Design and Fabrication of an Intelligent Self Closing and Opening Door

Authors

This project demonstrates an intelligent self-opening and closing door

system that is dependent on human motion close to the door. The door

achieves this functionality with the help of a PIR sensor. Every live

body emits some infrared energy, this energy is sensed by the PIR

sensor from a good distance and uses this signal to process the opening

and closing of the door. The use of an automatic door can be made to

solve most of the challenges associated with manually operated doors.

These challenges necessitate the design and fabrication of a door

system that is capable of opening and closing on its own. The door was

designed and built with locally sourced materials. The self-opening and

closing sliding door was tested after fabrication and the system was

validated to have performed as expected. The design values for the

design parameters were compared to the actual values measured from

the system while it was running. The percentage deviation of actual

values from design values for design parameters such as door opening

time, door delay time, door maximum velocity, door minimum velocity,

and total time taken for the door to complete one operating cycle are

7.69%, 3.15%, 3.53%, 14.89%, and 6.51%, respectively. The

comparison revealed that the discrepancies between the actual and

design values were insignificant. Thus, the design and fabrication of an

intelligent door system was successfully executed.
