Description
"The main goal of this research is to construct a car parking sensor that detects the motion of a car by using an Arduino Uno microcontroller with an ultrasonic sensor HC- SR04 and to determine the accuracy of HC-SR04. In this sensor, echo technique is used to measure the distances between the car and sensor. The output results are shown on the LCD display in cm scale. The changing distances of the car can be seen in different colors of LED and sound alarm can be heard from the buzzer. The specified color of LED output would display in each 10 cm range respectively. The buzzer made the sound when the object was very near (5 cm) to the sensor. The accuracy of this car parking sensor was determined by comparing software reading and manual reading. The observed error percent was in the range of 0 to 18%. The ultrasonic sensor HC-SR04 can be assumed to have high accuracy."
