They rebuild one of the most iconic components for an electronics tinkering beginner — an ultrasonic distance sensor, and what’s fun is, it stays fully functional after the rebuild!

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors.

Building an Arduino speed detector using IR technology to measure the speed of a moving object is much more cost-effective, ...

It always outputs a rugged distance signal and maintains a repeat accuracy of up to 3 mm. Featuring an integrated IO-Link interface in the latest version V1.1.3, this sensor is also ideally suited ...

optoNCDT 1220 sensors offer an excellent price-performance ratio combined with high measurement accuracy. They are particularly suitable for displacement, distance and position measurements in OEM ...

The iPhone's proximity sensor is one of its handier built-in features. When you raise your iPhone to your ear, its screen will automatically go dark due to the feature, saving battery and making ...

It also features the world's highest 2 laser irradiation density as a LIDAR sensor, enabling long-distance and high-precision object detection. LIDAR is expected to be essential to the ...

In a smartphone, a proximity sensor is located by the phone speaker. It turns off the touch detection during a phone call; otherwise a person's ear would activate functions when pressed against ...
