Salt Level Sensor

[KidSquid]

Is anyone familiar with a simple salt sensor I could use with my home automation system? I'm looking for a sensor I could attach to a ESP8266 or similar microprocessor that could report back salt levels to my home automation system. I'd love to get reports when levels cross x or y.

About a year ago I built a pressure sensor that attaches to my DE filter and reads the pressure and sends me an alert when it get's close to backwash time. The value is also displayed in the house on a status board that keeps household data in a central location.

Any suggestions would be greatly appreciated.

How about a continuity sensor that will report back through an Arduino , and can be used to calculate salinity.

In all honesty, unless you live where you get monsoons all the time, testing by hand is the best method. I've added about 5 bags of salt since my pool was built in 2013. Salt doesn't really go anywhere and doesn't play much of roll in the grand scheme of things. If your salt level is within the specified range that your SWG requires and that matches up with its internal reading, then it is happy and will produce chlorine. If your SWG reads something that is out of its operating range, then it will stop producing chlorine. If it reads 2500ppm and the actual salt level is 3500ppm, you can just add salt until the SWG is happy.

When the cell begins to fail on a SWG, the salt level is under reported. Often the pool owner will keep adding salt to the pool to get it working again, and by the time they accept that it’s time to replace the cell will have salt levels at 5000 or even more. So it’s not always as simple as “just add salt until the SWG is happy”.
