Moreover, it aids in conserving water resources by preventing over-irrigation and maintaining optimal soil health, leading to vibrant and healthy plant growth that not only beautifies the town but also contributes to its ecological balance.

3. Urban Waterlogging Monitoring

Designed to combat the challenges of heavy rainfall and insufficient drainage. Positioned at crucial junctures, this station utilizes precision sensors to detect and report accumulating water in prone areas. Serving as both an immediate alert system during heavy downpours and a tool for analyzing water retention patterns, it helps city management initiate timely interventions, ensuring streets remain navigable and reducing potential damage to infrastructure.

4. Daily Management Monitoring Station

A blend of past charm and present efficiency. This station integrates cutting-edge technologies with existing infrastructures, such as water and electricity meters. Smart metering, modernizes utilities while reducing human intervention, ensuring both fairness in billing and consistency in service delivery. Additionally, with features like AI visual sensors, it can detect full waste bins, signaling for timely collection and ensuring the town remains pristine and inviting.

Phases of Implementation

The deployment of this comprehensive system is executed in two distinct phases:

  • Phase 1 – Data Monitoring (Advanced Sensing and Datafication): At this foundational phase, the system harnesses advanced sensing technologies to capture high-fidelity data from different environmental aspects.
  • Phase 2 – Data Application (Decision Aid and Intelligentization): This stage is an upgrade from the initial phase. It leverages sophisticated analytical and AI tools to provide actionable insights from the gathered data.


Three stations are now strategically placed:

  1. Multi-functional Intelligent Ecological Meteorological Monitoring Station
  2. Soil Moisture Monitoring Station
  3. Daily Management Monitoring Station
