How to Measure Breathing with Radar and Arduino #Arduino

Thanks to Oyvind for sending in this tutorial! Oyvind writes:

A tutorial I wrote on how to do contactless measurement of my breathing with a radar module from XeThru and an Arduino.

The module was really easy to use. I connected it to my Arduino Uno using a breadboard.

It uses pulsed Ultra-Wideband technology: It sends out electromagnetic
pulses and measures the time it takes for the pulse to bounce back. And it’s extremely precise, so it actually measures the position of my belly with millimeter precision. Then it takes this measurement to control the
light-intensity of the LED I’ve connected.

The cool thing is that it can also see through things. So you could build it into a chair, a lamp, a wall, or whatever.

  1. Nice! What’s the max distance using the current sensor?
