Classroom IAQ Monitoring
Masalahnya
CO2 in full classrooms rises quickly and affects concentration, but schools have no sensors and parents ask for evidence that rooms are ventilated.
Ikhtisar solusi
MILESGO gateways collect data from indoor air quality sensors (CO2, PM2.5, TVOC, T/RH), CO2 sensors, LoRaWAN wireless sensors over LoRaWAN / Modbus RTU, and deliver it to a cloud platform (MQTT), large-screen dashboards (HDMI), the BMS as MQTT / BACnet/IP. Field equipment keeps its own protocol and control logic; integration is done by configuration and point mapping, not custom code.
Typical scope
- indoor air quality sensors (CO2, PM2.5, TVOC, T/RH)
- CO2 sensors
- LoRaWAN wireless sensors
Protocol path
LoRaWAN / Modbus RTU → MQTT / BACnet/IP
Implementation checklist for the project manager
- Run a LoRaWAN coverage survey and pick the regional band (EU868 / US915 / AU915 / AS923 / KR920 / CN470) before ordering.
- Agree sensor positions (height, airflow, distance from doors and diffusers) so readings are representative.
- Keep sensor calibration certificates on file and plan recalibration intervals.
- Fix a site / asset naming convention before the first site so data from all sites can be compared.
- Roll out in phases: pilot one site or area, confirm data quality, then replicate.
- List dashboard users and roles, and configure user permissions accordingly.
Project deliverables
- Signed point table and protocol mapping
- Gateway configuration files and backups
- IP address plan and network drawing
- FAT and SAT test records
- As-built documentation and operator training
Arsitektur sistem
Field layer: indoor air quality sensors (CO2, PM2.5, TVOC, T/RH), CO2 sensors, LoRaWAN wireless sensors, connected over LoRaWAN / Modbus RTU. Edge and integration layer: MILESGO protocol gateways and edge controllers, mounted on DIN rail in existing panels, polling each device, time-stamping values and buffering them locally. Upper layer: a cloud platform (MQTT), large-screen dashboards (HDMI), the BMS, which receives the data as MQTT / BACnet/IP. Remote access for maintenance runs over VPN rather than open internet ports.

Langkah pelaksanaan
- 1
Site survey and point list
Inventory devices, protocols, register maps, panel space, power and network paths.
- 2
Design and point table sign-off
Map every point to the target protocol and system; agree it with the client and the upper-system contractor.
- 3
Configuration and FAT
Build the gateway configuration off site, simulate it and test against the signed point table.
- 4
Installation and wiring
Mount gateways on DIN rail, wire RS-485 / I/O / Ethernet, apply the IP plan.
- 5
SAT and alarm tests
Verify values against local readings, test every alarm and command end to end.
- 6
Handover and support
Hand over configuration backups, point table and as-built documents; train operators.
