Now days, we all can see that elevator is used at many places like commercial buildings, shopping malls, hospitals, collages, residential buildings etc. Generally elevator is designed to ferry people or luggage to travel from point A to point B vertically. In this project we made three floor elevator model. We use 89S51 microcontroller as main control unit, which control the operation of the whole circuit. For the movement of elevator we are using 12V D.C. motor which is interface with 89S51. At every floor we put H21A1 (optical interrupter switch) sensor which sense the position of elevator and seven segment display indicate that right now the elevator is at which floor. Here an idea of elevator model working principle is presented, which is microcontroller based application as it is economic, reliable and simple design for its general use.
