1. Pressure Sensor on Railway Tracks Developed by: Pranav (786), Ganesh (784), Aakash (783)

2. Introduction Every year, thousands of animals die after being hit by trains. Animals and obstacles on tracks can cause severe accidents, especially in hilly areas. This project uses pressure sensors to detect animals or boulders on railway tracks and trigger alerts, helping prevent accidents and save lives.

3. Working Understanding The project places 3 piezoelectric wafer sensors along railway tracks. These sensors detect pressure variations caused by animals or obstacles. Piezo wafers are chosen over traditional pressure sensors to avoid false triggers.

4. Landslide Detection (All 3 Sensors) When all three sensors detect pressure simultaneously, the system identifies a landslide. The microcontroller sends GPS coordinates and a 'Landslide' alert to the server using Wi-Fi (ESP8266).

5. Landslide Detection (2 Sensors) If any two sensors (including the middle one) trigger simultaneously, it also indicates a landslide. A 'Landslide' alert with GPS coordinates is sent to the server through the Wi-Fi module.

6. Presence of an Animal on the Tracks When two sensors trigger with a noticeable delay, it indicates the presence of an animal on the track. The system sends a message 'Animal Present' along with GPS data to the server.

7. Animal Passing Over Tracks When all three sensors trigger sequentially with delays, the system interprets it as an animal passing. A message 'Animal Passed' is sent with GPS location details to the XAMPP server.

8. Circuit Explanation The circuit uses three piezo-electric sensors connected to an Arduino microcontroller. An ESP8266 Wi-Fi module sends data to the XAMPP server, and a GPS module provides location data. This integration enables real-time detection and alert transmission.

9. Finished Project The prototype demonstrates accurate detection of animals and landslides using piezo sensors. It can be scaled up for real-world deployment to save animals and prevent railway accidents.
