The power switch with infrared proximity sensor is intended for the recognition of obstructions at distances of a few millimetres to a few centimetres. This compact sensor switch can be used to open a ...

This MEMS-based on/off switch is triggered by impinging IR photons, and remains in a zero-power quiescent state until that event takes place. Even the minute amount of current needed in slow, ...

STMicroelectronics is launching a human-presence and -motion detector to enhance security systems, home-automation equipment, and IoT devices that typically use passive infrared (PIR) sensing. The ...

The OPB725 Series long-distance reflective switch has a sensing distance of 24 in. or more, depending on the object. The switch consists of an 850-nm infrared LED and Photologic sensor in an opaque ...

A team from the Northeastern University has developed a sensor that requires almost no power to work and operate. Made for the US Department of Defense's Darpa (Defense Advanced Research Projects ...

Jim Dockendorff of MadisonSensor explains what to look for when selecting liquid level sensors and flow detection solutions.

Recently, the progress of uncooled infrared (IR) sensors has been remarkable due to microelectronic systems (MEMS)-based pixel structure, in which free standing thermal isolation structures are ...
