Train accidents are a major concern all over the world, and their prevention is of utmost
importance. In this project, we will be utilizing an Arduino Uno to create a train accident
prevention system. The system will use ultrasonic sensors to detect the presence of a train on
the railway track and then alert people and animals in the area by activating alarms and lights.
Additionally, we will also use heat sensors to monitor the temperature inside the train, and
control it by using water to prevent train burning accidents.

Ultrasonic sensors emit high-frequency sound waves that bounce off objects and return to the
sensor, allowing it to determine the distance to the object. By placing the sensors strategically
along the railway track, the system can detect the presence of a train and take action
accordingly.
Once a train is detected, the system activates alarms and lights to alert people and animals in
the area. The alarms can be loud sirens or buzzers, while the lights can be flashing LED lights
or spotlights. These alerts help to prevent accidents by warning people to stay clear of the
tracks.

Heat sensors can detect sudden temperature increases, which can indicate a fire or
overheating. By monitoring the temperature inside the train, the system can take action to
prevent train burning accidents. This is done by controlling the temperature using water. Water
can be sprayed on the train to cool it down or extinguish a fire if detected.

Overall, the train accident prevention system is an important tool for ensuring the safety of
trains and people who use the railway system. By detecting potential hazards and taking
appropriate actions, the system can help prevent accidents and save lives.
