The Water Level Reference design continuously monitors water level and water flow using the temperature compensated MPXM2010GS pressure sensor in the low cost MPAK package, a dual op–amp, and the MC68HC908QT4, 8–pin microcontroller.
Demonstrate Water Level Monitor plus additional features such as water flow monitoring and leak
This system uses very few components, allowing for a solution to compete with a mechanical switch for water level detection, monitoring water flow for leak detection, and other applications for smart washing machines.
