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 ...

This home smoke detector circuit warns the user against fire accidents. It relies on the smoke that is produced in the event of a fire and passes between a bulb and an LDR, the amount of light falling ...

In the future, the team's sensor could also be improved further; for instance, to support the identification of an even wider range of materials and the detection of more types of tactile information.

Technically, what [Alex] built is better called a “seismic detector” since it’s not calibrated in any way. It’s just a simple sensor for detecting ground vibrations, whether they be due to ...

A finger biometric sensor assembly may include a finger biometric sensor integrated circuit (IC ... set forth herein The idea of a Touch ID sensor embedded into the power button has always ...

But if you were looking for even more proof that Apple is at least exploring the idea of a bezel-less iPhone with a Touch ID ... sensor panel (referred to collectively herein as a “circuit ...

By connecting the sensor to a circuit board and an Arduino module for real-time data transmission, we've made it perfect for portable and onsite detection. "Our ultimate goal is to reduce the ...

Researchers have now developed a novel sensor that enables the continuous, and real-time detection of solid-state ... interface via a flexible printed circuit board, providing continuous ...

Finally, the team developed a source technology for a broadband active nano-spectral sensor, allowing tailored detection of specific substances using a single device, by widening the nanogap to the ...
