Analisis Kinerja Radar Ultrasonik HC-SR04 Berbasis Arduino Uno

Abstract

The research evaluates the performance of radar detection objects based on hc-sr04 using uno arduino modules, servo motors, led, buzzer, and other support components. This radar emits ultrasound waves to the object in front of it and measures the time reflected in the waves to detect distances. Radar performance includes stopping and dilation of a sonar pulse signal when it detects objects, with a maximum range of detection of about 450 cm (450 cm). Although able to pick up materials from about 5 cm to 65> cm, the study noted errors in the measurements of about 1 to 4 cm. Furthermore, results suggest that the longer the range of the flashes, the greater the range of the detection. However, the study suffered a programming failure on processor software 3, especially in visualizing objects of Angle precision and simultaneous use from simulations. The constraint on busy ports is also a boundary factor.
