Today’s invention offers a way to waste less water during toilet flushing.
A load cell in the seat monitors the weight of material deposited in the toilet bowl as a function of time (by the decrease in weight on the seat).
Urination would be detected by a longer duration unloading (and ignored by this mechanism), whereas defecation would be signalled by more intermittent unloadings (you get the picture).
This allows the system to determine whether an intense flush is required (characterised by a single, large unloading event) or if the usual, small flow will suffice.
