Ultrasonic sensors are among the most widely used technologies today. From object detection to complex distance measurement, they are popular in robotics and distance ranging. With so many uses and types, this article will guide you through key factors that will help you select the best ultrasonic sensor for your project.

Identify your application requirements.

Before you commit to exploring the different types of ultrasonic sensors out there, you can narrow down your choices by defining the requirements of your application. You can do that by focusing on the following factors:

Define your target object. What objects do you plan to measure with your ultrasonic sensors? The sensors can identify all matters of building materials, be they solid, liquid, or even certain types of gases. However, you should be mindful of the material’s surface texture and reflexivity since it can affect the sensor’s performance.

Setting your sensing range. Ultrasonic sensors are great measuring devices, but there’s a limit to how much they can do so. So before choosing which works best for your project, you need to identify the minimum and maximum distances that need to be measured by the sensors. From there, you can choose which ultrasonic sensors work best depending on their sensing ranges; Turck ultrasonic sensors are great for all-around materials, but you’re open to finding one that works best according to your project’s needs.

Check the accuracy and resolution. How accurate do you want your measurement to be? Be mindful of the accuracy and specifics needed, as well as resolution depending on what you will use it for, since some are more highly accurate than others.

Environmental conditions. Although ultrasonic sensors are versatile and great for all-around measurements, you should still consider the environment where the sensor will be used. Although most ultrasonic sensors fare well against environmental factors like dust and smoke, other factors should be considered, like humidity, temperature, and even ambient noise, to name a few.

Be mindful of your sensor specifications.

Once you have an understanding of the factors that make each ultrasonic sensor unique, you can now shop via specifications such as:

Operating frequency. Because ultrasonic sensors operate at different frequencies, check if you need to use higher ones or lower ones; higher frequencies are often used for shorter distances while the other is used for longer distances.

Beam angle. This refers to the cone-shaped area that the sensor can detect at an angle; the narrower it is, the more it can produce more accurate results.

Response time. This refers to how quickly an ultrasonic sensor can detect the object, as well as if the object undergoes any changes at a distance. This is crucial if the objects you’re measuring are in motion.

Housing material. Sensors come in different materials; the most common of them include stainless steel, plastic, or metal. Your ultrasonic sensor’s material type is crucial since it can be affected by environmental conditions.

Evaluate your sensor’s performance reliability.

From the aforementioned, you can already choose which ultrasonic sensors work best for you. But take into account its reliability and cost, as well as whether the manufacturer delivers quality after-sales service and technical support when using the sensor. Selecting the right ultrasonic sensor entails careful consideration, and by following the guidelines mentioned in this article, you can make an informed decision on which type of ultrasonic sensor works best for your project.
