This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

Check out the Avnet element14 competition In Reach! It's an "Ultrasonic Sensor Sensing Challenge". Ultrasonic The idea is for makers to build projects using TDK’s waterproof ultrasonic range sensors.

The U-GAGE T30UX ultrasonic sensor targets challenging applications with its extended functional range and advanced temperature compensation plus it features a robust U-GAGE housing to resist harsh ...

Inductive sensors are non-contact proximity sensors that detect ferrous targets, ideally ones made of mild steel thicker than one millimeter. They consist of four major components: a ferrite core with ...
