This monitor will let you know if your CPAP mask comes off at night

Arduino TeamAugust 1st, 2019

If you wear a CPAP (Continuous Positive Airway Pressure) mask to treat obstructive sleep apnea, you may wake up to find that you’ve flung the mask off during the night or adjusted it to the point that there’s a large air leak. To help with this problem, Bin Sun has developed a CPAP monitor that measures air pressure via an MPXV7002DP sensor—often also used to determine the airspeed of RC models.

The device is controlled by an Arduino Nano, and when it detects improper pressure readings in alarm mode, it activates a small buzzer, displaying a “check mask” message. It can also be set up to run in manometer mode in order to observe pressure changes. 

More information—including required parts, print files, and code to make it run—can be found here.

    Awesome post. Thanks for providing the information.

    I would be very glad to buy this cpap alarm if someone would be willing to build one for me, per this article. It would be particularly great if the alarm was more than a simple buzzer, something with volume that I could adjust to be sure I’m awakened. I’ll be glad to provide my email address to someone who would like to continue this conversation one-on-one. Many thanks.
