This is my plan to make the door work automatically. I hade made the flow chart by using logicator 2004.
The picture in the left side is the picture using logicator.
It even has the program to open the door when the fire alarm rings and when the fire alarm rings It keeps on checking if there is people inside and if there is the people inside the door keeps on opening for 500 seconds and if the people all gets out it is going to close.
The other program is when there is people coming the motion sensor will work and then the door will open for 4 seconds and then it is going to close.

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

I answered the questions how the automatic door works, how it is activated.

What do I need to know before I can start this project and how can I find out about them?

I think I need to know about the pulley and I can find it in the internet(Wikipedia or Encyclopedia)
