Depth Sensor v2

6th March 2020

Taking measurements of water pressure can be used to calculate the depth at which the reading was taken. The sensor compares the pressure of the water to the atmospheric pressure allowing it to output a relative reading of the water pressure. This permits us to take an reasonably accurate measurement of the water depth.

We have two similar depth sensors that output either an analog or i2c signal both of which can be received by most micro-controller devices.

To allow for calibration and testing of the depth sensor, a 3D-printed housing was required. We also incorporated a EC mount into the design. There were a few attempts of the probe housing of the past weeks.
