Ultrasonic sensors are widely used in various industries and applications due to their ability to measure distance and detect objects without physical contact. These sensors emit high-frequency sound waves and measure the time it takes for the waves to bounce back after hitting an object. This information is then used to calculate the distance between the sensor and the object. In this article, we will explore some of the most popular ultrasonic sensor models available in the market.
