• Ultrasound is high-pitched sound waves with frequencies higher than the audible limit of human hearing.
• Human ears can hear sound waves that vibrate in the range from about 20 times a second (a deep rumbling noise) to about 20,000 times a second (a high-pitched whistling). However, ultrasound has a frequency of over 20,000 Hz and is therefore inaudible to humans.
• Alright, let’s get straight into the topic and see what are the difference between the two newer and older versions of HC-SR04-P ultrasonic sensors. Well, to be frank, both of them actually provide an approximately similar outcome in terms of distance measuring same goes for the working principle which consists of 1 transmitter and 1 receiver.
