Ultrasonic sensors have been a staple in the sensing space for several decades due to their capabilities, flexibility, and low cost. As the rise of IoT finds its way into virtually every market and ...

Although ultrasonic sensors have been around for several decades, their popularity in sensing applications continues due to their capability, flexibility and relatively low cost. Products like ...

Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

Some photoelectric sensors, ultrasonic sensors, and rotary encoders generate a digital dc output called a push-pull signal. The external environment activates the sensor, which, in turn, closes a ...
