hello guys,
what is the best sensor to monitor a movement? for example if something moves then a buzzer sounds if it stops then silent.
i was thinking a tilt sensor like SW-520D but under specific situations then it doesnt work.
is an accelerometer sensor good for this work?
i want to drive it with a pic16f88 is that possible?
also the first idea was with a ball bearing sensor but for example if the pord is upside down then the ball bearing will not work. i want to make something that when it is not moving nothing happens and if it moves whatever position then the buzzer will make noise
