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. This system uses very few components, reducing the overall system cost. This allows for a solution to compete with a mechanical switch for water level detection but also offer additional applications such as monitoring water flow for leak detection, and the other applications for smart washing machines. http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=RD1950MPXM2010GS&parentCode=null&nodeId=0MFB28tn7z |
