CS683: Embedded, Cyber Physical Systems and IoT Security Assignment 1
Common Directions:
• It is a group task with FOUR members in a workforce.
• Solely digital submissions will likely be accepted. Your resolution needs to be submitted through the ipearl emasters platform.
• Just one individual from the group ought to submit the task.
Question Assignment 1 (100 Marks)
Aravind is an formidable farmer who needs 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 needs to construct accommodates servo motors that management the water provide to the farm, based mostly on the current humidity, temperature ranges within the farm.
The irrigation system he needs to construct accommodates servo motors that management the water provide to the farm, based mostly on the current humidity, temperature ranges within the farm. Utilizing sensor knowledge, Aravind needs to construct a wise irrigation system that predicts how a lot water (in share) needs to be provided to his farm. Aravind additionally doesn’t need to water the vegetation throughout night-time.
Nevertheless, Aravind is sweet 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. Determine the required sensors wanted to construct the irrigation system based mostly on Aravind’s necessities from the record of sensors supplied by the simulator. The irrigation system ought to produce the right 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 will likely be supplied to rule-based mannequin as proven in Desk 1 on the Arduino board to foretell the water stream in share. Then the water stream share will likely be supplied as enter to the servo motor (Map the share 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 stream that’s fed as enter to servo motors on an LCD (Check with Determine. 1). The block diagram for the circuit schematic is proven in Determine 2.
Temperature (C) Humidity (%) Water stream 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 got constructed the irrigation system, the sensors used. Additionally, present the hyperlink to your simulated venture within the report (You may generate the hyperlink to your venture from the simulator by signing in and saving the venture).
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 stream in share. Your simulation ought to print the expected water stream % on LCD display and management the servo motor proportional to the water stream %.
• When explicit sensor values are modified, solely the servo motor that makes use of knowledge 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 record. The water stream needs to be set to zero throughout 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 stream as zero% for all 4 models.
• As soon as the simulation is began, it ought to run in a loop. Reflecting any modifications completed to the sensor values robotically 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 rapidly.
Hints:
• Check with Wokwi documentation for organising required parts on the simulator.
• For simulating Day/Night time, set the edge sensor worth as 50 models, i.e., if the sensor worth is ready 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 Assignment:
1. Constructing the Circuit within the Simulator (30 Marks)
2. Performance of the irrigation system based mostly on the rule-based mannequin and different anticipated deliverables. (45 Marks)
three. Writing Report for the experiment setup and implementation. (25 Marks)
