I’m working on the breath detection software and the device design. I’ve concentrated on detecting the breathing in and out and the event between breaths. Especially the distinction between in and out is hard as there is wind flow in both cases. So I use the difference in temperature to detect the in and out. […]

device and software
I’m currently developing the device design and the software for breathing_time. I realise now that the form factor of the device must come from the possibilities of the wind sensor. It works best when the breath is guided to the sensor. That way I can detect inhaling and exhaling. I’ve been trying out different sizes […]
First sensor
Hmm, this afternoon at the lab was a bit frustrating. As a starter a lot went wrong with the purchase of the two AppliedSensor sensors and the temperature sensors. My order went wrong, twice. It was a national holiday on Thursday so I feared that the stuff wouldn’t be in by Saturday. But finally, at […]
