Circuit checks swamp cooler Water level: 10/31/02 EDN Design Ideas / (added 1/05) A "swamp cooler" is an
easy way to obtain effective air conditioning, especially in hot and dry climates, if a water source is readily available. Although most units are very reliable, the storage-reservoir control
usually uses a single level-detector component. Failure of this component can lead to serious water damage.... |

Water Level
Reference Design: 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.

Waterpump Safety Guard for Fish-pond: The circuit below was developed to guard the fish pond. In this case to prevent
that the pump sucks just air when the water level get below the pump. When the water filters get saturated and dirty, the water level behind the filter gets to an unacceptable level.
You can see this when the pump also produces airbubbles in the water... (added 2/06) |
