This dissertation presents the project about the design and construction of measured size room. Using the ultrasonic can be measured in two directions. Is designed to measure the three forms, measuring distance, measurement, and the measurement volume.Found in measuring active during the 0.4-4.8 meter error is no more than 5% by testing all 3 test. The test phase has examples of the object surface to surface 4 type, a paper surface is wood surface is concrete and curve surfaceIn addition, this project can develop machine is small, compact, and the cost to create low.
