it is not confined to any dedicated hardware Illustrations also include Arduino, Raspberry Pi, ESP8266, and a number of very well hardware modules Coding and uploading code to the board is made easier by the free and open-source Arduino Software (IDE) Any Arduino board may be used with this application All Hardwares of this IoT: Name Description The DHT11 module's humidity and temperature sensor will be designed to quantify the surrounding air's humidity and relay that information to the system With this, users may water plants remotely rather than physically, as the pump will so in response to their commands When the temperature detected by the sensor is hotter than the appropriate temperature, the fan will assist in reducing the ambient temperature since too high temperatures can harm the plants By using this sensor, the system will be able to determine the soil's state, which will allow us to determine when to water the plants By using this sensor, the system will be able to determine the soil's state, which will allow us to determine when to water the plants Based on the ESP8266 Wi-Fi Module, this Wireless Module CH340 Node MCU is an Internet of Things Module With just a few lines of Lua code, it is an open-source firmware and development kit that enables the prototyping of IoT devices With a server or client, it will manage a Wi-Fi connection An electronics prototyping platform is known as a breadboard or protoboard utilized to connect the wire to hardware The interconnection process is accompanied by the LCD's incredible number of legs, which also uses up a massive proportion of the microcontroller's legs An I2C converter module only needs two legs, as contrasted to the microcontroller's minimum need of six legs (RS, EN, D7, D6, D5, and D4) to connect to the LCD (SCL, SDA) Relays are electrically powered switches that may be turned on or off, enabling current to flow or not, and can be controlled by low voltages like the 3.3V provided by the ESP32 pin 3V3 Develop the solution Every one of the aforementioned hardware would be a part of the smart agricultural system and be accessible through WiFi Considering everything will be online, clients are able to test the functional requirement and performance on a smart device such as a computer, smartphone, tablet, or another smart device by running the Blynk app Via using hardware, the smart agricultural system will collect data about its environment and communicate it through the Internet to connected devices like smartphones and tablets by utilising the Blynk app The software will then process the data and transmit it to the client The air humidity, temperature, and soil moisture are the three variables that the software will provide In particular, that has three basic functions: it controls the light to check the temperature when it gets chilly; the pump to hydrate the plant when the soil moisture level is low, and the fan to adjust the air humidity when it becomes too high The system will notify via the Node MCU V3 CH340 - RF Kit ESP8266 whenever the moisture levels get too low and the notify is "plants need to be watered" Acknowledge receipt of the warning system, notifying the Blynk app in other smart devices that the soil moisture is lacking and indicating that the plant needs to be watered When the measure is adequate, the client can then restart the water and turn off the pump The air temperature and relative humidity warnings function similarly to the notification for soil moisture To warm the planet when it reaches the point and to cause the air humidity when it reaches over the acceptable limit, the user would need to switch on the fan Develop the air humidity sensor and automatic cooling fan My task in this project is to create and develop two of the primary functions which are air humidity sensing and an automatic cooling fan Similarly to another measure of Air Temperature and Humidity, I prefer the DHT11 Humidity Sensor to make the sensor Utilising a 5V Power relay to control and manage the Cooling fan 3010 The cooling fan will automatically start when the Humidity sensor determines that there is sufficient air humidity present on the farm Consequently, the land will be automatically irrigated The cooling fan shuts off when the air humidity becomes standard From anywhere in the globe, I may use Blynk Server to remotely observe everything that is happening Specific Hardware for these two functions: DHT11 Humidity Temperature Sensor: Although it's not too difficult to operate, data collection requires precise scheduling This sensor's sole significant drawback is that you can only collect new data from it once every two seconds As a result, sensor data used in the library may be up to two seconds outdated In this project, the atmospheric temperature and humidity will be measured using this sensor The other is a cooling fan Configuration of the hardware: Attach the DHT11 to pin D4 of the Nodemcu The cooling fan and relay are connected Using the NodeMCU's D7 Pin, I can control the relay The 5V pin of NodeMCU may be used to power the Cooling fan and Relay Only a 9V Supply Pin is needed for the Cooling fan, DHT11 Sensor and relay Figure 1: Configure hardware Figure 2: Configure hardware2 Source Code/Program The IoT Smart Agriculture & Automatic Irrigation System with ESP8266 Source Code is quite straightforward Direct uploading of the code to the NOdeMCU Board is possible Library: o ESP8266WiFi o BlynkSimpleEsp8266 I attach a variable to the pin D7's incoming value here in the code This is the fan's pin value, and if it equals 1, then implies the fan is being turned off via relay 1, in this example If not, we will switch on the fan Specifically, If the temperature, as well as air humidity, is greater than 30 and 15, the Cooling Fan will automatically start The data will be also printed on serial II RUN END-USER EXPERIMENTS THEN IDENTIFY THE PERFECT AND INCOMPLETE POINTS IN YOUR SYSTEM(P6) Deployment of all program The ESP8266WiFi.h and BlynkSimpleEsp8266.h libraries for the Node MCU V3 CH340-RF Kit ESP8266 and the DHT.h library for the Module temperature-humidity sensor DHT11 are included here, as well as all other essential libraries The next step is to define some of the system's implementation-related variables, such as the Wi-Fi accounts and certain hardware-related variables, including analogue Input = A0, Fan = D7, and Pump = D6 The only operation that takes place when a controller is reset is void setup() There is a setup code there from our team Install both hardware and software while setting up the entire system All of the code is repeatedly executed inside the void loop The author first used the Blynk run() method to launch the Blynk application After that, the author set two values for the temperature and air humidity in the variables h and t The technology will send a signal if the temperature increases greater than 30 degrees and the air humidity hits 85 per cent The soil moisture variable is then read from the analogue The system will issue a notification if the value is below 20 Design the Blynk app Our team will walk through each step of how to present the information on the user interface Begin by signing up for Blynk, then launch the