Once you have a track and a kart to race on it, what’s missing? A lap counter that can give your lap times in hardcopy, obviously! That’s what led [the_anykey] to create the Arduino-based Lap Timer to ...

A typical reflective object sensor consists of an infrared light emitter diode (IRED) and an NPN silicon phototransistor mounted side-by-side on parallel axes in a compact black plastic housing. The ...

An 880-nm AlGaAs infrared emitter (IRED) and a NPN open-collector photo device (photo-IC) are mounted on a custom, four-leaded TO-72 header to make up the CL1700 Reflective Object Sensor. The IRED ...

Some robots can swim. Others can kick, fetch, jump or fly. But the latest development in the field of robotics lets machines carry out an activity that is somewhat less athletic: plugging in a USB ...

Australian scientists are working on a new type of sensor that can locate wandering objects - including that missing coffee mug. Known as FLECK Nano, the sensors are small enough to be attached to a ...

Using a 3D-printed material sensitive to electric fields, researchers have created a novel sensor that can accurately recognize and distinguish objects up to 10 centimeters – about four inches – away ...

For agricultural and construction machinery applications, ‘Ground and Crop’ radar sensors deliver superior crop penetration and ground detection, while multi-object radar sensors allow individual ...

According to the National Safety Council (NSC), as many as 40,000 people died in motor vehicle crashes in the U.S. in 2016, the highest total in more than a decade. Among the main causes were speeding ...
