Smart industry
IoT for predictive maintenance: act before equipment fails
Wireless sensors on motors, pumps, fans and other critical equipment show how each machine behaves over time. Sensor-Online turns the readings into trends and alerts, so maintenance can be planned instead of reacting to breakdowns.

How it works
From sensor to maintenance decision.
Fit sensors
Battery-powered wireless sensors on motors, pumps, fans and other critical equipment.
Collect
Data travels over LoRaWAN, NB-IoT or LTE-M to the platform.
Analyse
Trends and thresholds show how each machine behaves over time.
Act
Alerts and integrations turn a warning into a planned job.
What you can monitor
Sensor types from our catalogue for industrial equipment.
Vibration
Vibration sensors for rotating equipment such as motors, pumps and fans, from several manufacturers.
Temperature
Rugged temperature sensors and probes for bearings, housings, process pipes and cabinets.
Machine status and counters
Digital inputs and pulse counters report on/off status, cycles and running time.
Process signals
Analog interfaces for 4–20 mA let you bring existing process instruments online.
Levels
Radar level meters for tanks and silos.
Assets that move
Trackers help you locate equipment and tools around the site.
Example sensors from our catalogue
A few of the devices that work with Sensor-Online. The catalogue has over 1,000.
From readings to decisions
What the platform does with the data.
Trends and history
Time-series graphs and change charts show when a machine starts to drift.
Alarms
Set thresholds and get alerts by e-mail, SMS, Telegram, webhook or MQTT.
Combine signals
Use the rule engine to look at several readings together, for example vibration and temperature.
Maintenance tickets
Use Node-RED or n8n to create a ticket in your maintenance system when an alarm fires.
Control-system link
Pass values to your PLC or SCADA over Modbus TCP or OPC UA.
Reports
Export history as PDF, Excel or CSV for service and follow-up.
Reactive, preventive or predictive?
Three ways to run maintenance.
| Reactive | Preventive | Predictive | |
|---|---|---|---|
| When you act | After something breaks | At fixed intervals | When the condition says so |
| What it costs you | Unplanned stops and rush repairs | Some work done earlier than needed | Work planned around real wear |
| Data needed | None | Calendar and running hours | Readings from the equipment itself |
Start with your most critical asset
A small pilot teaches you a lot.
Choose one machine where a stop is costly, add a vibration and a temperature sensor, and follow the trend for a few weeks. The Starter Pack gives you pre-selected sensors. Contact us for the exact scope and price.

What is predictive maintenance?
It means using condition data from equipment, such as vibration and temperature, to decide when maintenance is needed, instead of waiting for a failure or following a fixed schedule.
Which sensors can I use?
Vibration, temperature, digital status and counters, analog 4–20 mA signals, levels and asset trackers. Browse the industrial devices in our catalogue.
Do I need to replace my control system?
No. Wireless sensors are added alongside your existing equipment, and values can be passed on to your PLC or SCADA.
How do I get notified?
Set alarm rules and receive alerts by e-mail, SMS, Telegram, webhook or MQTT.
Can it connect to my maintenance system?
Yes, through the REST API, webhooks, MQTT, or low-code flows with Node-RED and n8n.
Can it run on our own servers?
Yes. Install Sensor-Online on-premise, with access only to your intranet if you need it.
