“A device that tracks, records, and alerts users to instances of potential sleep apnea via audio, visual, and vibrational systems.
Sleep Apnea threatens the lives and proper respiratory function of up to 20% of the global population, says The National Sleep Foundation, and 85% affected don’t realize they have it. In the image above, what looks like a mess of hot-glue is a device that tracks, records, and alerts users to instances of potential apnea via audio, visual, and vibrational systems.
Since I had hoped to make this device as concealed and small as possible since users would have to sleep near it, I knew the standard Arduino Uno wouldn’t work, as it usually doesn’t work for prototypes, and the ATmega328 wouldn’t be ideal because of its size. To these ends, my project incorporates the ATtiny85. Don’t be fooled. This IC packs a powerful punch, with ADC peripherals, PWM, eight pins, many of which I/O, and its size. Consequently, it’s perfect for small projects like SADD.”
