Problem:

Falls are a leading cause of injury in elderly patients, especially in hospitals or assisted living facilities. Delayed response to falls can result in severe injuries, prolonged recovery, or fatalities.

Benefits to Healthcare:

– Immediate Response: Alerts caregivers within seconds of a fall.

– Prevents Complications: Reduces risk of bedsores or hypothermia from prolonged immobility.

– Cost Savings: Lowers hospital readmission rates due to fall-related injuries.

– Privacy-Friendly: Uses motion/acceleration data instead of cameras.

Solution:

Deploy MPU-6050 (accelerometer/gyro) to detect sudden orientation changes (e.g., vertical to horizontal) and PIR sensors to confirm immobility post-fall. Use ESP32 to trigger alarms (buzzer, LED) or send SMS alerts (via future GSM expansion).

Process:

1. Fall Detection:

– MPU-6050 tracks sudden acceleration spikes and orientation shifts (e.g., angle > 45°).

2. Immobility Check:

– PIR sensors confirm no movement for a set period after a fall.

3. Alert System:

– ESP32 activates buzzers/LEDs and logs events on OLED screens.

Parts Used:

– ESP32, MPU-6050 (x3), PIR Sensors (x5), OLED Screens (x4), Breadboards (x6).
