[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.

We’re used to Hall effect devices as proximity sensors in mechanical ... The circuit is extremely simple, comprising the sensor, an Arduino Nano, and an OLED display. This device is handy ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

The store points to the LILYGO LoRa Series’ GitHub repository with Arduino samples for LoRa P2P communication, LoRaWAN, display, sensors ... SoftRF general aviation proximity awareness system ...

Likely applications are button designs and proximity sensing. The kit’s board also includes ... The kit works as a stand-alone unit and as an Arduino-compatible shield. It can be used to add a ...
