Smart Digital Bi-Directional Visitors Counter Based on IoT

Abstract

This research presents the design of a smart digital bidirectional visitor counter (SDBVC). The million religious visits especially in Iraq increased the need for accurate smart counting systems for human to count the largest gathering of people in one place. The major focus is on counting huge number of humans enter one place from multiple entrance gates. The central processing unit (CPU) receives all the data from these gates and finally makes the studies about the overall human number, men number, women number, the period of the day that this number reach the highest and smallest number and etc. The proposed project hardware contains multiple Wi-Fi based Arduino microcontrollers (like Node-MCU Arduino): one Arduino in each gate which is called transmitter and one in CPU which is called receiver, multi ultrasonic sensors for each transmitter placed on the entrance gates (men gates data separated from women gates data). ThingSpeak.com is used to save the large recorded data for long time for example many days and give results and records about the number as Arba’een Pilgrimage for Imam Hussein shrine in Iraq. The proposed system gives accurate results on the number of entered and exit people to and from one place.
