infrasound sensors, web cameras and GPS receivers. The system is geared toward both detecting a lahar should the volcano wake up in the future and the specific scenario of a lahar triggered by a ...

Linear velocity sensors measure the linear velocity of an object using either contact or noncontact techniques. Important performance specifications to consider when searching for linear velocity ...

They unraveled the mystery behind the seismic signal by combining data from seismometers, infrasound sensors, field studies, ...

A little over a year ago we’d written about a sub $100 muon detector that MIT doctoral candidate [Spencer Axani] and a few others had put together. At the time there was little more than a paper ...

Safety sensor switches are used in machines and other industrial applications to prevent accidental contact with live electrical connections. Safety sensor switches work together with hinged, sliding, ...

SPECIFICATIONS: This infrasound monitor uses microbarometer design. It incorporates a differential pressure sensor with 1/8 inch ID tubing connection, with one port located on the side of the box.

Carbon monoxide poses serious health risks and can be hard to detect at home without proper equipment. Keep your family safe with these expert-tested detectors. Laboratory Technical Project ...

While none of the water leak detectors we tested truly stood out among the others, our favorite model among this type of water leak detector is the Flo by Moen Smart Water Detector. In addition to ...

Our top picks for the best smoke detectors Best overall: X-Sense SC01 - See at Amazon Runner up: First Alert PRC710 Combination Smoke and Carbon Monoxide Detector - See at Amazon Best dual-sensor ...

Carbon monoxide alarms use a variety of detection methods, and the kind of sensor is often directly related to the power source. Keep in mind that carbon monoxide alarms can also include smoke ...

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 ...
