Steps for Final Year Undergraduate IoT Project: Smart Irrigation Using Favoriot Platform

Phase 1: Planning and Preparation (Semester 1)

Problem Identification and Objectives:
- Identify the problem (e.g., water wastage in agriculture) and define project goals.
- Research the advantages of using IoT for smart irrigation.
- Set objectives like real-time monitoring of soil conditions, automated irrigation, and water usage optimization.
Literature Review:
- Study similar IoT-based smart irrigation systems.
- Understand the features of the Favoriot platform and how it can be integrated.
System Design:
- Design the system architecture:
  - Sensors → Microcontroller → Favoriot → User Dashboard/Notifications.
- Plan sensor placements and the system’s data flow.
Component Selection:
- Hardware:
  - Soil moisture sensor (e.g., YL-69 or capacitive soil moisture sensor).
  - Temperature and humidity sensor (e.g., DHT11 or DHT22).
  - Optional: Water flow sensor (e.g., YF-S201).
  - Microcontroller: NodeMCU (ESP8266) or ESP32 for Wi-Fi.
  - 5V relay module to control water pump or solenoid valve.
  - Water pump or solenoid valve.
  - Power supply: 5V/12V adapter or battery.
  - Additional components: Jumper wires, breadboard, or PCB, and a plastic enclosure.
- IoT Platform:
  - Subscribe to the Favoriot platform (MYR 15/month or MYR 100/year for student plans).
Budget Estimation:
- Create a detailed budget, including hardware, software, and platform subscription costs.
Proposal Submission:
- Write and submit a project proposal, detailing the problem, objectives, system design, and budget.

Phase 2: Development and Testing (Semester 2)

Hardware Assembly:
- Connect soil moisture and DHT11 sensors to the microcontroller.
- Wire the relay to the water pump or solenoid valve.
- Secure all components in a weatherproof enclosure.
Software Development:
- Program the microcontroller using Arduino IDE:
  - Read data from sensors.
  - Send data to the Favoriot platform using its REST API.
  - Receive commands for controlling the pump or valve.
- Test the code in a simulated environment before deployment.
Integration with Favoriot:
- Create a Favoriot account and set up the project.
- Configure data streams to collect and visualize sensor data (e.g., soil moisture, temperature).
- Build a dashboard for real-time monitoring and remote control.
Testing:
- Perform individual tests for sensors, connectivity, and actuators.
- Test data transmission to the Favoriot platform.
- Simulate irrigation automation and manual override scenarios.
Field Deployment:
- Install the system in a small plot or garden.
- Monitor performance over a trial period.
Analysis and Optimization:
- Analyze data collected via Favoriot (e.g., water usage, soil moisture trends).
- Adjust sensor placements or system parameters based on observations.
Final Report and Presentation:
- Document the project, including system design, challenges, and results.
- Prepare a presentation and demonstrate the smart irrigation system.
