A visual representation of the steps involved in counting process.

The percentage of correctly identified and counted bills.

The time taken by the SwiftCounter to detect and count a bill.

A type of research focusing on developing and improving a device.

A research approach to investigate the effect of different treatments

A study measuring effects after changes or applying different treatments (such as using different sensor setups) to a system.

The SwiftCounter is powered by a 12V Lithium-Ion Battery, which provides power to components like the IR sensors, Huskylens, DC motors, and LCD screen.

The GND pin on the Arduino Nano connects to any ground of the circuit, ensuring a common electrical reference point.

The DC motors are controlled by 5V relays, which are triggered by the Arduino Nano. The relays connect the motors to the Buck Converter's output.

The Buck Converter converts the battery's 12V power down to 5V, suitable for components such as the 5V Relays, DC Motors, and Arduino Nano.

The IR sensors detect the presence of a peso bill, initiating the counting process and guiding it towards the image sensor.

The image sensor identifies the denomination of the peso bill based on its design, for example, identifying a 20 peso bill.

If the image sensor doesn't detect a 20 peso bill, it proceeds to detect other denominations, like 50 pesos, and so on.

The LCD screen displays the types of peso paper bills counted and the total amount, providing visual feedback.

The different values of Peso paper bills used in the SwiftCounter system. The system is designed to identify and count bills of 100, 200, 500, and 1000 PHP.

The SwiftCounter device analyzes Peso bills using image and IR sensors. It counts the bills, identifies their denominations, and displays the total amount and number of each denomination on the LCD.

The SwiftCounter's physical case is designed with specific dimensions and features to hold all components, including an opening for bill insertion, an enclosure for electronics, and an area for the image sensor.

This setup includes an Arduino Nano, two IR sensors, and an image sensor. The IR sensors detect the presence of bills, while the image sensor distinguishes between different denominations.

This setup is similar to Setup 1 but uses four IR sensors instead of two. This allows for improved detection of bills and potentially faster counting.

IR sensors within the SwiftCounter play a key role in determining the presence of bills. They detect the presence of a paper bill as it enters the device.

The image sensor is crucial for identifying the denomination of each Peso bill. It analyzes the image of the bill and determines its value.

The various sensors and components within the SwiftCounter are connected to specific pins on the Arduino Nano, ensuring communication and data transfer.

A device designed to count Peso paper bills using image and IR sensors. It identifies bill denominations and displays the total count and amount.

Setup 1 uses 2 IR sensors and an image sensor, while Setup 2 uses 4 IR sensors and an image sensor. Both aim to count bills.

To test if increasing the number of IR sensors improves the SwiftCounter's accuracy and speed in counting Peso bills.

Arduino Nano, an image sensor, IR sensors, DC motors, relays, LCD, and a DC-DC converter.

Detects the presence of a peso bill, indicating a bill has entered the device and triggering the counting process.

Identifies the denomination of the peso bill by analyzing its image and recognizing its design, for example, identifying a 100 Peso bill.

It checks if the variances of two groups of data (Setup 1 and Setup 2) are equal. It tells us if the spread of data points is similar between the setups.

It tells us if there is a statistically significant difference between the means of two groups (Setup 1 and Setup 2). It helps determine if one setup performs better than the other.
