The Application of Ultrasonic Sensor and Atemega 328 Arduino to Measure the Ploughing Depth Elevation of Drainage Channel

The measurement of ploughing depth is still carried out manually using ruler which pinned down into the soil through leg fissure and its narrow leg. This practice is considered as non-valid measurement. Therefore, an improved measurement should be developed such as using ultrasonic sensor. The objective of this research was to (a) develop automatic mole ploughing depth elevation measurement, and (b) gain the deviation magnitude resulted from set point and ploughing depth elevation position. Ultrasonic sensor was permanently attached heading to the target. A plat was attached onto hydraulic support. The sensor will detect the ploughing depth-distance when the hydraulic lifting or lowering the mole plough. As shown in the result of ploughing depth elevation, it could be seen that ultrasonic distance sensor was appropriate to detect the ploughing depth. The deviation occurred at M, N, O and P tracks with magnitude of 0, 99 %; 1, 04 %; 0, 63 % and 0, 87 % respectively.
