Elderly Fall Detection System

Tech Used:

1. STM32 Microcontrollers
2. Adafruit 9-DOF Accel/Mag/Gyro+Temp Breakout Board - LSM9DS1
3. UART Communication
4. KiCad (For Electrical Schematics)
5. C

Description:

This project is an elderly fall detection system that makes use of two STM32 Microcontrollers. One STM32 is worn by the user and constantly monitors sensor data, to detect a fall. Upon successful detection of a fall, the STM32 sends a signal via UART communication to the receiving STM32, which is usually with the caregiver. The receiving STM32 sends a PWM signal to activate a Piezo buzzer and alert the caregiver.
