I am on a bit of a fishing expedition so please bear with me. Surgery has left me having to sleep in a sitting position at about a 45 degree slope. A contoured foam wedge keeps me in position most of the time but I can either slip down or lie on my side. Either way reflux ends up in my lungs. This can lead to pneumonia. I would like to build a wearable sensor or set of sensors which could detect my change in position and give me a buzz if the position l lasts for more than a few minutes. I’m handy with electrical work but will need coaching on the electronic side. I see this as the last chance to avoid being strapped into place for the night. Thanks so much for any thoughts you might have.
