A study explores how praying mantises detect motion during prey capture. Animals possess the ability to detect both first-order and second-order motion. The former involves tracking changes in ...

Studying mice, scientists have identified a neural circuit in the retina that carries signals enabling the eye to detect movement. The finding could help in efforts to build artificial retinas for ...

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 ...

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 ...

IR sensors rely on an emitter (IR LED) and a detector (photodiode or photoresistor) to measure infrared light and convert it into electrical signals. There are two main types of sensors: ...
