INTRODUCTION
1.1 Introduction
Water is required for the basic growth and maintenance of plants. When a sufficient amount of water is not present for plant needs, then stress can occur and the
quality of plants will decrease or plants will dead. Irrigation is common in Malaysia landscapes because of sporadic rainfall and the low water holding capacity of sandy soil.
This inability of many of soils in Malaysia to hold substantial water can lead to plant stress after only a few days without rainfall or irrigation. In order to overcome this
problem, Intelligent Agricultural Sprinkler System is used. This system based on method of applying irrigation using sprinkler which is similar to natural rainfall. Water is
distributed through a system of pipes usually by pump. It is then sprayed into the air through sprinklers so that it breaks up into small water drops which fall to the ground.
One mode is used in this project which is automatic mode. Automatic mode operates when soil moisture sensor detects the dry soil conditions. This automatic also
mode can be used according requirement such as for supply the fertilizer in soluble form and herbicide to control weed or as cooling system for greenhouse. This system is
controlled by using programmable microcontroller PIC. This system use sensor based
technology to automate irrigation that can improve water usage efficiency. Soil moisture sensor is needed to control the water pump of automatic watering system. Once the soil
moisture sensor detects the dry soil conditions, the sprinkler head will be function by control the PIC. This system improved the irrigation system from manual to automatic to
make the farmers easier to monitor the soil condition of the plants.
1.2 Objectives:
The objectives of the project are important to ensure the research will fulfill the solution of the problem research. All the objectives are shown below:
a To design and develop an automatic sprinkler system controlled by using programmable microcontroller PIC.
b To implement the automatic watering system based on soil moisture sensor. c To design and develop the prototype of the agricultural sprinkler system.
