Abstract: A digital electronic volume/flow control sensor toilet includes a bowl, a water storage tank interconnected with the bowl, and a digital electronic volume/flow control sensor flushing mechanism. The flushing mechanism has components including a volume sensor, a shuttle, a plunger assembly, a motor, a water valve, and a control with a power source and volume/flow control sensor circuitry communicatively interconnecting the components. The volume sensor has a plurality of electrically conductive contact points exposed on a surface and at positions along a length of the side of the volume sensor with a recess, the positions of the contact points corresponding to predetermined volume levels of the flushing mechanism. A plurality of VOLUME SELECTION buttons/switches are mounted on an outer surface of the water storage tank, the VOLUME SELECTION buttons/switches being associated with the contact points. A HOLD button/switch can be mounted on the outer surface of the water storage tank.
