Here is a motor speed sensor module, the major goal is to check the rate of an electric motor. The module can be used in association with a microcontroller for motor speed detection, pulse count, ...

A COVID-19 sensor developed at Johns Hopkins University could revolutionize virus testing by adding accuracy and speed to a process that frustrated many during the pandemic. In a new study published ...

This one is almost too simple, but it might come in handy. It turns out that Pabst fans (and probably several others) already have the circuitry for RPM monitoring. Pop it apart allow pcb access and ...

Smith Systems designs and manufactures ultra-high reliability sensors for monitoring speed, motion and temperature of railway components. The company supplies ISO 9001 and IRIS certified standard and ...

Researchers created a flexible sensor platform that detects gases and measures their movement speed through nanomaterials, enabling new applications from breath analysis to security.

So I just bought this nice new switch off Ebay for cheap and it has 4 very loud fans in it. I'd like to replace them with lower noise (and lower flow, I'll take my chances) fans so I can hear myself ...

The Problem with sequels, especially ones that follow a huge box-office success, is that it's difficult to reproduce the original magic. Arguably the most influential movie ever made (at least ...

The facility, based in Italy, is the first of its kind outside the US and will be used to support the G550 aircraft modifications alongside other air, surface and maritime platforms. L3Harris has ...

STAr Technologies Inc, a leading supplier of semiconductor test probe cards, today announced the introduction of its new MEMS type micro-Cantilever probe card - STAr Aries Sigma-M, designed and ...
