Hello Guys, im a beginner here and for a control project I need to design a position control for an elevator. It has to be done using analog devices and the first question is: how do I measure position??? I have some ideas, but since I have no previous experience I really really need suggestions.
(by the way, I cant use a potentiometer)
My ideas are:
•Place a magnet at the bottom of the elevator and measure the magnetic field (do you know a cheap sensor????)
•some kind of ultrasonic sensor
•measure light variation in someway, but i think it's kinda hard 2 asure the quantity of light in the model
Id really appreciate your helping hand here, since Im running out of ideas, it doesnt have to be an ellaborated system, in fact, the teacher wants it to be ingenious
thanks a lot
