I have a couple of water tanks I need to monitor - a septic tank and an irrigation "weir box" that feeds our community irrigation system. I need to be alerted when the water depth either falls below or rises above (two) specific levels - basically want the "low" sensor immersed and the "high" sensor out of the water.
I have the sensors; basically just floats that open and close a connection an d have "bench tested" reading the sensors through GPIO ports on a Raspberry Pi; but I need to deploy them. I'm thinking of a PVC pipe with two floats attached to it at the appropriate levels and then mounted on the inside of the tanks. The septic system is close enough to the house so that I could run power (even POE); but the irrigation box has no power anywhere near it.
It looks to me like this would be a great application (or perhaps just an "Add on" to) for something like the Air Quality or Lightning Detectors); but, I'm a "Pi" guy right now and have not played with other microcontrollers or hardware.
So - some "newbie" questions: 1) Are there GPIO ports available on the Lightning or AQI boxes that could be used to add a "high" and "low" switch 2) If there are NOT ports available on those, what hardware bits would I need to purchase to duplicate the Lightning/AQI microcontroller so I could "roll my own" dedicated solar powered sensor package.
Any other suggestions to get me started would be great!
Thanks!

Great idea and I think you could do this. All the software is available.
1) There are GPIO ports available on the Lightning and the AQI boxes.
2) We will be selling these microcontrollers shortly. PM me to be notified when (a couple of weeks - have to write the specification!)
3) The question you aren't asking is how to send this data over the the Pi. The answer is there are some bits left over and so you can send more information. Look for AuxA.
