   1. INTRODUCTION

      The next era of Smart Computing will be based on the Internet of Things (IoT). The Internet of Things (IoT), these days is playing a crucial role in transforming Traditional Technology'' from homes to offices to Next Generation Everywhere Computing. One of the main areas where IoT based research is going on and new products are launching on an everyday basis to make the activities smarter and efficient towards better production is in the field of Agriculture. Agriculture sector is regarded as the most crucial sector globally for ensuring food security. Speaking of India farmers, they are right now in huge trouble, a disadvantageous position in farm size, technology, trade, government policies, climate conditions etc. Agricultural production requires lots of activities like soil and plant monitoring, environmental monitoring like moisture and temperature, transportation, supply chain management, infrastructure management, control systems

      management, animal monitoring, pest control etc. Monitoring the environmental factors is not the complete solution to increase the yield of crops. There are a number of other factors that decrease productivity to a greater extent.

      Hence, automation must be implemented in agriculture to overcome these problems. So, in order to provide a solution to all such problems, it is necessary to develop an integrated system which will take care of all factors affecting the productivity in every stage. But complete automation in agriculture is not achieved due to various issues. Though it is implemented in the research level and it is not given to the farmers as a product to get benefited from the resources. Hence this paper deals about developing smart agriculture using IoT Devices which can be used by farmers.

      In India, the projected population by 2050 is considered as approx. 1500 million and agriculture remaining their primary source of living in rural areas, the focus should be on the increase of agricultural productivity. Though our country claims that they have developed in the field of science and technology, erratic power supply or complete breakdown of electricity for many hours together has almost become routine today. Use of Solar power is increasing today worldwide as a renewable source of energy. India has huge untapped solar off-grid opportunities. The main advantage of this project is optimizing the power usage through water resource management and also saving the government's free subsidiary electricity. This proves an efficient and economic way of irrigation and this will help in automating the agriculture sector.

   3. PROPOSED SYSTEM

      1. BASIC BLOCK DIAGRAM:

         In fig. 1 block diagra of the system is shown. It uses a raspberry pi 2. The sd card for storing the notices is connected to the raspberry pi. The raspberry is connected to the wifi using ethernet. Hdmi acts as the interface between the lcd and the raspberry pi.

         Fig. 1. block diagram of the proposed system

      2. BLOCK WISE WORKING:

         When the power supply is switched on, the GSM modem gets initialized. The GSM modem communicates with the ARM LPC2148 board using AT commands. The LCD display is connected to the ADC pins of the ARM processor, in order to display the message. The humidity sensor checks for the soil moisture content whose maximum threshold is kept at 1000oc and minimum of 300oc. When the soil moisture content is less than 300oc the pump motor will pump the water to the filed. The temperature sensor will measure the surrounding temperature of the farm. The rain sensor will sense the heavy rain and closes the panel to protect the crop. All the above information will be informed to the user using GSM technology.

      3. HARDWARE COMPONENTS:

         The hardware components which will perform all these functions are:

         1. NODE MCU CHIP:

            NodeMCU is a low-cost open source IoT platform. It initially included firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which was based on the ESP-12 module. Later, support for the ESP32 32-bit MCU was added. The prototyping hardware typically used is a circuit board functioning as a dual in-line package (DIP)

            which integrates a USB controller with a smaller surface-mounted board containing the MCU and antenna. The design was initially was based on the ESP-12 module of the ESP8266, which is a Wi-Fi SoC integrated with a Tensilica Xtensa LX106 core, widely used in IoT applications

            Fig. 2. NODE MCE chip

         2. GSM MODULE:

            GSM Modem can accept any GSM network operator SIM and it can act just like a mobile phone with its own unique phone number. The necessity to use this is it can use RS-232 protocol which can be easily connected to the controller. It can be used like a phone where it can send and receive SMS and make a call. The GSM modem is connected to the controller through RS232. The SMS is sent through the terminal to the number using AT Commands.The security strategies standardized for the GSM system make it the most secure telecommunications standard currently accessible. Although the confidentiality of a call and secrecy of the GSM subscriber is just ensured on the radio channel, this is a major step in achieving end- to- end security.

