 ====== Sump pump Monitor ======
+{{ :projects:electronics:sumppump:arduinosump.jpg?direct&300|}}
+<WRAP left round box 60%>
+My parents have a cistern and a sump pump which would be useful to have some sort of water level monitoring.
-<note important>Update pending</note>
+In the past, we would check the cistern level with a pressure gauge calibrated in inches of water. There was a rubber squeeze bulb which which would pressurize a plastic line which fed into the cistern, and the resulting level would be shown on the gauge.
+In order for the sump pump to be monitored accurately, the plastic hose from the pressure sensor must be slightly above where the water level when the pump turns off.
+The Cistern hose is connected to a small air pump which is cycled occasionally.

+===== Sensors =====
+Sensors on this board include:
+  * MPX5050 - Measures up to 5 metres (200 inches) of water (Used for the cistern)
+  * MPX5010 - Measures up to 1 metre (40 inches) of water (Used for the sump)
+  * 2 Optically isolated inputs, one input is triggered when the sump pump turns on, the other is not used
+  * 1-wire network for temperature sensors
+  * Thermistor
