Has anyone tried to find or make a zwave pressure sensor that can be calibrated to determine amount of milk remaining in milk jug?
I’m gonna follow this… I’ve got an idea for a baby monitor with this, if it exist.
It would probably be A zigbee sensor, and the container would have to be pressurized. There are a lot of Zigbee sensors for measuring liquid levels.
If you just want an Indicator for when you reach a specific refill level, a lot of people have already done something similar either for testing the water in a Christmas tree container or for testing the water level in a pet bowl. You can find discussion of both in the forums.
I think the OP was talking more weight than sensing the liquid level.
