Your Footstep Detection and Alert System is a smart monitoring system designed to detect footsteps and provide an alert when movement is detected. The system uses four piezoelectric sensors to detect vibrations caused by footsteps, while an Arduino Uno processes the sensor signals and identifies a true peak value above the set threshold. When a footstep is detected, the buzzer produces an audible alert, and the Arduino sends a trigger signal to the ESP32-CAM, which captures an image and sends it to Telegram for remote monitoring. The system also uses a 16×2 I2C LCD to display the system status and sensor readings. Overall, the project combines sensor technology, microcontroller processing, camera monitoring, and IoT communication to create a low-cost smart alert system related to SDG 9: Industry, Innovation and Infrastructure.
