Advanced Elevator with Load Monitoring and Alerting

Download Project Document/Synopsis

In Earlier days the size of buildings was small and the elevators were rarely seen. But nowadays with the rise in construction of skyscrapers, there is a greater need of Elevators. As the numbers of floors increases, the elevator needs to be capable of handling the weight and lift the load to the greater height. This system is powered by Atmega 328 microcontroller, it consists of an LCD display,3 IR sensors, two 7 segment displays, ADC and a door. After powering it on, till no passengers being arrived in the elevator, the door of elevator remains close. As the passengers arrived the door opens and allows the passengers to enter into the elevator. This system uses the average weight algorithm, it assigns a fixed weight of each entering passenger. Based on the weight of the passengers inside the elevator, total weight is calculated. The elevator stops at each floor and allows the passengers to enter and exit. When more passengers enter and the elevator gets over weighted, it raises an alarm.
An elevator is rated with the maximum number of weights and if the load exceeds then the maximum rated weight, it alerts of overload by raising the alarm. When the extra passengers exit, the door gets close and the further procedure starts.
