Introduction of HC-SR04HC-SR04 is a very popular sensor for measuring distance. It emits ultrasonic waves at a frequency of 40KHz. The ultrasonic waves travel through the air. If there are objects or obstacles in the path, it will bounce back to the module. Taking into account the propagation time a
Ultrasonic sensors are devices that convert ultrasonic signals into other energy signals (usually electrical signals) to measure distance from the sensor to the target object. Ultrasonic wave is a mechanical wave with a vibration frequency higher than 20KHz and it has the characteristics of high fre
Ultrasonic sensors are sensors developed using the characteristics of ultrasound. Ultrasonic ranging sensors are sensors that convert ultrasonic signals into other energy signals (usually electrical signals). Ultrasound is a mechanical wave with a vibration frequency higher than 20kHz. It has the ch
