Through beam (or opposed mode) sensors incorporate a transmitter and a receiver on opposite sides of the target and evaluate absence or presence based on transmittance or blockage (respectively) of ...

Other considerations include cable material, emitted beam, modes of operation, body type and various features. Choices for optical configuration for fiber optic proximity sensors include through beam, ...

To make things easy, most modern utility meters have a pulsed LED output, which can be used to monitor the consumption by using an external optical sensor. But what do you do if your meter isn’t ...

The types of magnetic sensors that are currently available. How the magnetic sensors work. Applications for the different magnetic sensors. Position sensors enable a variety of functions and ...

Proximity sensors are common enough in automation projects that we hardly give them a second thought — pick something with specs that match the job and move on. But they can be fussy to get ...

We liked the YoLink Smart Window Door Sensors, LoRa ¼ Mile Range best and were impressed with its ability to transmit up to a quarter of a mile away. The best alarm for a particular shopper will ...

A sensitive upconversion nanocrystal-based biometric optical tactile sensor instantaneously and quantitatively decomposes dynamic touch signals into individual components of vertical normal and ...

Both sensors measure rate of change; they just measure the rate of change for different things. In practice, that means that an accelerometer will measure the directional movement of a device but ...

Just like smartphone cameras, these sensors have a finite resolution. The higher the resolution, the finer details the sensor can discern about your finger, increasing the level of security.

Sensors are devices that detect and quantify physical aspects of the world around us. The measurement can either be read directly or converted to a signal for processing by electrical, hydraulic ...
