SCEMS - Smart Community Environment Monitoring System

This repository contains the software-only implementation of
SCEMS (Smart Community Environment Monitoring System)
for the UFTB Robotics Club – IoT & Robotics Contest 2025 (Senior Category).

📌 Problem Overview

Gazipur’s Hi-Tech Industrial Zone faces:

• Poor air quality
• Rapid heat stress
• Unstable soil moisture
• Overcrowded public transport points
• Night-time security risks
• High energy waste due to static street lighting

SCEMS monitors these factors using simulated virtual sensors in Wokwi and performs alert classification with a Python backend.
