Smart Fall Detection for Elderly Person using NodeMCU

Introduction

The Smart Fall Detection System using NodeMCU is an advanced IoT-based solution designed to detect falls in elderly individuals and send instant alerts to caregivers or emergency responders. This system enhances personal safety and ensures timely assistance in case of accidents.

Components Used

• NodeMCU (ESP8266) – For wireless connectivity and data processing
• Accelerometer and Gyroscope Sensor (MPU6050) – To detect sudden falls based on movement patterns
• Buzzer – To alert nearby people when a fall is detected
• GSM Module (optional) – To send SMS alerts to emergency contacts
• IoT Cloud Platform (like Blynk or Firebase) – To monitor fall events remotely

Working Principle

The MPU6050 sensor continuously monitors the movement and orientation of the elderly person. When an unexpected fall or imbalance is detected, the system processes the data using NodeMCU and triggers an alert. The alert is sent via:

• Buzzer sound for immediate local assistance
• WiFi-based notification to a mobile application
• SMS alert (if a GSM module is included)

Key Features

✔️ Real-time Fall Detection – Immediate detection and notification of falls
✔️ Wireless Communication – Alerts can be sent via WiFi or SMS
✔️ IoT Connectivity – Enables remote monitoring for caregivers
✔️ Compact and Wearable – Can be integrated into a wearable device
✔️ Low Power Consumption – Ensures long battery life for continuous operation

Applications

✅ Elderly Care Homes – Ensures quick assistance for senior citizens
✅ Hospitals & Clinics – Enhances patient safety
✅ Home Use – Ideal for individuals living alone or with limited mobility

This Smart Fall Detection System improves safety, reduces emergency response time, and offers peace of mind for both elderly individuals and their families.
