IOT based visitor counter

This project is on IOT based visitor counter, we have used ThingSpeak as IOT cloud platform and twitter api to tweet the visitor count data.

This project is all about IOT based visitor counter, initial phase is about getting required output on serial monitor that is Displaying people entered, people left and people in the room, the later phase is about sending the data to ThingSpeak cloud and tweeting when the required condition is met. This project is implemented using NODE MCU, IR Sensor and Thing tweet API. The core logic of this project is that sensors have been placed on entry and exit spots whenever a person makes movement then IR sensor goes low and count will be incremented and sequentially the data is sent to cloud. HTTP post method and react have been used to tweet the required string when 10 people have entered the room”
