Time-of-flight (ToF) sensors open up new application areas and use cases for proximity sensing and presence detection technologies, and these sensors can add valuable functionalities and intelligence ...

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 ...

The options when specifying sensors for long-range object detection or positioning usually boil down to two alternatives: optical sensors using either infrared or visible-red light and ultrasonic.

SU, UK, UT and TU series round body and UQ series cubic plastic ultrasonic distance sensors from AutomationDirect are now available in sensing distance ranges from 60mm to 8000mm, in metal or plastic ...

The following guide provides a review of the types of proximity sensors for prolonged detection, followed by a look at capacitive sensing design specifically for occupancy-type solutions. A variety of ...

The sensitivity of the proximity sensor circuit can be adjusted with P1 for the desired “distance”. One of its obvious uses is to open a door automatically. For this the sensor must be placed on the ...

Electronic enthusiasts may be interested in a new open source infrared sensor which has been created to support both Raspberry Pi and Arduino powered projects. The IR Detector proximity sensor has ...

Double sheet detection where consistent and reliable detection of one or more layers of materials such as; foil, paper, cardboard, labels or even thin metal sheets can present complex challenges. If ...

This video shows the working principle of the advanced ultrasonic sensors from Physik Instrumente (PI). Developed for flow measurement and bubble detection, the PI ultrasonic sensors are ...
