Scientific and technological developments are bringing in innovations which seemed impossible even a few years back. We have seen upgrades in products, making them better and more user-friendly. One solid example in this context is an ultrasonic detector. These sensors were always there in the market, but there has been a huge increase in their demands recently. There are various factors attributing to the rising demand for ultrasonic sensors, such as their flexibilities, capabilities, and, most importantly, low cost. You can see extensive use of ultrasonic sensor cylindrical in drones, autonomous vehicles, and robots.
In this article, we will discuss in detail ultrasonic sensors, their uses, their strengths, weakness, etc. Continue reading the article to know more.
What is an ultrasonic sensor?
An ultrasonic sensor is defined as an electronic device that emits ultrasonic sound waves to measure the distance of a target object. This is followed by an immediate conversion of the reflected sound into an electrical signal. Bats use this same concept of echolocation to find their prey.
The frequency of ultrasonic sensors is generally between 23 kHz and 40 kHz. The audible range of human hearing is 20 kHz. Thus, the frequency of the sensors is quite high, hence the name ultrasonic.
At room temperature, the speed of sound in air is 343 meters per second. You can easily convert this time to distance. You have to remember that the ultrasonic frequency travels both ways from the object which is being sensed. Hence the formula goes:
Distance (in meters) = (time elapsed [in seconds] x 343 [meters/second]) / 2
You can change the units in this equation as you need. However, from this equation, it is clear that the sensor works in a straightforward manner.
