Vibration sensor to avoid train accident
The viberation sensor is attached in the train path.In the receiever side,I connect one alarm.In the transmitter side the viberation sensor sense the viberations and it converts into electrical signal.
The electrical signal is transferred using the bluetooth. The receiver recieves that signal and it produce some sound when the train crosses the vibration sensor. The distance between the transmitter & reciever is 100m.
I use one transmitter(master) and many recievers. Using this viberation sensor,we reduce the accidents. I want to give some alertness to the railway workers and people.
