Project 1
Due Date: 30/07/2022 (23:59 PM)
Basic Directions:
• This can be a group task with FOUR members in a crew.
• Solely digital submissions can be accepted. Your resolution must be submitted by way of the ipearl emasters platform.
• Just one particular person from the group ought to submit the task.
Question Assignment 1 (100 Marks)
Aravind is an formidable farmer who desires to enhance the yields from his farmland. Whereas searching for methods to enhance the yields, he got here throughout tech buzzword just like the Web of Issues. The irrigation system he desires to construct comprises servo motors that management the water provide to the farm, primarily based on the current humidity, temperature ranges within the farm.
The irrigation system he desires to construct comprises servo motors that management the water provide to the farm, primarily based on the current humidity, temperature ranges within the farm. Utilizing sensor information, Aravind desires to construct a sensible irrigation system that predicts how a lot water (in proportion) needs to be equipped to his farm. Aravind additionally doesn’t need to water the vegetation throughout night-time.
Nonetheless, Aravind is nice at farming and doesn’t have a lot expertise constructing an IoT system. So, construct an irrigation system for Aravind utilizing the IoT simulator at this hyperlink (https://wokwi.com/tasks/new/arduino-mega?template=arduino-mega) and design a farm irrigation circuit utilizing Arduino Mega board. Establish the required sensors wanted to construct the irrigation system primarily based on Aravind’s necessities from the listing of sensors supplied by the simulator. The irrigation system ought to produce the proper sign (% of water provide) to regulate the water provide relying on the temperature and humidity values. Use a servo motor to regulate the water provide.
The farm irrigation system ought to include 4 sensor models such that every unit sense temperature and humidity values. These values can be supplied to rule-based mannequin as proven in Desk 1 on the Arduino board to foretell the water movement in proportion. Then the water movement proportion can be supplied as enter to the servo motor (Map the proportion values with servo motor rotation zero? to 180?). The sensor values from every sensor unit ought to management a servo motor. Additionally, show the % of water movement that’s fed as enter to servo motors on an LCD (Discuss with Determine. 1). The block diagram for the circuit schematic is proven in Determine 2.
Temperature (C) Humidity (%) Water movement prediction (%)
Low ( 25) Low (40) 100%
Low ( 40) Low ( 65) 60%
Medium (25-35) Medium (40 -70) 40%
Excessive ( 35) Excessive ( 70) zero%
Desk 1. Guidelines for water provide prediction
Determine 2: Block Diagram of Irrigation System
Deliverables:
1. Submit a report in pdf format mentioning how you’ve gotten constructed the irrigation system, the sensors used. Additionally, present the hyperlink to your simulated undertaking within the report (You may generate the hyperlink in your undertaking from the simulator by signing in and saving the undertaking).
2. The answer for the task needs to be submitted as a zipper file. The file needs to be named as Member1RollNumber Member2RollNumber.zip.
three. Downloaded zip file of the simulation from the simulator (It ought to include sketch.ino and diagram.json information).
Anticipated performance out of your simulation:
• The sensors current within the simulator include slider bars to regulate the sensor readings. When adjusting the sensor inputs (Temperature, Humidity, Day/Night time), the rule-based mannequin ought to predict the suitable water movement in proportion. Your simulation ought to print the expected water movement % on LCD display screen and management the servo motor proportional to the water movement %.
• When explicit sensor values are modified, solely the servo motor that makes use of information from that sensor ought to change its state. Remainder of the motors ought to stay as it’s.
• You also needs to simulate day and evening utilizing the suitable sensor from the sensor listing. The water movement needs to be set to zero through the night-time, regardless of temperature and humidity values. All of the servo motors ought to come to their zero place, and LCD ought to show water movement as zero% for all 4 models.
• As soon as the simulation is began, it ought to run in a loop. Reflecting any adjustments achieved to the sensor values mechanically by modifying motor positions and values on LCD with out restarting the simulation. Refresh the readings on the LCD show in each iteration. You need to use some delay time contained in the loop in order that displayed values don’t change too shortly.
Hints:
• Discuss with Wokwi documentation for establishing required parts on the simulator.
• For simulating Day/Night time, set the brink sensor worth as 50 models, i.e., if the sensor worth is about to lower than 50 models, your simulation ought to deal with it as evening, and if the sensor worth is larger than 50 models, deal with it as daytime.
Analysis Scheme for Project:
1. Constructing the Circuit within the Simulator (30 Marks)
2. Performance of the irrigation system primarily based on the rule-based mannequin and different anticipated deliverables. (45 Marks)
three. Writing Report for the experiment setup and implementation. (25 Marks)
