So we’re using a 30bar pressure sensor to measure changes in the depth of water in a tank. We’re using the 2" acrylic tube enclosure with one end cap with no holes and the second end cap with two holes: one for a cable thruster for an Arduino Nano and the other for the pressure sensor.
The Arduino Nano, reads from the pressure sensor, which is supplied with 3.3V through a LLC. The code we’re using is the default example given on the bluerobotics site. The sensor gives reasonably accurate values in air and water. However the catch is that when the enclosure is dropped into the water at even a marginally fast rate i.e. 0.5 m/s or greater it gets stuck. i.e. we get one constant unchanging value for depth. Normally we would expect the value to fluctuate marginally given the high sensitivity of the sensor. In contrast, if we lower the enclosure really slowly the readings respond well and show the new depth (with a little fluctuation)
How would you recommend we troubleshoot this?
