Wifi Sensor System

For best results it's good to do a 2 point calibration. The nitrate sensor would need to go into a 1 mg/L solution, you'd wait 1 minute and then press the calibrate nitrate 1 mg/L button in an app. You'd repeat for nitrate 100 mg/L, ammonium 1 mg/L, and ammonium 100 mg/L. Right now I have an android app that does all the calibrations when on the same wifi network. Attached is a screenshot of the app.

I still don't have definition on cartridge lifetime and cost but am working on getting that information.
