Abstract
A wave control circuit disclosed herein may be used to control the operation of various plumbing devices and appliances. The wave control circuit uses a sensor to sense presence of objects in the vicinity of the plumbing device and appliance using the wave control circuit and a control circuit to control the operation of the plumbing device or appliance.
Claims17
An apparatus for controlling operation of a plumbing device, the apparatus comprising:
- a sensor device adapted to detect movement of an object in its sensing field and to generate a sensing signal;
- a control circuit adapted to:
- generate a timing event in response to the sensing signal,
- generate an enabling signal to enable a valve in response to the timing event,
- calibrate the sensor device after a delay following the enabling of the valve,
- determine if the valve needs to be disabled by starting an automatic timer after calibrating the sensor, and at least one of determining if there is an object near the sensor and if the timer has expired, and
- generate a disabling signal to disable the valve.
