Our goal is to provide students, teachers, and researchers with the continuous flow of accurate data necessary to study and monitor the Ala Wai Canal. To accomplish this goal, we have built a new and improved version of the Ala Wai Catamaran (CAT). Our CAT allows its user to deploy buoys at specific locations in the Ala Wai Canal. Each buoy collects and transmits the temperature, pH, conductivity, and dissolved oxygen levels at that location.

Ala Wai Cat version 2

The CAT is designed to be both portable and efficient. The hulls are designed to optimize speed and allow the CAT to travel up to 4.5 mph. The CAT is also designed with removable modules which allow the operator to carry the battery and CAT separately.

The buoy

The buoy uses active positioning to remain at a set location in the Ala Wai Canal. Our three buoys each measure temperature, pH, conductivity, and dissolved oxygen.

Temperature Sensor

The Atlas Scientific Temperature Probe has +/- (0.15 + (0.002*t)) accuracy and reads temperatures ranging from -200˚C to 850˚C. The probe can be fully submerged in fresh water and salt water indefinitely.

Conductivity Sensor

The Atlas Scientific Conductivity Probe accurately measures electrical conductivity ranging from 0.07 to 50,000 μS/cm. The probe can be fully submerged in fresh water and salt water indefinitely.

Dissolved oxygen sensor

The Atlas Scientific Dissolved Oxygen Probe accurately measures dissolved oxygen at ranging from 0 to 100 mg/L. The probe can be fully submerged in fresh water and salt water indefinitely.
