SHEET 01 · Case story

Check the classroom air-quality record to see how the room feels.

The school connects air-quality and temperature/humidity sensors, with overviews, trends and threshold reminders by classroom. Staff can look up environmental changes by area and time.

SHEET 02 · Challenge and response

From the site problem to a system approach.

  1. 01The challenge

    Air-quality and temperature/humidity readings may not be visible in time and may lack historical records.

  2. 02The system approach

    Connect IAQ and temperature/humidity sensors to create site overviews, threshold alerts and trend records.

  3. 03Reported outcome

    Make air-quality management data continuously available for lookup instead of relying on single readings.

SHEET 03 · Architecture

System architecture and data flow.

An Environment Gateway collects IAQ data; the platform provides monitoring and alert views by classroom or area. Source diagrams retain some original Traditional Chinese labels.

SHEET 04 · Wiring and hardware

Wiring diagrams and hardware configuration.

The diagram outlines data flow between site signals, edge devices, the network and the platform. Confirm installation and connection scope before work begins.

SHEET 05 · Before implementation

What to confirm before work begins.

This material describes a planning direction. Confirm site points, installation, report definitions and alert rules against actual site conditions.

  1. 01Site points and signal sources
  2. 02Communication protocols and network conditions
  3. 03Power, panels and installation method
  4. 04Report fields and data definitions
  5. 05Alert rules and responsible people
