Watering systems ease the burden of getting water to plants when they need it. Knowing when and how much to water is two important aspects of watering process. To make the gardener works easily, the automatic plant watering system is created. There have a various type using automatic watering system that are by using sprinkler system, tube, nozzles and other. This system uses Arduino UNO board, which consists of ATmega328 microcontroller. It is programmed in such a way that it will sense the moisture level of the plants and supply the water if required. This type of system is often used for general plant care, as part of caring for small and large gardens. Normally, the plants need to be watered twice daily, morning and evening. So, the microcontroller has to be coded to water the plants in the greenhouse about two times per day. However for most people it becomes challenging to keep them healthy and alive. This system automation is designed to be assistive for the University Park. This system hopes that through this prototype people will enjoy having plants without the challenges related to absent or forgetfulness.


INTRODUCTION
Arduino is an open-source electronics electronic platform based on easy-to-use hardware and software. Arduino boards are able to read inputs-light of sensor, a finger on a button, or a Twitter messages,-and turn it into an outputactivating on a motor, turning on an LED, publishing something online. Over the years Arduino has been the brain of thousands of projects, from everyday objects to complex scientific instruments. A worldwide community of markers has gathered around this open-source platform, their contributions have add to up an incredible amount of accessible knowledge that can be of great help to novices and experts alike.
Arduino was born at the Lvrea Interaction Design Institute as an easy tool for fast prototyping, aimed at students without a background in electronics and programming. As soon as it reached a wider community, the Arduino board started changing to adapt to new needs and challenges, differentiating its offer from simple 8-bit boards to products for IoT application, wearable, 3D printing, and embedded environments. All arduino boards are completely opensource, empowering users to build them independently and eventually adapt them to their particular needs. The software too, is open-source, and it is growing through the contributions of users worldwide. There are two functional components in this system. They are the moisture sensors and the motor/water pump. Thus the Arduino Board is programmed using the Arduino IDE software. The function of the moisture sensor is to sense the level of moisture in the soil. The motor/water pump supplies water to the plants.

SYSTEM REQUIREMENTS
The description of hardware and software components required in the design and implementation are as follow: This is an Arduino UNO board. Before using it, the program can be compiled from the computer or laptop. After compiling the program, it is ready to use. 4.2 The process of making system Step1: Firstly, Arduino UNO board, relay module, power supply and moisture sensor are setup on the board. These processes are shown in figure; Step2: And then relay and Arduino UNO board are connected in all pins, Step3: Moisture sensor is also connected to the UNO board to sense the water content of the plant. This process is shown in figure; Step4: In this step, the motor is connected to the relay. This is as follows;

Write the program using Arduino IDE
The user have had the Arduino IDE software to write the program.
Arduino UNO board is connected to the computer using the USB cable. And then, double-click the Arduino application, and then write the program.  If the users selected the serial port, the users can write the coding for the process. Now, simply click the "Upload" button in the environment. Wait a few seconds -the users should see the RX and TX leds on the board flashing. If the upload is successful, the message "Done uploading." will appear in the status bar.  digitalWrite(13,HIGH); } delay(400); } 6. CONCLUSION Although it seems to be more demanding and challenging, there are many other possibilities like creating complex connections of plants of similar variety or so-called "Internet of Plants". Also, using more than one sensor is another idea for an experimental venture, but there are also many other experimental and challenge-like ideas such as using solar power supply, timer for setting irrigation system etc. However, independently of the way used to construct it, there is no doubt that this system can be very helpful in solving many problems, from those that seem harmless to those that are on the scale of the most important and most dangerous ones for human population. By means of this system, it is possible to control the amount of water released from the process of watering the plant. This system automation is designed to be assistive for the University Park. Although it can be very helpful for humanity in general, agriculturists, craftsmen, and botanists could have the biggest benefit of using this system.
