The length of the transformation line (12.1) is such that the imaginary component of its impedance is the same with and without an object present. USE/ADVANTAGE - Operates continuously and can detect presence of metallic and non-metallic objects even under conditions of high humidity and fouling.
Disclosed is an embodiment (50) of an optical sensor device adapted to detect presence of an object by reflected radiation such as visible or invisible light within viewing field (8) of an optical sen

Second, for some specific conditions, vision-based force sensors are irreplaceable when the contact force sensors find it challenging or impossible to detect the microinjection force [46]. Third, by making use of the microscope in the microinjection system, they can provide the force information ...
Turbulence is a complex and chaotic state of fluid motion. Atmospheric turbulence within the Earth’s atmosphere poses fundamental challenges for applications such as remote sensing, free-space optical communications and astronomical observation due to i
Highly reflective surfaces are notorious in the field of depth sensing and three-dimensional (3D) imaging because they can cause severe errors in perception of the depth. Despite recent progress in addressing this challenge, there are still no robust and
Object/spot detection is used to detect the activity or presence of an intruder at a single location. It provides direct security for objects. Such a detection method is the final stage of an in-depth system for protection. The objects most frequently protected include safes, filing cabinets,...
Measurement of height with a non-contact method can be performed using a proximity sensor. A proximity sensor is a noncontact-type sensor that detects the presence of an object. Proximity sensors can be implemented using different techniques such as optical, ultrasonic, Hall effect, capacitive, ...
So, we have covered pretty much everything that we need to know about using the HC-SR04 Ultrasonic sensor with Arduino. It’s a great sensor for many DIY electronics projects where we need a non-contact distance measuring, detection of presence or objects, level or position something etc. ...
A television may use an ambient light sensor to adjust the brightness of the picture to match changing room conditions. Even something as simple as a doorbell button acts as a rudimentary sensor to detect a human presence at the door.
