1. A water-flush toilet comprising
a toilet bowl in fluid communication with a water source;
a monitoring system comprising an ultrasonic sensor having a transmitter and a receiver, a secondary sensor, and a microcontroller electrically connected to the ultrasonic sensor and to the secondary sensor; and
a flush valve electrically connected to the microcontroller and disposed between the bowl and the water source,
wherein
the monitoring system is configured to perform a monitoring cycle, the cycle comprising
transmitting an ultrasonic signal towards a bowl contents of the toilet bowl, receiving the ultrasonic signal, determining a Time of Flight (ToF) measurement of the ultrasonic signal, electrically conveying the ToF measurement to the microcontroller, and determining a bowl status corresponding to the ToF measurement,
the secondary sensor is configured to detect a presence of a user on or in a proximity of the toilet bowl, and
the microcontroller determines the bowl status by comparing the ToF measurement to a normal bowl water level ToF measurement.
