What role do sensors play in modern elevator systems?

Sensors play a crucial role in modern elevator systems by providing critical information that enhances the overall safety and functionality of the system. They are responsible for detecting passenger presence, sensing obstructions in the door, and determining the car's position within the hoistway.

When passengers approach the elevator, sensors can identify their presence to ensure that the doors do not close unexpectedly, thereby preventing accidents. Additionally, sensors monitor for any obstructions in the door's path, which is vital for safety to avoid trapping individuals or objects. By tracking the elevator car's position, sensors help accurately align the car with the landing floor, allowing for smooth and safe boarding and alighting.

Together, these detection capabilities contribute significantly to the operational efficiency and safety features of modern elevators, making it essential to have reliable sensor systems integrated within the elevator design.
