“Uploaded project was designed and programmed by Rodrigo Mejas (Santiago-CHILE).
The product consists of measuring from a simple linear distance, square meters and up to cubic meters. Since we are using HC-SR04 ultrasound sensors, distances should not exceed between 3.5 meters and 4 meters long,and especially there should be no obstacles in the line that is registering the measure
According to the measurement that we select in the TFT screen menu, the LEDs will begin to flash indicating where each sensor should point, so that each distance registers the angle for square meters, cubic meters, or simply linear distance. After that, just make click on center of ROTARY ENCODER to Start collecting (“MEDIR option”) each distance. An single 3-axis graphic will show each measure and confrimed by each LED that stays ON. And according selected Option in menu Mts2 or Mts3, results will be shown on top right corner.”
