INTRODUCTION TO SMART AGRICULTUREAs the world is slanting into new advancements and usage it is an essential objective to drift up in agribusiness moreover. Many researches are done in the field of agriculture. Most undertaking projects con note the utilization of wireless sensor network collect data from different sensors deployed at various nodes and send it through the wireless protocol. The gathered information gives the data about the different various environmental factors. Monitoring the environmental factors isn’t the total answer for increment the yield of products. There are number of other factors that decline the efficiency to a more prominent degree. Thus computerization must be executed in farming to defeat these issues. So, in order to provide 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 farming isn’t accomplished because of different issues. Despite the fact that it is actualized in the research level it is not given to the farmers as a product to get benefited from the resources. Thus this paper bargains about creating developing smart agriculture using IoT and given to the farmers. II. LITERATURE SURVEY The traditional method and one of the oldest ways in agriculture is the manual method of checking the parameters. In this methodology the farmers they themselves check each and every parameter and calculate the readings. It not only focuses on developing devices but also on tools to manage, displays and alerts the users using the advantages of a wireless sensor network system. Its objective is to make agriculture smart using automation and IoT technologies. The featuring highlights are smart GPS based remote controlled robot to execute undertakings like weeding, spraying, moisture sensing, human detection and keeping vigilance.The cloud computing devices that can develop a complete computing system from sensors to tools that monitor data from agricultural field images and from human actors on the ground and precisely feed the data into the repositories along with the location as GPS coordinates. This thought proposes a novel procedure for smart farming by linking a smart sensing system and smart irrigator system through wireless communication technology. It not only proposes a low cost but also efficient wireless sensor network technique to acquire the soil moisture and temperature from various location of farm and as per the need of crop controller to take the decision whether the irrigation is enabled or not. It proposes a novel thought regarding how automated irrigationsystem was implemented to optimize water utilization for agricultural crops. In addition, a gateway unit handles sensor information. The environmental conditions are observed and controlled online by using Ethernet IEEE 802.3.The partial root zone drying process can be implemented to a maximum extent. It is intended for IoT based monitoring system to examine crop environment and the way to improve the efficiency of decision making by analyzing harvest statistics. In this paper image processing is utilized as an instrument to observe the diseases on fruits during farming, right from plantation to harvesting. The variations are seen in color, texture and morphology. In this paper, greenhouse is a building in which plants are grown in closed environment. It is used to maintain the optimal conditions of the environment, greenhouse management and data acquisition. III. PROPOSED WORK In the field section, different sensors are implemented in the field like temperature sensor, moisture sensor and PIR sensor. The data gathered from these sensors are connected to the micro-controller through RS232. In control section, the received data is verified with the threshold values. If the data surpasses the threshold value the alarm is switched ON and the LED starts to blink. This alarm is sent as a message to the farmer and automatically the power is switched OFF after sensing. The values are produced in the web page and the farmer gets the detailed description of the values. In manual mode, the user has to switch ON and OFF the micro-controller by pressing the button in the Android Application developed. This is done with the help of GSM Module. In automatic mode, the micro-controller gets switched ON and OFF automatically if the value exceeds the threshold point. Soon after the micro-controller is started, automatically an alert must be sent to the user. This is achieved by sending a message to the user through the GSM module. Different parameters such as the temperature, humidity, moisture and the PIR sensors shows the threshold value and the water level sensor is used just to showcase the level of water inside a tank or the water resource.

The sensor has both theanalog and the digital output. The digital output isfixed and the analog output threshold can be varied.It works on the principle of open and short circuit.The output is high or low pointed out by the LED.When the soil is dry, the current will not passthrough it and thus it will act as open circuit. Hencethe output is said to be maximum. When the soil iswet, the current will pass from one terminal to theother and the circuit is said to be short and theoutput will be zero. The sensor is platinum coated tomake the efficiency high. The range of sensing is alsohigh. It is anti-rust and so the sensor has long lifewhich will afford the farmer at a minimum cost.TEMPERATURE SENSORFig 4.4: Temperature SensorThe LM 35 sensor is highly used because its outputvoltage is linear with the Celsius scaling oftemperature. It does not provide any externaltrimming. It has a wide operating range. Themaximum output is 5V. The output will increase10mV for every one degree rise in temperature. Therange is from -55 degrees to +150 degrees. There arethree terminals as Vcc, Ground and the analogsensor. It consumes minimum amount of electricity.Thus, it is energy efficient. It is very efficient inhorticulture. It is user friendly to use.PIR SENSORAll living and non-living things with a temperatureabove absolute zero emit heat energy in the form ofradiation. It is invisible to the human eye since itradiates infrared wavelengths. PIR sensors don’tdetect or measure heat, instead they detect theinfrared radiation emitted or reflected from anobject. It is used to identify the movement ofpeople, animals or other objects. They arecommonly used in burglar alarms and automaticallyactivated lighting systems. When a human passes inthe field, the temperature at that point will rise fromroom temperature.Fig 4.5: PIR SensorThe sensor converts the resulting change into achange in the output voltage and this triggers thedetection.V.
