Step-by-step guide on designing and programming a custom I2C slave sensor device using Arduino..

RPS-429AA-40P-IS2 intrinsically safe (IS), ultrasonic sensor achieves precise accuracy in distance measurement and object detection applications. With ATEX, IECEx and C-UL-US certifications, this ...

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 ...

Ultrasonic sensors are unique devices that harness ultrasonic waves to measure distance, detect objects and analyze material properties. Their distinctive mode of operation, advantages and ...

Sometimes, it’s time to shut down the oscilloscope, and break out the cardboard and paints. If you’re wondering what for, well, here’s a reminder of an Instructable from [CrazyScience], that brings us ...

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 ...

If you're into robotics or electronics, you've likely come across Arduino—a small microcontroller that can control sensors and motors for nifty DIY projects. Like the Raspberry Pi, the Arduino is ...
