Development of Prototype Automatic Sensor Roll-Up/Down with Alarm System

In commercial and industrial settings, roll-up doors are crucial for efficient access control and security. This developmental study developed a prototype automatic sensor roll-up/ down door with alarm system in terms of technical features; operating performance; sensitivity; audibility; and level of acceptability in terms of composition, operating performance, and safety. The device demonstrated several technical features that improve user control and security. Its components included an electric motor with 2.2 kVA rating, a single-phase motor with a voltage of 220 volts, speed of 2800 RPM, capacitor value of 15 µF, current of 13.3 A, and frequency of 50 Hz. The automatic transfer switch had dual power supply. The reducer gear motor had reduction ratio of 50:1. The control circuit used Arduino Uno R3 board with indicator lights, switches, and magnetic contactor. The alarm system was equipped with three alarms: for motor control issues, forced entry detection, and password requirement for opening and closing. Motion sensor and limit switch made up the automated sensor. After 10 trials, the door's operational performance was found to consistently open and close in 15 seconds. The Arduino Uno program successfully sent commands to the device, indicating operational efficiency. Door mechanism's responsiveness and dependable operation were indicated by regular timing. The device was sensitive at 2, 4, and 6 meters, and with a score of 10 in 10 trials. The door operated dependably and reacted to motion efficiently at all tested distances. It generated sound audible at all tested distances. In terms of composition, operating performance, and safety, it was very acceptable in each factor of evaluation.
