(1)The automatic opening and closing of the door is cheap and the elevator is cheap.
(2)It is installed in front of it, so it frequently repeats unnecessary opening and closing operations. In addition, the electromagnet of the opening and closing device is ONOFFed at the maximum output, making the sound of the latch hitting very loud. This phenomenon is more painful than the noise of the washing machine because it repeats at bedtime, so we need to take action quickly.
(3)For example, you can change the electromagnet’s strength for a long enough time to reduce the impact on the latch and buffer it to reduce the impact. In addition, in order to prevent repeated movement of the sensor, use the one that comes out of the PIR sensor to prevent frequent opening and closing operations, and exclude the sensor’s installation position detection range in front of the elevator.

The automatic opening and closing of the door is cheap and installed in front of the elevator, so it frequently repeats unnecessary opening and closing movements.
In addition, the electromagnet of the switchgear is ONOFFed at full power, making the clasping sound very loud.
This phenomenon repeats during bedtime, which is more painful than the noise of the washing machine, so please take action quickly.
For example, you can change the electromagnet’s intensity for a long enough time to reduce the impact on the latch and buffer it to reduce the impact.
In addition, to prevent repeated movement of the sensor, use a better one than the PIR sensor to prevent frequent opening and closing operations, and exclude the sensor’s installation position detection range in front of the elevator.
That’s KAIST.

(2)If you leave it to the installation company to improve it, it will cost a lot of money and take a long time, and you don’t know the results of the improvement, so it would be better to ask that student to pay for the repair and improve the device.
