The Aqua Monitoring System (AMS) is an innovation in water quality monitoring technology. The AMS 1.0 is to be attached externally to the hull of a vessel and completely submerged under water, where it will sense various aspects of water quality through an interchangeable set of sensors. Potential sensors include, but are not limited to, temperature, salinity, pH, dissolved oxygen, turbidity, and water composition sensors. The sensors will automatically check qualities of water every few minutes; all probes are connected to an Arduino microcontroller, which is connected to a GPS tracking device. A turbine inside of the body provides the apparatus with a sufficient amount of electricity. Fisheries would be able to use the AMS to test waters for hazardous pollutants. The AMS is small in size, versatile, and open source making it the perfect apparatus for scientific research, as it is easy to interchange sensors and alter code. Currently, water research an unnecessarily long and expensive process, as scientists must create their own device for such purposes. The AMS has the capacity to confirm the accuracy of data sent from buoys. Finally, the apparatus can be used in emergency situations, such as oil spills, to track the extent of the disasters and the locations affected. With its multitude of applications, the Aqua Monitoring System has the potential to advance water quality monitoring technology and provide a springboard for future water-related scientific research and progress.

Step 1: Gather Materials

Two foot, Six inch diameter PVC pipe

Three by Two foot rectangular wooden board

Six double A batteries


Electric Motor


Hot Glue+ Hot Glue Gun



Step 2: Frame

First, build the frame. Cut out a parallelogram-shaped piece of
water-resistant material.

Step 3: PVC

Glue/screw on a PVC pipe. Cut out and glue/screw on pieces of
material of the following shape:

Step 4: Structural Support

This is made in order to hold the structure in place. Attach
pieces like the one shown above along the PVC pipe in at least three places:
one in the middle and (at least) one on each side.

Step 5: Turbine

Make a turbine. This can be done using plastic from objects like
gallon water bottles. Cut out each wing and make thin crevices in a wooden or
plastic rod. Place and glue the wings into the rod. Drill a hole on each side
of the AMS such that the holes are directly opposite each other. Insert the
turbine through an opening in the PVC pipe and place it through the holes.

Now, attach the motor which will provide power for the AMS.
Attach a platform to the PVC pipe, if necessary; on it, place the motor. Attach
the tip of the motor to the turbine so that the motor spins when the turbine is

Step 6: Electronics

Next, attach the probes. Drill holes within the PVC pipe; place
in the probes from whichever sensors you choose, and make the hole water tight
using grommets or other seals.

Attach the electronics. The electronics includes the Arduino (or
other microprocessor), a GPS location device (if necessary), and batteries.
Glue the electronics throughout the main body, and, using wires, solder it

Step 7: Outer Covering

in order for the AMS to be able to be used underwater, it is necessary to have
a half-egg shaped cover. The final AMS should look similar to this:
