Hi Bob (and anyone else with an electrical/electronic bent), how do you fancy another challenge...?
I've been putting more pumps in place this week, and adding an early warning system (not quite working because of an old duff transformer which a mate is specing a replacement for me) which I'll share when complete, but I've also been thinking about how I could do something even more clever.
Sadly I have the idea but not the knowledge (currently) on how to execute...
I was wondering whether it would be possible to create, using the same frugal a minimalist methods as you shared here a sensor that could be set at a certain depth in my various water collecting/pumping chambers, and detect a rise in level and alert me?
The one I mention above involves some existing float switches which, when tripped, turn on orange strobes (one per pump) but I wondered if it would be possible to be a bit more clever and have something that could text/email me, or even, using some kind of smart switch, have Alexa announce to me that the sensor has been set off...?
What you reckon, up for the challenge, or at least helping me to investigate how it might work...?
