I have been working on my Sump Pump Alarm project again, and I have come up with the wicked awesome Sump Alarm Warning Loud Alarm Bell (SAWLAB) to let me know when the pump isn’t working and the basement is about to flood. Here is what it looks like.
Here’s how it works: When the sump hole fills with water, the Float Switch in the Sump Hole floats to the top, which causes the float switch to close the circuit to the battery pack, which sends 12 Volts to the bell circuit, which makes the Alarm Bell ring. Here is what it sounds like.
Pretty cool, hunh?
What? Of course everybody cares. Just look at how fast the hit counter has been going up recently.
