pH

1. Recalibrate to acount for pH 4 discrepancy
2. Recalibrate to account for temperature difference
3. Test together with nutrient meter

EC

1. nutrient meter

Temp

1. Plots

• Still pending data to prove that the sensor works.
• Compare measured data curve to data curve from manufacturer
• For calibration curves, show the 30 readings per value and plot into the graph as an error bar (remove the auto average code from readings code)
• If possible, plot against the raw input (like the raw voltage or 0-4096 from analogread)
