Description
The IoT-Based Fall Detection System works by continuously monitoring the movement and orientation of a person using the MPU6050 accelerometer and gyroscope connected to the ESP32. When a sudden change in acceleration, body orientation, and inactivity is detected, the ESP32 identifies it as a possible fall. The buzzer is activated to alert the person, while a short time is provided to cancel the alert if it was a false detection. If the fall is confirmed, the GPS module obtains the person's location, and the ESP32 sends the emergency information to an IoT platform through Wi-Fi. If GSM is included, the SIM800L module can send an SMS or make an emergency call to a registered contact along with the location. The OLED display and LED indicators show the current system status, while the emergency button allows the user to manually send an SOS alert.
