The first experiment was with pressure sensors, The above photo consists of a 0 - 5 psi transducer with a voltage output. the circuit uses a precision 5Vdc regulator to ensure stability during measurement. The team used a large syringe connected with a 7" length of 1/8" tygon tubing to simulate increased presure and noted the change in the output voltage with increase in pressure applied. A simular sensor will be placed on our "position microprocessor board" and we will use the pressure to calculate the depth of the submarine.
The data from the manufacturer's data sheet plus the experimental results were used to formulate the sensors reponse and calibrate our device to calculate depth
