Fall Detection Project with Code and Circuit

The Fall Detection Project is an interactive monitoring system built around a microcontroller development board designed to detect sudden physical drops or impacts. At the heart of the system is an integrated accelerometer sensor, which continuously measures spatial acceleration and movement along multiple axes. The microcontroller runs software written in the Arduino IDE, utilizing specific sensor libraries to read real-time coordinate data from the accelerometer. When the user moves normally, the sensor readings stay within safe baseline limits. However, if a sudden acceleration change characteristic of a fall is registered by the sensor, the microcontroller processes this event and triggers two primary output responses: it sends an alert message through serial communication to a connected computer or display, and it drives two 5mm LEDs. The LEDs are protected by 1Kohm resistors to limit current flow from the digital output pins, ensuring they illuminate safely without drawing excessive current. The entire circuit is wired using jumper wires and powered via the InduBoard 3cm sized dev board. By continuously polling the sensor data and combining visual indicators with serial output, the system acts as an automated safety monitor capable of signaling caregivers immediately when an abnormal movement event occurs.
