This Arduino radar tutorial explains how to control the brightness of an LED with your breath using a XeThru radar sensor module. Once both components are connected together, the RGB LED fades in and out with his breath, and also fades in and out faster as his respiration rate increases. This is also an experiment to get the XeThru radar to work with Arduino.
The XeThru video library provides a series of videos on respiration/sleep monitoring, occupancy/presence detection, tutorials, and client stories. Browse these videos for inspiration and helpful tips on how to get started with our technology!
