In this project, we will make IoT IR Based Bidirectional Visitor Counter using NodeMCU ESPP8266 & Ubidots MQTT. You can use this project for monitoring the total number of incoming, outgoing, and current visitors online from any part of the world using Ubidots Dashboard. To count the incoming and outcoming visitors, it is better to use an Infrared or IR Sensor. The Visitors data uploads automatically to Ubidots cloud using the NodeMCU ESP8266 WiFi Module.

You can use this NodeMCU Bidirectional Visitor counter in the hall, Shopping mall, office, functions in the entrance gate to count the total number of visitors. The device counts the total number of people entering through the gate & also counts the total number of people leaving through the different gates. And finally, it calculates the total number of current people by subtracting the outgoing visitor from the incoming visitor. When even a single person is found inside the room, the light turns on automatically. When no people are present in the room, the light turns off automatically.

In one of my previous projects, I made the Visitor Counter Project using Arduino. But this time we will send the data to the cloud instead of watching it on OLED Screen. We can make this IoT Visitor Counter using ESP8266 Wifi Module, a pair of IR Sensor, OLED Display, and a Relay Module. Apart from these main components we also need some passive electronic components & PCB Board. The project is simply easy and even a beginner can make it without any difficulty.
