What is a bidirectional visitor counter?
This project can be used to count and display the number of visitors entering inside any conference room or seminar hall. This is a bidirectional counter which means it works in a two way. That means counter will be incremented if person enters the room and will be decremented if a person leaves the room.
How to make Visitor counter using Arduino?
To count the number of people entering any facility the easier way is to create a machine that automatically counts the people coming in. This can be achieved by using a sensor that detects any interference in its path and that is the infrared sensor.
How do you make an object counter with infrared sensor Arduino?
counter using ir sensor Circuit Diagram Connect the 5-volts pin of the Arduino with the VCC pin of the IR sensor and also with the LCD display module. Attach the GND pin of the Arduino to the GND pin of the IR sensor and also with the LCD display module. You can use a breadboard for making the common connections.
Which sensor is used to count people?
Thermal Counters Thermal sensors are installed top-down at the entrances to detect human body temperatures and count them. Typically, thermal imaging people counters are negatively affected by sunlight since sunlight radiates the whole light spectrum.
Which sensor can be used for counting?

What is a 3 bit counter?
The 3-bit Asynchronous binary up counter contains three T flip-flops and the T-input of all the flip-flops are connected to ‘1’. All these flip-flops are negative edge triggered but the outputs change asynchronously. The clock signal is directly applied to the first T flip-flop.
What is a counter sensor?
A Counter is a device that counts the number of objects or the number of operations. It is called a Counter because it counts the number of ON/OFF signals input from an input device, such as a switch or sensor.
What is parallel counter?
A parallel counter is a combinational logic circuit that receives a set of binary count signals in parallel and determines the final count after some fixed delay. In this paper, a more general parallel counter is presented whose count inputs have three states (i.e, down, none, and up or, equivalently, -1, 0, and 1).
