GovindaraajanDepartment of Information TechnologySri Sairam Engineering CollegeChennai-600044, India ABSTRACT This paper proposes the smart IOT (Internet ofThings) in Gardening. This project provides the smart way of monitoring themoisture content in the soil and humidity in the air. When the moisture contentis low or the humidity is low it is sensed by the dh11 sensor which is fixed inthe garden. This sensor is then connected to the WeMos D1 R2 mini called amicro controller and it is further connected to the motor pump. The micro controller controls the motor pumpwith the help of motor driver. If themoisture content reduces, the drip irrigation system takes place with the helpof solar powered motor pump.
The value of humidity and moisture is beenmonitored with the help of micro controller. The values of humidity and moisture is stored in thefirebase with the help of micro controller. The firebase is connected with themobile app to transmit the data. So that we can monitor the moisture contentand the humidity level required for the plant and effective utilization ofwater and man power for the proper growth or yield. INTRODUCTION– Internet Of ThingsIntroductionto Internet of Things (IOT): TheInternet of Things (IOT) is the network of physical devices, vehicles, homeappliances and other items embedded with electronics, software, sensors,actuators and network connectivity. The IOT allows objects to be sensed orcontrolled remotely across existing Network Infrastructure, creatingopportunities for more direct integration of physical world into computer basedsystem and resulting in improved efficiency, accuracy and economic benefit inaddition to reduce human intervention.
“Things” in IOT refers to widevariety of devices such as heart monitoring implants, biochip transponders onfarm animals, automobiles with built in sensors and DNA Analysis devices etc.Internet of Things represents a general concept for the ability of networkdevices to sense and collect data from the world around us and then share thedata across the internet and it can be processed and utilized for variousinteresting purposes. WORKING: Thisproject aims at helping the farmers in agricultural field by using IOT(Internet of Things). It provides the smart way of monitoring themoisture content in the soil and humidity in the air. When the moisture contentis low or the humidity is low during summer it is sensed by the DHT11 sensorwhich is fixed in the garden.
DHT11 sensor is a humidity and moisture Sensor,which generates calibrated digital output. DHT11 can be interface with WeMosD1 R2 and get instantaneous results.This sensor is then connected to the WeMos D1 R2 mini called a micro controller.The WeMosD1 R2 is used in processing all the vital programming functions and consider theprogram as commands for the other electrical connectivity. The microcontroller controls the motor pump with the help of motor controller. A Motor Controller is a device that acts as intermediarybetween WeMos D1R2 micro controller and motor.If the moisture content reduces, the dripirrigation system takes place with the help of solar powered motor pump.
Thevalue of humidity and moisture is been monitored with the help of microcontroller .The values of the humidity and moisture is stored in the firebasewith the help of micro controller. Firebase is a mobile and web application developmentplatform, connected to the mobile app with the help of micro controller WeMosD1R2 which transmits the data to the user.
The mobile app is been made with thehelp of MIT app inventor.RELATEDWORKSPlant watering automation:The plants are watered twice a day by eithersprinklers or dripper with ATmega328 microcontroller programmed to sensemoisture level of plants at particular instance of time, if the moisturecontent is less than specified threshold which is predefined according toparticular plant’s water need then desired amount of water is supplied till itreaches threshold. Smart Agriculture: Helps to reduce wastage, effective usage offertilizer and thereby increase the crop yield.
In this work, a system isdeveloped to monitor crop-field using sensors (soil moisture, temperature, humidity,Light) and automate the irrigation system. The data from sensors are sent toWeb server database using wireless transmission. In server database the dataare encoded in JSON format. The irrigation is automated if the moisture andtemperature of the field falls below the brink.
In greenhouses light intensitycontrol can also be automated in addition to irrigation. The notifications aresent to farmers’ mobile periodically. The farmers’ can able to monitor thefield conditions from anywhere FUTUREENHANCEMENTS This Garden automation has a very good scopein the near future. It helps to reduce the cost and can be done with usingminimal resources at reduced cost. It also aims at reducing the wastage ofwater usage. The project mainly aims at the automation of public garden toavoid wastage of resources. This can be expanded in the sense of security usingmetal detectors and CCTV footages.
Also using GSM the Garden automation can becontrolled using mobile applications.This project can be extended to a wide level byconnecting a large number of sensors to a microprocessor which can performmultitasking like Raspberry pi 3 through ZigBee transmitters and receivers andcan improve our farming methods further by implementing various ideas of IOT inAgricultureThe temperature and humidity sensors capturethe data and send it to the centralized cloud servers where it gets processed.The farmers can get all the details about their farm and also they can interactwith the drip through their mobile devices. With the project being developedwith the latest technologies, new sensors can be added which can add chemicals,Fertilizers to the required amount. The smart drip irrigation system can beused in commercial as well as agricultural use.CONCLUSION Thus the project is expected toachieve some of the important goals such as 1) Low installation cost: The assembly ofthe system must be in expensive. A domestic user must be able to afford this touse for their home plants.2) Reduced labour: Once the system isinstalled, there will be no labour required for refilling the water as this isaimed to be the first aspect of full automation.
3) Reduced Monitoring: Requirement of humansurveillance is not needed for the entire day but once a day just to make surethe system works perfectly normal. This is the second aspect of fullautomation.4) Decrease in water consumption: Since itis being controlled automatically, usage of water is restricted to the requiredlevel and it is third aspect of full automation.5) Low maintenance: A good system requiresonly a small maintenance level. In such case our system parts should never failfor the first five years also the body parts should be available easily. 6) Low power consumption: The consumptionof electrical energy should also be minimized to reduce the total costassociated with the system. This can be achieved if the system is used widelyin large scale. Bythe time the world runs through technology, all the electronic componentsrequired for this project can be brought and integrated into a single chip.
