A Hall-effect sensor is a transducer that converts a magnetic field directly into a usable electrical voltage. It enables ...

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 ...

C&K’s MPSR series of magnetic sensors are designed for non-contact position and proximity detection in tough dirty environments. The 61mm long housing is aluminium with a stainless steel cable, and ...

These magnetically operated reed proximity sensors can be supplied in standard PC board mount and stand-alone packages with virtually any type of connector, or can be totally engineered to ...

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 ...

Resistant to harsh environments, the MP1021 series magnetic proximity sensors claim to have a virtually unlimited life span. Said to be the first such sensor to allow users to specify the sensing face ...
