I’ve been thinking about making some sort of sensor to detect if I’m in bed or not.
I work out of town a lot, and on top of that I work nights, so my schedule is off the map. At 4am or 4pm I may or may not be home, I may be awake, asleep, just going to bed, or just getting up, so I can’t use calendars, alarms, time, bayesian, etc.
So I want to make a sensor I can put under my mattress or something to trigger going to bed/getting up automations, but I’m not sure the best way to go about it.
Would a FSR be the best way? Or load sensors under the frame? If I go with load sensors, could I wire up the ones out of a cheap bathroom scale? I’m not too familiar with tinkering with electronics but this little project would be as good a beginning as any.
Googling found some projects where people built sensors for a sofa using FSR’s to trigger a “watching tv” or whatever scene, but I’m not sure if it’s scalable to something queen bed sized.
Any ideas? Thanks!
