How it works

From sensor to screen, with no signal cable.

Indoor air quality affects health, comfort and productivity. High CO₂ and other pollutants cause drowsiness and headaches. Measuring is the first step to deciding.

Mode 01

Air monitoring only

The STG MINI measures CO₂, CO, temperature and humidity (or the contracted package) and shows the readings on the web interface, on a computer or phone, over the STG wireless network. No display, no outputs: it only reads and communicates.

Mode 02

Reading in the room itself

The STG QAI adds the 4.3" display on the device and BMS integration over Modbus RS-485. Whoever is in the room sees the air; whoever operates the building does too.

If a reading needs to become action, the QAI already has a relay and a 0–10 V output. See Demand-controlled ventilation.

  1. 01 · MeasurementSTG MINI in the roomThe STG MINI is installed in the room and reads temperature, humidity, CO and CO₂ (or the contracted sensor package).
  2. 02 · ReadingWeb interface and BMSThe readings are available on the web interface and can be integrated into the BMS over Modbus.
  3. 03 · When it becomes actionThe same sensor commandsWhen a reading needs to become action, the same sensor starts commanding a DRV over the STG network (see Fresh air).
What the system delivers

Measure first, decide later.

  • The air of each room, in real timeCO₂, CO, temperature and humidity per measurement point, on the web interface, no app.
  • Several points on the same networkDistributed sensors talk over the STG wireless network and appear together on the web interface.
  • Ready to become controlThe same sensor starts commanding a DRV, or the QAI drives through its own outputs, when the project evolves into demand-controlled ventilation.
