chaewonk2017 Sliding Door Project

I have made 4 designs of Sliding door.
Design ....

• Design 1 is a door which is automatic and the sensor is really sensitive.


• Design 2 is a door which needs an pressure sensor.


• Design 3 needs a remote sensor and a person to press it all the time when people comes.


• Design 4 is a motion sensor which uses low-power microwave radar.

and.... I have chosen Design 4 because it doesn't need lots of money and doesn't use lots of electicity.

for the output I need....

• Door motor to make the door open and close. (When the people comes in)

For the input I need....

• motion sensor(to know if the people are coming or not
