BACKGROUND OF THE PRESENT INVENTION
Agriculture is a source of livelihood of majority pf people and has great impact on the economy of the country. Efficient water management is a major concern for many cropping systems In dry areas or in case of inadequate rainfall irrigation becomes difficult. So, it needs to be automated for proper yield and safe of water. This multi-sensor system will continuously monitor the relevant environmental parameters, hydrological parameters, soil parameters and crop specific parameters to derive the context. These derived contexts will be used for automatic control and adaptation of the irrigation system. This system uses the real-time sensor data to minimize the wastage of water used in the irrigation process. Applying the internet of things to the highly effective and safe agricultural production has a significant impact on ensuring the efficient use of water resources as well as ensuring the efficiency and stability of the agricultural production. The temperature, humidity and moisture values are obtained from the respective sensors. Motion is detected by using PIR sensor in order to prevent the tampering of device on the field. By using the obtained values, the motor is controlled. The output variables are also loaded into a cloud called as Dweet . The values from the cloud is retrieved and displayed at the user device by using an Online Dashboard. The DHT11 sensor detects the temperature and humidity and sends it to the microcontroller. The soil moisture change is detected based on the water content on the soil and the PIR sensor detects the motion. The user can check the status of the field

anytime by using a smartphone in which all the parameters are displayed. This helps the user to easily analyze the field automatically by using the internet. The user can also switch ON/OFF the motor by using his smartphone or computer.

The central control system is configured to derive and send an irrigation schedule for the irrigation site. The smart scheduler comprises a data receiver, a processor, and a signal interface. The data receiver is configured to receive the irrigation schedule. The processor is configured to convert the irrigation schedule to a series of control signals that the irrigation controller recognizes. The signal interface is configured to connect to the irrigation controller and to send the series of control signals to the irrigation controller. The system uses weather data and irrigation site-specific information to automatically apply the optimal irrigation schedule. Users are able to remotely control the irrigation via networks such as Internet.
SUMMARY OF THE INVENTION
The device is designed using a CC3200 launchpad. It has an ARM Cortex- M4 at 80 Mhz and an inbuilt Wifi. It comprises of a DHT11 temperature and humidity sensor, YL-69 moisture sensor and a PIR sensor to detect the respective parameters from the applied environment. It also has a L293D motor driver to control the motor. A 12v Dc motor is used and it is controlled by using the obtained parameters from the sensor. The mechanism involves a combination of Fuzzy logic and loT which needs no manual intervention. It is also powered by a solar battery.
THE OVERALL ASSEMBLY WORKS AS FOLLOWS
This system uses a CC3200 launchpad which has an inbuilt WiFi which helps it to easily connect itself to the internet. The temperature, humidity and moisture values are obtained from the respective sensors(Fig 1,2). Motion is detected by using PIR sensor in order to prevent the tampering of device on

the field. By using the obtained values, the motor is controlled. The output variables are also loaded into a cloud called as Dweet. The values from the cloud is retrieved and displayed at the user device by using an Online Dashboard. The sensors are interfaced with the CC3200 launchpad along with the motor by using a L293D motor driver(Fig 9). The system automatically detects all the parameters like temperature, humidity, motion and moisture and sends it to the cloud by using the onboard WiFi. The values of these parameters can be visualized by the user in his smartphone or computer. A fuzzy level is also set so that the motor is controlled automatically without any manual operation. It makes use of a solar battery(Fig 2 ) to power the microcontroller. This helps in saving a lot of energy, water and it does not need any continuous monitoring. The user can also switch On/Off the motor by using his mobile or PC(FiglO).

DESCRIPTION OF THE DISCLOSED EMBODIMENT

The device is designed using a CC3200 launchpad. It has an Arm cortex- M4 at 80 Mhz and an inbuilt Wifi. This launchpad requires a voltage of 3.3v which is less than many commonly used MCUs, thereby reducing the power consumption needed for irrigation. . It consists of a DHT11 temperature and humidity sensor, YL-69 moisture sensor and a PIR sensor. These sensors are used to detect the respective parameters from the applied environment. The system automatically detects all the parameters like temperature, humidity, motion and moisture and sends it to the cloud by using the onboard Wifi. The
