Environmental monitoring
Real-time environmental monitoring with IoT sensors
Measure air, water, soil and weather wherever you need to. Wireless sensors report in real time, alert you when something deviates and give you the data to document compliance.
500+ customers · 100,000+ active sensors · Trusted by Akademiska Hus, Vattenfall, LKAB and HSB
What you can monitor
From indoor climate to groundwater.
Air quality
CO₂, particulate matter, VOC and indoor climate for buildings, schools and cities.
Noise
Keep track of noise levels at work sites and in urban areas.
Water quality
pH, turbidity, dissolved oxygen and conductivity for surface and process water.
Water level and groundwater
Level and pressure sensors for groundwater, wells, reservoirs and tanks.
Weather
Wind, rain, temperature and humidity from weather stations with no moving parts.
Soil
Moisture, temperature and salinity at several depths for agriculture and research.
How it works
From sensor to insight.
Sensors
Battery-powered wireless sensors in the field.
Network
LoRaWAN, NB-IoT, LTE-M or 5G.
Sensor-Online
Real-time dashboards and history.
Alarms and reports
Alerts on deviations and reports for compliance.
Where it is used
Environmental data for real decisions.
Water and wastewater
Monitor wells, reservoirs and treatment plants, document compliance and reduce the risk of contamination or overflow.
Geotechnical monitoring
Follow groundwater levels, soil stability and structural movement in construction, mining and landslide-prone areas.
Cities and buildings
Track air quality and indoor climate, and act before comfort or health is affected.

Which environmental parameters can I monitor?
Air quality (CO₂, particles, VOC), noise, water quality (pH, turbidity, dissolved oxygen, conductivity), water level, weather and soil conditions.
Do the sensors need cabling?
No. Battery-powered LoRaWAN sensors cover large areas without cabling, which suits remote and hard-to-reach sites.
Can I get alerts when values go out of range?
Yes. Set alarm rules and receive notifications by e-mail, SMS, Telegram, webhook or MQTT.
Can I document compliance?
Yes. Scheduled reports can be exported as PDF, Excel or CSV, and the platform keeps a full history.
Can I use my own sensors?
Yes. Sensor-Online is hardware and network agnostic, with decoders for hundreds of sensors and the option to add your own.
