Falconeddy:
I am using a Ping Ultrasonic sensor mounted above my sump pit. The Arduino UNO has a wifly shield that posts the data to a Cosm feed. The sketch sends a notification to Prowl when high water is sensed. I can monitor the feed on my mobile device as well.
Hi Falconeddy
Would you mind sharing some details of your project
I currently have 3 float switches and would prefer to replace them with some kind of level sensor. how reliable is the ping ? Did you put in a pipe in the sump pit and measure level in that, or just have it face the bottom of the pit. I have two pumps in mine, so there's not a lot of free space
