The best choices right now are the Kidde/Ring collaboration detectors ($75) that work with the Ring app for free, and the ...

Light sensors detect the presence or absence of light, and the intensity of that light. These sensors then convert light ...

Researchers at the University of California, Riverside, have uncovered how to manipulate electrical flow through crystalline ...

Imagine quickly diagnosing why your car's check engine light is on. A scan tool, also known as a trouble code reader, can help you identify the problem yourself.

We demonstrate a new detection scheme for a microfabricated flow cytometer. The fluidic-photonic integrated circuits (FPICs) that perform flow cytometric detection possess new functionality, such as ...

This is how anti-tamper devices work and what are the basic considerations for choosing the right tamper detection technique.

A tachometer uses a simple detector with a threshold detector to accomplish optical sensing using available ambient light.

The output is high when a person is detected, moving or not. The application using the radar module can therefore remain simple, as it only has to react to a binary state. Presence Detection Circuit ...

Researchers have made an important breakthrough in scaling quantum technology by integrating the world's tiniest quantum light detector onto a silicon chip.
