Abstract

This banknote denomination and authenticity detection system was designed using an Arduino Uno Atmega 328P microcontroller as the main controller. Two sensors were employed: Sensor A (RGB) to read the color patterns of banknotes for denomination classification, and Sensor B combined with an ultraviolet lamp to verify the presence of security features. The data processing flow is sequential: the denomination is first recognized through RGB analysis, followed by authenticity verification under UV detection. The results are delivered through an audio output, announcing the denomination if the banknote is genuine, or issuing a warning “banknote not detected” if it is counterfeit. The evaluation of the system focused on two main parameters: security and efficiency. Security was measured by the accuracy in distinguishing genuine from counterfeit banknotes, the error rate (false positives and false negatives), and the reliability of the audio output in conveying the correct information. Efficiency was assessed in terms of system response time from banknote input to audio output, the success rate of correct denomination recognition, and the ease of use for visually impaired users.

Abstract

BLDC motor controllers in light electric vehicles such as electric pedicabs are prone to excessive temperature rise due to high current and continuous operation, which may reduce system reliability. This study implements a BLDC motor controller based on the Infineon XMC1302 microcontroller using a Hall-sensor-based block commutation method and an NTC thermistor for thermal protection. Temperature data are acquired through the integrated ADC and used to adaptively regulate the PWM duty cycle via a throttle derating mechanism. Experimental results show that the duty cycle starts to decrease when the temperature exceeds 50 °C and is completely disabled above 70 °C. Laboratory and field tests on an electric pedicab demonstrate a continuous reduction in the speed profile as temperature increases, confirming effective thermal protection performance.
