Specification Documentation Guidelines

Dr. Ofer Melamed, ofer.melamed@gmail.com, 0524583263
Objective
The goal of this project is to design and document a complete specification for an IoT
(Internet of Things) software system. The system must integrate hardware and
software components, emphasizing real-time data acquisition, communication,
processing, and storage.
The final deliverable will be a detailed specification document that outlines the full
system architecture, design decisions, tools, protocols, and performance
considerations.
Introduction
The Holon Institute of Technology (HIT) has launched an applied project-based
program in collaboration with industry, aimed at preparing students for real-world
challenges. These projects span diverse domains including smart cities, digital
health, agrotech, defense technologies, and more.
All projects share a common foundation: they integrate three core components —
controllers, sensors/robots, and management software. This specific project
focuses on designing a universal IoT software architecture capable of supporting
these interdisciplinary systems. The goal is to create a flexible, scalable framework
that can be adapted across multiple use cases and hardware configurations.

Final Deliverable: System Specification Document
The document should include the following sections:

1. System Overview
 Define the purpose and goal of the IoT system
 Describe the use-case or application (e.g., health monitoring, environment
sensing, smart agriculture)
 Identify key stakeholders and users

2. System Architecture
 Provide a block diagram of the system (devices, cloud, mobile, dashboards)
 Describe each component:
o Edge device (e.g., ESP32)
o Sensors and actuators
o Communication modules
o Cloud / server
o User interfaces

3. Hardware Specifications
 Microcontroller Selection
o Justify choice (e.g., ESP32 for built-in WiFi + BLE)
o Consider power, GPIO, ADC/DAC, memory, and cost
 Sensor Integration
o Describe different types of sensors (digital, analog, I2C, SPI, UART)
o Define how each sensor connects to the microcontroller
 Drivers and Libraries
o Identify and document available drivers or libraries (in Python
o Provide download sources and usage notes

4. Communication Protocols
 Specify internal communication (e.g., I2C/SPI/UART)
 Specify external communication (e.g., MQTT, HTTP, WebSockets, BLE)
 Discuss encryption/security if relevant
 Describe how data is transferred from device to server/cloud

5. Data Management &amp- Storage
 Describe data formats (JSON, CSV, binary)
 Describe storage strategy:

o On-device (e.g., flash, SD card)
o Cloud (e.g., AWS IoT Core, Firebase, or custom server)
 Define how data is archived, retrieved, and backed up

6. Software Design
 Define the software stack
o Language(s): Python
o Libraries and frameworks
o Logging and error handling
 Include pseudo-code or flow diagrams of key routines
 Define OTA (Over The Air) update method if applicable

7. Performance and Timing
 Specify response times:
o Sensor polling rate
o Data transmission frequency
o System latency (from sensing to dashboard)
 Describe how real-time behavior is handled
 Specify watchdog/recovery mechanisms

8. Development Environment
 Describe the IDE and tools (e.g., VS Code, Thonny, PlatformIO)
 Describe version control tools (GitHub or GitLab)
 Specify how to set up the environment

9. Key Performance Indicators (KPIs)
The document will be evaluated based on:
 Clarity and completeness of system design
 Correct protocol and component selection

 Logical flow and organization
 Quality of diagrams and illustrations
 Justification of technical decisions
 Reusability and scalability of the system design
10. Major technologies
o LoRaWAN- Sensors and gateways
o Node.js - Server
o Python - Server
o Python - AI and Machine learning
o MySQL - relational database
o React - Frontend

Submission Format
 PDF format (up to 15 pages)
 Include diagrams and links to any code or examples
 Optional: link to Git repository
