Sensor Physics

• Sensor will create a pulse of sound with a
  frequency of 40 kHz
• Senor will listen for a reflection or echo and
  from it calculate the distance
• The longer the interval between producing the
  sound wave and the return of the echo the farther
  away the is car

Sensor Physics

• Sound waves in air are called compression waves
  or longitudinal waves
• Sound waves can have different wavelengths,
  amplitudes, velocity, and frequencies
• Frequency number of times it oscillates in a
  second past a fixed point
• Frequency is measured in Hertz (Hz)

14
Sensor Physics

• Velocity wavelength / period
• V ? / T
• Period 1 / frequency
• T 1 / f

Sensor Physics
16
Sensor Physics

• Sound waves in the air
• Compression wave looks like a slinky
• Displacement in the air is parallel to the
  propagation of the wave

Benefit-Cost Analysis (2)

• With the opportunity of expanding into enhanced
  entertainment in the private home, there is no
  limit on the benefit of the system.
• Could receive corporate sponsorship for the
  system and sell the distribution of analysis to a
  corporation to then redistribute to the public.
• Sell the system to government for use in
  educational programs.
