The project aims to develop a wearable device that continuously monitors health parameters and detects falls to enhance the safety of users, especially the elderly or those with medical conditions. The system integrates various sensors and communication modules to collect data, process it, and transmit it to caregivers or medical personnel in case of emergencies.
Components and Their Functions:
1.Arduino UNO R4 WiFi: Acts as the main development board and central processing unit for the system. Collects data from the connected sensors, processes the data, and manages communication with external devices via WiFi.
2.MPU6050 (Accelerometer and Gyroscope): Detects motion and orientation, monitors the user's movements and detects falls by analyzing sudden changes in acceleration and orientation.
3.MAX30102 Heart Rate and Pulse Oximeter Sensor Module: Measures heart rate and blood oxygen levels, provides real-time monitoring of the user's cardiovascular health, detecting abnormalities such as irregular heartbeats or low oxygen saturation.
4.NEO-6M GPS Module with EPROM: Provides geographical location data, tracks the user's location, which is essential for sending accurate emergency alerts and locating the user in case of a fall or health emergency.
5.SIM800L GPRS GSM Module: Enables cellular communication, sends emergency alerts via SMS or calls to predefined contacts, providing location and health status information when WiFi is unavailable.
6.Black Electronic Building Blocks Big Key Button Module (Panic Button):High-level output button for manual alerts, allows the user to manually trigger an emergency alert in case of immediate danger or health issues that the automated system might not detect.
-->System Workflow
1.Data Collection: The sensors (MPU6050, MAX30102, NEO-6M) continuously collect data related to the user's movements, heart rate, oxygen levels, and location.
2.Data Processing: The Arduino UNO R4 WiFi processes the sensor data. It uses algorithms to detect falls from MPU6050 data and monitor heart rate and oxygen levels from MAX30102.
3.Emergency Detection: If a fall is detected or abnormal heart rate/oxygen levels are recorded, the system prepares to send an alert.
4.Communication:
Via WiFi: If WiFi is available, the Arduino UNO R4 WiFi sends the data to a central server or a mobile app for real-time monitoring by caregivers.
Via GSM: If WiFi is not available, the SIM800L module sends an SMS or makes a call to predefined emergency contacts, including the user's location from the GPS module and health status.
5.Manual Alert: The user can press the panic button to manually trigger an emergency alert, ensuring quick response in case the user feels unwell or unsafe.
-->Applications:
1.Elderly Care:
Benefits: Continuous health monitoring and fall detection can significantly enhance the safety of elderly individuals living alone or in assisted living facilities.
Use Case: An elderly person wearing the device can have their heart rate, oxygen levels, and movement monitored. In case of a fall or abnormal health readings, caregivers or family members are immediately alerted, allowing for quick response.
2.Medical Patients:
Benefits: Provides real-time health monitoring for patients with chronic conditions such as heart disease, COPD, or diabetes.
Use Case: Patients discharged from the hospital but still requiring monitoring can wear the device to keep track of vital signs. Doctors can receive updates and alerts about any critical changes, ensuring timely medical intervention.
3.Military Soldiers:
Benefits: Ensures the safety and health of soldiers in the field by monitoring their vitals and detecting falls or injuries.
Use Case: Soldiers in remote or combat areas can use the device to report their health status back to medical units. In case of injury or fall, an automatic alert can be sent with the soldier’s location, facilitating rapid medical support.
4.Mining Workers:
Benefits: Enhances the safety of miners working in hazardous environments by monitoring their health and detecting accidents.
Use Case: Miners can wear the device to monitor their heart rate, oxygen levels, and movements. In case of a fall or if the environment becomes unsafe, an alert is sent to the mining control center, ensuring timely rescue operations.
5.Athletes:
Benefits: Helps in monitoring the health and performance of athletes during training and competitions.
Use Case: Athletes can use the device to track their heart rate, oxygen levels, and movement patterns. Coaches and medical staff can receive real-time data to optimize training and prevent injuries.
6.Construction Workers:
Benefits: Provides safety and health monitoring for workers in high-risk construction sites.
Use Case: Construction workers can wear the device to monitor their vitals and detect falls. In case of an accident, immediate alerts can be sent to the site supervisors, ensuring quick medical attention.
7.Remote Workers:
Benefits: Ensures the health and safety of workers in isolated or extreme environments.
Use Case: Researchers or workers in remote locations can use the device to monitor their health and ensure they are safe. In case of health issues or falls, emergency services can be alerted with precise location details.
8.Disabled Individuals:
Benefits: Enhances the independence and safety of individuals with disabilities by providing continuous health monitoring and emergency alerts.
Use Case: Individuals with mobility issues can wear the device to ensure their health is continuously monitored. Caregivers can be alerted in case of falls or health emergencies, providing peace of mind and quick response.
-->Conclusion
This wearable device enhances user safety by providing continuous health monitoring and immediate fall detection. The integration of various sensors and communication modules ensures comprehensive health data collection and reliable emergency communication, making it a valuable tool for vulnerable populations.
