Unit Testing Summary
1. Sensors: Before committing to the EZ-2/EZ-4 ultrasonic sensors, the sensors are tested to detect object of at least six feet away. Results of the test are shown in Table V. The first column lists the distance of the object from the sensor being tested. The second and third columns lists the measured outputs from the EZ-2 and EZ-4. The measured outputs from the sensors is converted fromt digital to inches using equation
2. In the sensors test, a cardboard box and a tape measure are used as obstacles.
