Abstract

Plants are living things that are the main sources for other living things. It contributes the important resources to humans which are oxygen and food supply. But in the life process of the tree, it needs four basic things in their life: water, sun, nutrients and carbon dioxide. In complementing these four things, water and nutrients become a problem for many farmers and people who plant trees just as a hobby. This is because watering and fertigation must be done regularly according to the plant’s needs. Time constraints and many trees also cause irrigation and fertigation cannot be done properly. In solving this problem, automatic irrigation and fertigation devices are needed to develop. The main components for this project are soil moisture sensor, electrical conductivity sensor, water pump, power supply, multiple relay channel, and the most important are, Arduino UNO. Arduino UNO will act as a microcontroller to deliver data from sensors to devices to get the desired output. One of the sensors used is Capacitive Soil Moisture sensor that will detect the level of soil moisture that have been setup in the coding uploaded in the Arduino while Total Dissolved Solid sensors used for fertigation systems can detect the conductivity value. The programming system is built using Arduino software by implementing the required system. The pump to irrigate water and fertiliser worked as output of the systems. Both irrigation and fertigation systems are built separately but will work simultaneously. In order to make sure that the prototype of Arduino Precision Farming can be used as intended, it will be put through function testing. Before that, the sensors correct parameters were established using calibration code written in the Arduino IDE. The performance will then be evaluated by comparison with a few readily available devices on the market. Thus, the development of the prototype for Precision farming irrigation and fertigation is completed.
