STG MINI

Measure CO₂, CO, temperature and humidity in the room. Reading and communication sensor, no control outputs.

Measures

Four quantities, one reading.

The STG MINI is the entry sensor of the STG ecosystem. It sits in the room, at the point where the quantity must be measured, and makes the readings available on the web interface and on the network.

Temperature0 to 45 °C
Humidity0 to 100% RH
Carbon dioxide (CO₂)400 to 10,000 ppm
Carbon monoxide (CO)0 to 500 ppm

Sensor combinations

Temperature and humidity
CO₂
CO
CO + temperature and humidity
CO₂ + temperature and humidity
Multi-sensor: CO₂, PM2.5, VOC, temperature and humidity

Each STG MINI leaves the factory with one of these combinations. Engineering confirms the package in the quote.

How it works

Two ways to use the same sensor.

Mode 01

Standalone monitoring

The MINI reads the room and shows the readings on the web interface, on a computer or phone, over the STG wireless network.

Mode 02

Paired with the DRV

When a reading needs to become action, the MINI sends the command over the STG wireless network and the DRV, at the fan, executes it. Several MINIs can command the same DRV through the configured rule.

The STG DRV commands single-phase AC or EC fans: on/off through the relay and speed through the 0–10 V output.

One unit per DRV, as the project defines.

The MINI measures and communicates. The DRV executes the command at the equipment.

Where to use

Main applications.

Car park with an exhaust fan on the ceiling

Car parks

Distributed CO sensors and one DRV per unit.
