Indoor air quality monitoring.

Know the conditions of the room with accurate sensors, without driving any equipment.

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.