            fig. 3. GSM Module

         3. SOIL MOISTURE SENSOR:

            Soil moisture sensor is a sensor which senses the moisture content of the soil. The sensor has both the analog and the digital output. The digital output is fixed and the analog output threshold can be varied. It works on the principle of open and short circuit. The output is high or low indicated by the LED. When the soil is dry, the current will not pass through it and so it will act as an open circuit. Hence the output is said to be maximum. When the soil is

            wet, the current will pass from one terminal to the other and the circuit is said to be short and the output will be zero.

            Fig. 3. Soil Moisture Sensor

         4. TEMPERATURE SENSOR:

            The LM 35 sensor is highly used because its output voltage is linear with the Celsius scaling of temperature. It does not provide any external trimming. It has a wide operating range. The maximum output is 5V. It consumes a minimum amount of electricity. Thus, it is energy efficient. It is very efficient in horticulture. It is user friendly to use. The most common type of temperature sensor is a thermometer, which is used to measure temperature of solids, liquids and gases. It is also a common type of temperature sensor mostly used for non- scientific purposes because it is not so accurate. Temperature sensors are used in many applications like HVand AC system environmental controls, food processing units, etc.

            Fig. 4. Temperature Sensor

         5. PIR SENSOR:

            All objects with a temperature above absolute zero emit heat energy in the form of radiation. It is invisible to the human eye since it radiates infrared wavelengths. PIR sensors dont detect or measure heat, instead they detect the infrared radiation emitted or reflected from an object. It is used to detect the movement of people, animals or other objects. When a human passes in the field, the temperature at that point will rise from

            room temperature. The sensor converts the resulting change into a change in the output voltage and this triggers the detection.

            Fig. 5. PIR Sensor

         6. LIGHT SENSOR:

            A light dependent resistor also known as a photoresistor or photoconductor or photocell, is a resistor whose resistance depends on light intensity. LDRs are light sensitive devices. The light sensor is a passive device that converts this light energy whether visible or in the infra-red parts of the spectrum into an electrical signal output. Light sensors are more commonly known as Photoelectric Devices or Photo Sensors'' because they convert light energy (photons) into electricity (electrons). Photoelectric devices can be grouped into two main categories, those which generate electricity when illuminated, such as Photo-voltaics or Photo-emissives etc, and those which change their electrical properties in some way such as Photo-resistors or Photo-conductors. This leads to the following classification of devices.

            Fig. 6. Light Sensor

         7. Wi-Fi MODULE:

         The ESP8266 Wi-Fi Module is an independent system on chip with built-in TCP/IP protocol stack which allows the microcontroller to access the Wi-Fi network. The ESP8266 has the potential of either hosting an application or discharging the Wi-Fi networking functions entirely from an additional application processor. This module has a powerful enough on-board processing and storage capability that allows it to be integrated with the

         sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime.

         Fig. 7. Wi-Fi Module

      4. SOFTWARE USED:

      Arduino IDE is an open-source software program that allows users to write and upload code within a real-time work environment and upload it to the board. As this code will thereafter be stored within the cloud, it is often utilised by those who have been searching for an extra level of redundancy.The Environment is written in Java and based on Processing and other open-source software . The system is fully compatible with any Arduino software board.

   4. METHODOLOGY

      In the Recent era of IoT, many new research has been conducted in terms of Smart IoT based products development which will help farmers in Smart Farming in terms of Managing Crop, Pest Control, Agriculture Precision, Agriculture Fields Monitoring through different Sensors and even Drones. In this part, Smart IoT based Agricultural stick is being developed for live monitoring of Temperature, Moisture using Arduino and various other electrical components. The temperature sensor senses the surrounding temperature of the farm in different farm conditions. When raining is observed by the sensor, the pump motor will stop pumping the water to the field and updates the user using GSM/GPRS technique. When there is an unconditional rain the panels provided will be closed automatically to protect the crop. An Alphanumeric LCD is used to display the data.
