I see where the town where Texas had floods and people died, they have installed flooding early warning devices. I had built my own over the winter, and I am adding several more devices at key flood areas on our property to warn us when to move our cars, when to get things out of the yard and from the sheds, etc. My guess is that the ones in Texas are pretty expensive. I can do it for just a few bucks a device by using repurposed 4x4 vinyl fence posts, very cheap float switches, and an Arduino I wrote my own firmware for. I would like to see about installing a few around the island at different key areas so that others could benefit from an early warning system without having to break the bank for the devices. #arduino #raspberrypi #iot #weather #emergencies
