Smart irrigation system pdf

The benefit of employing these techniques is to decrease human interference and it is quite feasible and affordable.

This Smart irrigation system project is using an arduino micro-controller, that is programmed to collect the input signal according to moisture content of the soil and its output is given to the op-amp that will operate the pump. Agriculture also has a major impact on economy of the country. The consumption of water increases day by day that may leads to the problem of water scarcity.

Now a days, farmer are struggling hard in the agriculture field and the task of irrigating field is becoming quite difficult for the farmers due to lack of regularity in their work and negligence because sometimes they switch on the motor and then forget to switch off which may leads to wastage of water.

Similarly, they even forget to switch ON the irrigation system, which again leads to damage to the crops. To overcome this problem, we have implemented a new technique by using Arduino microcontroller. In this project we are using soil moisture sensor which is used to sensing moisture level whether the soil is dry or wet. The moisture sensor is interface with arduino microcontroller that will work by the process of simulating on PROTEUS software and based on that it activate the DC motor through op-amp which compare the level of moisture content of the soil with the reference value that will operate the pump through relay..

Water is a very precious resource and must be properly utilized. Agriculture is one of those areas which consume a lot of water. Irrigation is a time consuming process and must be done on a timely basis. The aim of the article is to develop an smart irrigation system which measures the moisture of the soil and automatically turns on or off the water supply system. The effects of the applied amount of irrigation water, irrigation frequency and water use are particularly important. To improve water efficiency there must be a proper irrigation scheduling strategy.

So our project devices a simple system, using a arduino microcontroller to automate the irrigation and watering of crops with minimal manual interventions. Since, the water is irrigated directly in the land, plants under go high stress from variation in soil moisture, therefore plant appearance is reduced. The absence of automatic controlling of the system result in improper water control system. The major reason for these limitations is the growth of population which is increasing at a faster rate.

At present there is emerging global water crisis where managing scarcity of water has become a serious job. This growth can be seen in countries which have shortage of water resources and are economically poor.

So this is the serious problem in All rights reserved by www. This prototype monitors the amount of soil moisture content in soil. A predefined value of soil moisture is set and can be varied with crops.

In case of dry soil, it will activate the irrigation system, pumping water for watering the plants. In simulation, pin2 and pin3 are used as a input pin for DC motor and switch respectively. This system can be implemented on a large scale for farming purposes, which can further prove to be more advantageous. Owing to prevailing conditions and water shortages, the optimum irrigation schedules should be determined especially in farms to conserve water. In simulation process we are using four components namely Arduino microcontroller, Simple DC motor, Switch, Standard resistor of 10 kilo ohm.

Three components are interface with Arduino microcontroller in such a way that DC motor connected at pin2 and switch and resistor connected at pin3. All these are connected as an input pin. Sensing arrangentment is made by inserting two stiff metallic rods into the field at some distance. An op-amp is used as a comparator that interfaces microcontroller and the sensing arrangement.

On receving the signal, the microcontroller produces an output that the drive a relay and operates the water pump. Raspberry Pi acts as minicomputer. It is having own III. Temperature and soil A. Breakdown Structure Modules moisture sensor connected to raspberry pi and they send signal to raspberry pi. Sensor values are compared with threshold value given or set by user. Sensors: a Soil moisture sensor: The soil moisture sensor is used to measure the volumetric water content of soil.

It is used to monitor soil moisture content to control irrigation in greenhouse. A moisture sensor is used to sense the level of moisture content present in irrigation field.

It has a level detection module in which we can set a reference value. System Configuration: The temperature sensors are necessary to reduce the System configuration module is used to configure watering times when the weather gets cooler and less all the hardware devices.

Soil moisture sensor, water is needed. Then as the weather begins to warm up, Temperature sensor, Wi-Fi module all are to add more watering time. Android App: pi , initially we required to install Raspbian operating system on raspberry pi and related gpio Client will be android based application and this connection with soil moisture sensor, Temperature module will be responsible to take inputs from user.

Raspberry pi input will 2. Send Notification: Once the values of sensors are to farmers. Algorithm V. When sensor values condition is satisfied then V. V, Maneesha V. Aware Wireless Irrigation System".

And if mode is manual then system turns Volume 4, Number 4 , pp. Control hardware. This paper is based on Android and raspberry pi platform both of which are Free Open Source Software.

So the overall implementation cost is cheap and it is an orderable by a common person.
