Weight sensor node
-
Hi!
Say I want to create a node that turns everything off when I fall asleep.
One option would be to use a heart rate / pulse sensor and when it goes below a certain amount, run the turn off action - but that will require me to wear the sensor.
Another (less accurate option) would be to know when I lay down on the bed, and after a certain predefined time - run the turn off action.Another scenario is that I want to know when there's new mail in the mailbox.
For this - I need a weight sensor node that can sense the weight change of the mattress or that there's new mail on the sensor in the mailbox.
I can't, however, find such a sensor. All I can find is a pressure sensor which seems to be barometric + temperature sensor...
Anyone knows of a weight sensor I can use for this node?
Thanks!

@Yveaux Perfect, thanks!

Put this underneath your mattress. It's a pressure sensor, add Mysensors door/window sketch, add timer to your homecontroller and switch off after timer runs out

Will that work as a weight sensor?
Couldn't understand from the description nor could I find the data sheet... -
Hi @hek ,
thanks for your answer. Unfortunately, this will not work for this application...

@Sefi-Ninio I was checking out MySensors videos on youtube one day and I stumbled on this one.
Cheap Bed Occupancy Sensor using Arduino & MySensors
I think this concept is exactly what you are looking for. I have thought about building this one myself. -
This looks great! Thanks a lot @dbemowsk !
