerful solution for real-time health monitoring and prediction. By offering valuable insights into health triggers and enabling proactive health management, the proposed system aims to improve safety, awareness, and overall quality of life for individuals living with chronic respiratory conditions.

PROBLEM STATEMENT

Despite continuous advancements in medical treatments, health remains a major global public health concern, affecting millions of individuals and creating significant challenges in long-term management. One of the critical limitations faced by individuals with health and healthcare professionals is the absence of reliable real-time monitoring and prediction tools. This gap highlights the need for intelligent internet of things projects that can support proactive health management.

Conventional health management approaches largely depend on subjective symptom reporting and periodic clinical visits. Such methods fail to capture the dynamic and fluctuating nature of health triggers, including sudden physiological changes and environmental conditions. As a result, timely intervention becomes difficult, increasing the risk of unexpected health exacerbations. This limitation reduces the effectiveness of traditional monitoring systems when compared to modern internet of things projects that enable continuous data collection.

Additionally, existing monitoring techniques do not provide real-time insights into environmental factors such as air pollution, dust, smoke, allergens, temperature, and humidity, all of which significantly influence health conditions. The lack of personalized health safety level prediction based on individual physiological and environmental data further complicates effective disease management. These challenges demonstrate the growing necessity for healthcare-oriented internet of things projects integrated with intelligent analytics.

Therefore, there is a critical need to design and implement a comprehensive system that combines wearable technology, sensor networks, machine learning algorithms, and mobile applications. Such internet of things projects can enable real-time monitoring and accurate prediction of health safety levels. By providing timely insights into both environmental and physiological factors, the system can empower individuals with health and healthcare professionals to adopt proactive management strategies, ultimately improving disease control and quality of life.

EXISTING SYSTEM

The existing system for managing health primarily depends on conventional medical practices such as manual symptom monitoring, periodic clinical consultations, and medication adherence. While these approaches have been widely used, they lack the real-time monitoring and predictive capabilities offered by modern internet of things projects, making them less effective in addressing sudden health exacerbations.

Key Components of the Existing System:

1. 1. Symptom Monitoring:
      Individuals with health are required to self-monitor symptoms such as wheezing, breathlessness, and coughing, and manually record changes in their condition. This information is typically communicated to healthcare professionals during scheduled visits. Such manual reporting is subjective and may not accurately reflect real-time health conditions, unlike automated internet of things projects.

1. 1. Peak Flow Meters:
      Peak flow meters are commonly used to measure peak expiratory flow rate (PEFR) to assess lung function. Although useful, these devices require active patient involvement and do not provide continuous or real-time data monitoring, limiting their effectiveness when compared to sensor-based internet of things projects.

1. 1. Inhalers and Medication Adherence:
      Medications such as bronchodilators and corticosteroids are prescribed to control symptoms and prevent exacerbations. However, inconsistent medication adherence and lack of real-time feedback often result in suboptimal health control, an issue that intelligent internet of things projects aim to address.

1. 1. Environmental Trigger Awareness:
      Patients are advised to avoid known triggers like allergens, smoke, air pollution, and weather changes. However, real-time monitoring of environmental parameters is rarely available in traditional systems, reducing the ability to anticipate and prevent health attacks without the support of internet of things projects.

1. 1. Clinic Visits and Consultations:
      Health assessments and treatment adjustments are performed during periodic clinic visits based on patient feedback and diagnostic tests. These visits may not be frequent enough to detect rapid changes in health conditions, resulting in delayed interventions.

Overall, the existing health management system relies heavily on patient self-reporting, infrequent clinical evaluations, and reactive treatment strategies. This approach lacks real-time insights, predictive analysis, and personalization, highlighting the need for advanced internet of things projects that enable continuous monitoring and proactive health management.
