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 ...

[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. 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 ...

Infrared certainly has its uses, but if you’re trying to locate objects, ultrasonic detection is far superior. It’s contact-less, undetectable to the human ear, and it isn’t affected by smoke, dust, ...

This project is a simple modification of the LightGauge project. Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino.

A capacitive sensing evaluation kit from Cypress Semiconductor is being made available free to design engineers by distributor Future Electronics on its ‘My Board Club’ website. The CY3280-MBR3 ...

Adafruit has this week announced the arrival of the new VL53L0X Time of Flight Distance Sensor which is now available to purchase directly from their online store priced at $14.95. The new VL53L0X ...

Farnell element14 is offering the Analog Devices EVAL-ADICUP360 evaluation board with an Arduino form factor, which comes with open source development tools, software examples, and hardware modules.

Developers, makers and hobbyists building projects requiring distance sensors may be interested to know that the new Garmin’s LIDAR-Lite V3 is now available to purchase from online stores such as ...
