Abstract
This paper presents the design and implementation of a proximity-based collision detection system using an HC-SR04 ultrasonic sensor and an Arduino Uno R3 microcontroller. The system provides audible feedback through a passive buzzer whose beeping frequency is dynamically adjusted according to measured distance. Three distinct operational zones are defined: continuous slow beeping for distances above 15 cm, progressively increasing beep rate in the 5–15 cm range using the Arduino map() function, and a constant tone for distances below 5 cm. The ultrasonic ranging function is implemented manually without any external library. Experimental results confirm consistent distance readings within ±1 cm over the rated 2–400 cm range, and audible zone transitions proved intuitive during user testing. The design is compact, low-cost, and directly extensible to multi-sensor or visual-feedback configurations.
Addressing the industrial automation sector’s requirement for high-precision non-contact distance detection, this paper presents an ultrasonic ranging embedded system based on an STM32 microcontroller. The system hardware utilizes an STM32F103 series microcontroller as its core. This microcontroller controls the transm...

Reversing radar can monitor and warn the obstacles behind the vehicle in real time, and effectively reduce the incidence of reversing accidents. It is a key vehicle safety auxiliary system to make up for the defects of traditional reversing methods and improve parking safety. In this paper, an intelligent ultrasonic re...

Infrared distance sensors are widely used in robotics and automation due to their low cost and small size. However, their output voltage versus distance characteristic is highly nonlinear and sensitive to target reflectivity. This paper presents a systematic performance analysis of the GP2Y0A21 sensor within its effect...

The growing number of vehicles has made parking increasingly challenging, particularly in areas with limited parking space. Conventional parking methods often rely on drivers' visual judgment, which may lead to inaccurate distance estimation and increase the risk of minor collisions. To address this issue, this study p...
