Water and environment

IoT water quality and environmental monitoring

Collect data from wired and wireless sensors in lakes, rivers, reservoirs and treatment plants, and bring it into one platform, with the option to hand it on to PLC and SCADA systems.

Sensors that report from remote sites

With Sensor-Online you collect sensor data from remote, battery-powered loggers over LoRaWAN or cellular networks, as well as from wired instruments. The platform stores the readings, shows them in dashboards and maps, and raises alarms when values leave your limits.

If you need to, the data can be converted to Modbus or OPC UA, so it fits straight into existing PLC and SCADA systems. Combining IoT sensors with PLC and SCADA gives you real-time data acquisition, analysis and control, which improves efficiency, safety and operations.

20 applications for water and environmental monitoring

From drinking water to ecosystems.

Water quality

Turbidity and suspended solidsShows water clarity and quality, which matters for aquatic life and drinking water safety.
SalinityDetects salinity changes that affect freshwater resources and agriculture.
Dissolved oxygenReal-time oxygen levels help keep aquatic environments healthy and prevent fish kills.
pH levelManages acidity and alkalinity, important in aquaculture and water treatment.
ConductivityIndicates dissolved salts and other chemicals in the water.
TemperatureWater temperature affects chemical reactions and biological processes.

Levels and flow

GroundwaterMonitor groundwater levels to support sustainable use and prevent over-extraction.
Surface waterFollow levels and quality in lakes and other surface water.
Water depthDepth data supports flood management, reservoir operations, recreation and irrigation.
Flood detectionReal-time level and flow data give early warning for floods and disaster management.
StormwaterDetect pollutants in stormwater and prevent contamination of natural water bodies.
Reservoir managementFollow quality and levels to keep storage and distribution efficient.

Ecosystems and impact

AlgaeContinuous algae monitoring helps manage algal blooms that can harm aquatic life and people.
Chlorophyll-aShows photosynthetic activity and indicates algae and overall water health.
Rivers and streamsFollow the health of rivers and streams over time.
Catchment areasProtect water resources from pollution and overuse.
Industrial effluentTrack discharges so limits and permits are respected.
Agricultural runoffFollow runoff levels to prevent pollution and manage fertiliser use.
AquacultureKeep conditions right for fish and other aquatic organisms in farms.
Environmental impact assessmentData for assessing the impact of industrial and agricultural activities.

Benefits of IoT sensors with PLC and SCADA

Better decisions, from data you can trust.

Real-time data collection

Continuous monitoring keeps your data up to date and ready to act on.

Better decisions

Real-time data processed by PLCs and shown in SCADA supports quick, informed decisions.

Lower cost

Automated monitoring reduces manual sampling trips and gets problems found sooner.

Fits existing systems

Convert to Modbus or OPC UA and keep your current control and reporting systems.

From water to decision

How the data travels.

Measure

Sensors and loggers measure level, quality and flow on site.

Transmit

Data is sent over LoRaWAN or cellular networks.

Convert

Values can be converted to Modbus or OPC UA for PLC and SCADA.

Act

Alarms and reports tell you where to look first.

Frequently asked questions

Which water quality parameters can I monitor?

pH, conductivity, dissolved oxygen, turbidity, salinity, temperature, chlorophyll-a and algae, as well as water level and flow, using online sensors.

Do the sensors work in remote places?

Yes. Battery-powered sensors report over LoRaWAN or cellular networks, so they can be placed where there is no cabling.

Can the data go to our PLC or SCADA system?

Yes. Sensor-Online can convert the data to Modbus TCP or OPC UA so existing control systems can read it.

Can I be warned about floods or pollution?

Yes. Set alarm limits and receive alerts by e-mail, SMS, Telegram, webhook or MQTT when readings cross them.

Does monitoring replace laboratory sampling?

No. Keep your own sampling and compliance routines alongside the monitoring. The sensors add continuous data between samples.
