| Summary: | In this final project has made prototype system water level measurement and
control at flow stream area based on Arduino Uno and LabVIEW interaction with 2
ultrasonic sensors SRF05 as measure of water surface distance and servo motor as
water gate operator based water level comparison.
The first ultrasonic sensor is measuring water surface distance at primary /
first stream area and the second ultrasonic sensor is measuring water surface distance
at diversion / secondary stream area. Ultrasonic sensor is measuring distance every 1
cm multiple. Distance measured from every ultrasonic sensors state as distance
variable. Arduino Uno has sending distance variable 1 and distance variable 2 to
LabVIEW. Distance variable 1 and distance variable 2 were converted become water
level 1 and water level 2 from calculation process on LabVIEW. Water level 1 and
water level 2 were compared and assumed as difference level with calculation water
level 1 subtracted water level 2. If water level 1 equal with water level 2 then radian
angle of servo motor at 0° position and water gate still close. If water level 1 higher
than water level 2 then radian angle of servo motor moving at radian angle n°
position and water gate open, then water from primary stream area was distributed to
diversion stream area.
Water gate is open at bottom level, intermediate level and high level
accordingly water level comparison condition. Servo motor is controlled in automatic
or manual from LabVIEW. Radian Angle of servo motor at every condition is
decided by LabVIEW and will be sent to Arduino Uno for moving servo motor. |
