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 […]
wind sensor demo
Yesterday we managed to get the first wind sensor working. Together with Richard I connected the sensor to the RBBB board, calibrated it and read some wind/breath data from the serial port into Processing. It works surprisingly well: I have already noticed that the distance from the sensor to the nostrils is critical. I’ll have […]
