Leak detection
IoT water leak detection: find leaks before they become damage
A small leak can turn into expensive damage. Wireless leak sensors and meter data show where water is where it should not be, and Sensor-Online alerts the right people.

How it works
From drip to alert.
Place sensors
Under pipes, in technical rooms, near machines and along rope sensors.
Connect
Battery-powered sensors report over LoRaWAN or other low-power networks.
Detect
A sensor reports water, or meter data shows unusual flow.
Alert
The platform notifies the right people by e-mail, SMS, Telegram, webhook or MQTT.
Ways to catch a leak
Combine sensors and meter data.
Spot leak sensors
Small sensors that report when water reaches them, for floors, technical rooms and under equipment.
Rope and cable sensors
Rope-type sensors cover longer runs, and positioning versions help show where along the cable the leak is.
Meter data
Water meters show continuous or unusual flow that points to a leak in the pipes.
Pressure and levels
Falling pressure or tank levels can reveal a leak in a network.
Status and battery
See which sensors are online and when batteries run low.
Response
Rules can send downlinks to compatible devices, such as a relay controller, as part of your response plan.

Leak sensor or meter data?
They find different things, and work well together.
| Leak sensor | Meter data | |
|---|---|---|
| What it detects | Water at a specific spot | Unusual flow in the pipe |
| Best for | Floors, technical rooms, under equipment | Hidden leaks and whole properties |
| Good to know | Needs a sensor at the right place | Needs a meter that reports regularly |
What the platform does
From alarm to action.
Alerts
Alarm rules notify the people who need to act.
Know where
Place sensors on a floor plan and use tags for building and room.
History
See when a sensor reported water and how it developed.
Many properties
Handle many buildings and customers in one platform, with views per role.
Reports
Export events and history as PDF, Excel or CSV.
Open integrations
Pass alarms on to other systems through the REST API, webhooks or MQTT.

Which leak sensors do you offer?
Our catalogue has spot leak sensors, rope-type sensors and leak detection with location, from several manufacturers.
How fast will I be notified?
The platform sends an alert as soon as it receives a reading that matches your rule. How soon a sensor reports depends on the device and its settings.
How do I receive alerts?
By e-mail, SMS, Telegram, webhook or MQTT, depending on how you set up the alarm.
Do the sensors need wiring?
No. They are battery-powered and wireless, so they can be placed where water is likely to appear.
Can I find where the leak is?
Each sensor has a known location. Rope-type sensors with positioning can also help show where along the cable the leak is.
Can I use meter data as well?
Yes. Water meter readings can show unusual flow, and rules can raise an alarm when consumption looks wrong.
