Some motion sensors are based on optical measurement technologies to provide accurate velocity and position measurements without requiring physical contact with the object or surface being monitored.

Researchers will report a new laser-based sensor that effectively detects buried objects even while the detector is in motion. This new device offers a significant improvement over existing ...

Astronomers have identified 27 potential new planets orbiting binary star systems, more than doubling ...

The new smart sensor uses embedded information to detect motion in a single video frame. A new bio-inspired sensor can recognise moving objects in a single frame from a video and successfully predict ...

Researchers at the Georgia Institute of Technology have created a passive motion/contact sensor that detects motion using ...

The IWR6843 sensor IC series enables close-range sensing of objects, people, and motion with high accuracy and resolution, and with higher-precision results than existing 24-GHz systems. It wasn’t ...

Unlike infrared optical sensors that use an LED transmitter and IR receiver, the PIR emits nothing. As its “passive” name suggests, it responds only to infrared energy radiated by the object being ...

Motion detection is the magic ingredient in the current wave of do-it-yourself home security cameras. Thanks to built-in sensors that vigilantly monitor their field of view for movement, you can go ...

Wi-Fi sensing, which uses Wi-Fi signals to detect target behavior, has been gaining attention in recent years, and was standardized in the Wi-Fi standard ' IEEE 802.11bf ' released on September 26, ...
