A01NYUB Ultrasonic Distance Sensor

Q: <h3><span ><strong>What is the detection range of the ultrasonic sensor?</strong></span></h3>

<p>The detection range of an ultrasonic sensor depends on the wavelength and frequency it uses. The longer the wavelength and the smaller the frequency, the greater the detection distance. The following is the detection range of several popular products on our platform for your reference.</p><figure class="image"><img src="https://dfimg.dfrobot.com/62469707aa9508d63a41ca96/makelog/266dead0757a3d416694f553fe5c720d_0x0.png.webp"></figure>
