The water meter, designed by Team X, tests the water quality for the WetLands project. The design is composed of five sensors that read the volume, pH, salt water content via conductivity, temperature (Fahrenheit), and the flow of the water into the water tank of the drinking water on the barge. All of the values the sensors take are read by an Arduino programmable microchip and displayed on a liquid crystal display (LCD) screen. While displaying these values it will be saving those values to an SD card that is incorporated into the Arduino microchip.
The volume sensor is an ultrasonic ping sensor. The sensor emits ultrasonic sound waves that bounces of the water in the tank and reflects back to the sensor. From the time it takes to be emitted and the time it takes to return to the sensor depends on how far away the water is from the sensor. using a conversion factor that varies depending on the distance the volume is calculated and displayed to the LCD screen. All measurements will be displayed in gallons.
The pH sensor is an Atlas pH sensor that tests for acidity or basicity of the water in the tank. This sensor MUST be constantly stored in water or else it will break and need to be replaced. Also this sensor needs to be calibrated approximately once a week because it is constantly being stored in the testing solution and will need to be cleaned; however, if it is not being constantly used it can be stored and may last up to a year with out being calibrated.
The saline sensor is derived from a small volume/conductivity sensor. The probe will read a conductivity value and through a conversion find the parts per million of the salt concentration on the barge.
The Data Storage Shield uses an SD or micro SD memory card to track and store data trends that are being measured by each sensor.
