| Notes: |
I tested the pressure sensor in the lab by lowering in ito a vertical column of ABS pipe filled with water. The sensor was lowered into the water at depths marked on the sensor's cable, then removed from the water at the same depths: 0, 25, 50, 75, 100, 125, 100, 75, 50, 25, and 0cm
The first test gave slightly higher readings than the second, but the third was between the first two, so I think all's well.
depth in meters = 1.4504 * mV - 0.1881
R2 = 0.9952 |
