My project In Fab Academy

Smart Seat Belt:

Smart seat belt can detect accidents and react to the accidents.
If there is a vibration the vib sensor will detect it and pull the
seat belt.After the vibration is over a count down will start.In the
middle of the count down if vib comes the solenoid will not release.
But if there is no vib in the middle of the count down the solenoid
will release.If there is fire and water the solenoid will immediately release.
