When taking the elevator, we often encounter the situation that the door opens without anyone outside. The Elevator Decider is designed to judge if there is anyone outside by inducing the infrared rays from human body before the elevator arrives at the target floor. The elevator will stop if there is someone outside, on the contrary, it will keep moving. Thus, the waiting time and electrical energy is easily saved.
