There are safety threats due to unexpected uncontrolled sudden opens and shuts of entrance doors. This work aims to develop a computer-simulated wind velocity model to study the doors' risky behavior by analyzing the relationship between wind velocity and the corresponding door movements. We develop a microcontroller-based system to detect when a door is opened, and record the wind velocity and door open distance when the door is opened and closed. This process is completed using an anemometer to measure the wind velocity, a magnetic door switch to detect when the door opens, using an ultrasonic sensor to measure the door distance, and calculating the time the door was open using the Arduino timer. The experiments are conducted inside a room., where wind speed and maximum door open distance can be controlled. The preliminary results show that the door open speed and distance increases significantly with increased wind speed. The proposed model can be extended as a potential remedy to dangerous threats for buildings and building occupants.
