Integration of Water Control with a Drip Irrigation System for Agricultural Application

Most drip irrigation systems are controlled and set with an estimated watering duration. However, this requires that the water source has a constant water flow to ensure correct water distribution. Farms that need a drip irrigation system but does not have a capability to provide and maintain constant water flow requires precise and active water control. The research covers the creation of a drip irrigation system that can adapt to variable water flow input. It includes the hardware and software development of the system, calibration of sensor, testing, and comparison of the water usage based on system log and the actual water dispensed. For this system, a turbine flow meter with Hall-Effect sensor was used. The research does not comprise of the observation of farms or crops where the system will be applied. With the experiment, the results have shown that trial samples from the System Log and Actual water used are the same and does not have a significant difference. Thus, it is concluded that the system provides the precise amount of water output based on the threshold.
