NozzleMon
The well-designed NozzleMon system monitors the pressure
and relative motion of the nozzle at the end of a water hose.
The NozzleMon then relays the information back to the pump
operator. A 13192-EVB serves as the controller in the pump
panel unit, which includes a 2 × 24 LCD to show pressure readings
and messages, a bright red LED for indicating problems, a
push button for indicating a set pressure, and a toggle switch
for turning on the power. An MC13192 SARD board serves as
the nozzle’s processor. Pressure sensing is achieved with
an MPXH6400 sensor. Position sensing is accomplished with
the x- and y-axis (MMA6261Q) and z-axis (MMA1260D) accelerometers
on the SARD board.
