CO₂, temperature & humidity
Three air measurements. One LoRaWAN sensor.
Follow air conditions across your site
Monitor CO₂, temperature and humidity in production spaces, offices and storage areas. Battery power makes it easy to add measurement points. The M4 keeps their history locally, ready to review in your browser or connect to your building systems.
- CO₂ concentration
- 400–10,000 ppm
- Measurements
- CO₂ + temperature + relative humidity
- Installation
- Battery powered · LoRaWAN · IP66
Three readings. A clearer view of the space.
Ventilation patterns
Follow how CO₂ concentration rises during use and falls as the space clears or ventilation changes.
Temperature changes
Compare air temperature between spaces and shifts, alongside the activity in your building.
Humidity trends
See when moisture levels change around production, stored materials or occupied rooms.
Choose a representative measurement point
Mount the probe facing down in representative airflow, away from direct sunlight and nearby heat. Keep the complete CO₂ sensor within 0–50 °C and non-condensing conditions.
See the working day in your measurements
Read all three values together, then open the history to compare changes between shifts or spaces. The example shows repeated CO₂ rises and recoveries across three days.
The sensor reports over LoRaWAN to a compatible interface on the M4. Your readings stay in its local database, with browser access and OPC UA or MQTT integration for your own systems.
