I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

[Dustin Andrews] built this add-on board which works as a proximity sensor. He wanted a standalone sensor for his Arduino projects which would use a single pin as a trigger. This lets him alert the ...

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 ...

Getting a magnetic field to balance on another magnetic field is about as easy as balancing a bowling ball on the tip of an ink pen. With a little help from an Arduino mega, however, [EmmaSong] was ...

New MFxM magnetic proximity switches detect magnetic fields over large distances up to 60 mm. These sensors can be used effectively in applications where the target is located behind a wall of ...

C&K has expanded its offering of magnetic proximity sensors to enhance flexibility and reliability for non-contact position and proximity detection in tough environments. Featuring a ruggedized ...