Smart Agricultural system project After that, click on the screen, saunter down to the sidebar, and begin designing the interface The set-up of the app in this case is seen in the accompanying image Figure 3: Set up blynk This app will exhibit the temperature on the left and the air humidity on the right, accompanied by the soil moisture at the bottom position There will also be no buttons since all of these programs also automatic operate Our team will choose "Gauge" and change the name to "Air Humidity." Our team will set up the connection PIN for INPUT to be Virtual > V4 (0 100) with the label per cent Our team will pick Push in REFRESH INTERVAL and set the sensor reading speed to second Our team will enter "Temperature" as the name for the temperature display in the gauge configuration The connection PIN for INPUT will be set to Virtual > V5 (0 50) with the label being °C Our team will pick Push in REFRESH INTERVAL and set the sensor reading speed to second Go to Widget Box and choose Notification to see Messages displayed The author set the button here labelled "NOTIFY WHEN HARDWARE GOES OFFLINE" to OFF by default The author selects NORMAL as the default value in the "PRIORITY" section Test The Software Whenever the soil humidity and temperature meet the limit, data from the Blynk app will show up on the screen, telling you exactly whether or not the gadget is operational The pump and fans may be turned on or off by utilizing the Blynk's buttons whenever a warning is delivered Figure 4: Test Result The perfect and incomplete points in our system The Perfects: Supporting the progress of the solution, the system will have certain benefits and drawbacks The first value of the technology is that it helps clients to manipulate the environment with a precise number and monitor it remotely and over the Internet The system is intuitive nevertheless beneficial, enabling a list of advantages Incomplete Points: There are several incomplete points, including the probability of system damage without any warning to the user Whereas the system is an electrical machine, it requires a pump to fill the water, and if the pump blowouts, the water can deteriorate over time as a whole The proposes adding a way to check for the harmed system using the Blynk app as well as placing the pump in a secure location and using a high-quality pump to avert system damage throughout C TASK 2: EVALUATE YOUR IOT APPLICATION AND DETAIL THE PROBLEM YOUR IOT APPLICATION

sensor sometimes does not work However, this application is quite good at this price and it really easy to use 2 Evaluate the User Feedback At the first glance, my IoT product partly supports all the wishing of the customers on a Smart Agricultural could remotely use Based on feedback from users, this product is straightforward to use, and the price that I provide is also reasonable for any type of user Its performance is also quite good, it could detect the temperature, humidity, and soil moisture to notify whether it too high or low, auto cooling and watering the garden However, it still has some errors when working and the UI/UX in the mobile app is not good enough for some users The system must improve the temperature sensor so that users may utilize them based on reliable user feedback The system uses a wifi network to send data, therefore occasionally there may be issues with the internet that prevent the device from functioning correctly New hardware that works with the 5G network will be implemented in the upcoming edition Possibility of commercialization Currently, there are many farms or gardens in which the farmers or users still haven’t applied the IoT techniques such as Smart Agricultural System Hence, to help them extend and easy to manage the garden as well as the farm, the smart Agricultural System will be a solution for managing their plants Economic Feasibility A Smart Agricultural System will cost around 1,2 million VND to develop The current price per system for this IoT application is 1,8 million VND As a result, you will make 60 million VND if you sell this application to 100 individuals each month In the future, you may also develop and upgrade the application to increase its profitability IVI = 1,200,000 * 100 + 700,000 = 120,700,000 FVI = 1,800,000 * 100 – 1,400,000 = 178,600,000 ROI = (178,600,000 - 120,700,000) / (1,200,000 * 100) * 100 ROI = 48% Technical Feasibility In order to develop a plan and blueprint for how the Smart Agricultural System project is developed, maintained, transmitted, and tracked, the technological feasibility is applied For the project involving the smart lighting system, some elements of

is simple Organizational Feasibility II A project manager with at least years of experience will be in charge of the Smart Agricultural System project The developers must have 2-4 years of experience and be proficient in the programming language you have chosen The project manager will create the project's pattern and assist other developers in creating the highest-quality result Many individuals have tiny gardens at home, but they aren't always able to tend to them since they work outside In order to assist them in caring for their garden, they would require my Internet of Things program So, my Internet of Things application can be made profitable Future innovation will allow me to address a variety of additional needs, such as automated warming DISCUSS THE DRAWBACK OF YOUR SYSTEM AND SOLUTIONS FOR IMPROVEMENT Discuss the drawbacks: There are several drawbacks: The probability of system damage without any warning to the user Whereas the system is an electrical machine, it requires a pump to fill the water, and if the pump blowouts, the water can deteriorate over time as a whole The proposes adding a way to check for the harmed system using the Blynk app as well as placing the pump in a secure location and using a high-quality pump to avert system damage throughout Possibility For Improvement: The software can be expanded in the future to support customers' requirements after already being critically analyzed and through manual intervention; notwithstanding, the accuracy of the results nonetheless needs to be improved Additional components are added to examine the atmosphere, such as the wind and seeing pests or farm animals To guarantee privacy protection and maintain that system data is well-protected, the security needs to enhance tremendously When such temperature plummets, the machine will eventually switch on the heating light to warm the farms, which I would implement over the next development of this system In the future, I'll also implement a security feature to defend users' plantings It will have a camera because it has an automated detection mechanism for somebody sneaking into the farm So that it will become aware of the user and sound the alert to arouse suspicion of the outsider The UI/UX also will be improved in the future to make this more friendly for any type of user D CONCLUSION In the final point, I have discussed a variety of topics related to the technology of our IoT System, Also with a critical perception of a product, I also included user feedback and comments In order to accommodate evolutionary biology, it is
