PROBLEM STATEMENT the people. Therefore, farmers use a variety of technologies for better yields and to reduced human intervention. Fast the development of human civilization and the development of new science and technologies change the state of health in the world, leading to significant changes in the environment. In India, population growth of about 2% per year. It is important that food production increases about 2.5% per annum to provide better food. Water resources must be used effectively and efficiently. This technique prevents over and under irrigation. Irrigation plays a vital role in the growth of plants. This automated irrigation system is proposed to provide an optimum amount of water for the growth of crops and to sense the moisture content present in the soil. The proposed system is designed with suitable sensors, signal conditioning circuits, camera module, microcontroller circuit and integrated with IoT environment to achieve automation in agriculture which is the necessity of farmers. It also prevents manual switching on and off of motor pumps. The proposed system helps in managing water efficiently by providing water in required cultivation. The system can also be implemented in small gardens in homes and parks, other than agricultural fields.
It becomes a challenge for farmers to keep their plants healthy and viable. Also it is hard to maintain a field with proper moisture content during insufficient supply of water. Considering this situation, it is necessary to implement an automated irrigation system which will take care of larger fields as well as in-house gardens. This technology not only helps in increasing the productivity of crops but also updates the user with status of the plant. Therefore, it is a simple technique that provides a solution for watering a potted plant or crop with reduced human supervision.
3. PROPOSED SYSTEM In this proposed system, soil moisture sensors are copper strands which are inserted into the ground. Soil sensitivity arrangement measures soil movement. Wet soil will be more efficient than dry soil. The soil sensor editing module has a comparison in it. The voltage from the prongs and the predefined voltage are comparable and the output of the printer is high only when the ground condition is dry. This output from the ground sensor system is provided with an analog input pencil for the small controller. The microcontroller always monitors the analogue input pin. When the moisture in the soil is above the limit, the small controller displays a message that means the same and the motor is turned off. When the effect from the soil sensing system is high i.e. the soil moisture decreases. This will activate the small controller and display the appropriate message on the LCD. When the transistor is turned on, the relay coil becomes active and turns on the motor. When the soil moisture reaches a threshold value, the output of the soil sensor output is low and the motor is switched off.

1. INTRODUCTION Irrigation is the process of supplying water to the crops artificially to fulfil water requirements for crops. Nutrients and other supplements are provided to the crops by irrigation. In any irrigation system, the prime motive will be to use the water efficiently so that over and under irrigation can be avoided. The manual switching on and off reduces human intervention so that overall cost can also be controlled. By using this technique, we can monitor the field from desired places
4. TECHNICAL BACKGROUND 4.1 HARDWARE DESCRIPTION
1.1 OBJECTIVE
The moisture sensor is interfaced with PIC microcontroller. The input signals of the moisture sensor are sent to the PIC microcontroller. Whenever the moisture content of the soil drops, the sensor senses the change, giving signal to the microcontroller so that the pump will be activated. The microcontroller continuously monitors the analogue input pin. When the moisture present in the soil is above the given threshold value, the microcontroller automatically displays an appropriate message. It will trigger the microcontroller
The main objective of automated irrigation system is to minimize the wastage water and also to reduce the cost required for manpower. Since it is an automated technique it will be more efficient compared to other manual methods. The proposed system will provide an ideal amount of water required to maintain the moisture content present in the soil. Thus optimum amount of water will be supplied to the crops. The process of monitoring the crops will become more easy.
