SD-WLD is a simple detector that detects water leaks using a moisture-sensing cable. It allows connecting 1 sensing cable of up to 85m in length. The total wiring length can be up to 185m (85m sensing cable + 100m connecting cable).
The sensing cable detects as little as a few drops of conductive liquid, so it can be also used to detect condensation.
Thanks to early detection and alerting, SD-WLD can prevent substantial damages caused by unexpected adverse environmental conditions.
For configuration, SD-WLD features a built-in web server and WiFi connectivity. The device can be monitored remotely over the Internet using any SensDesk Technology portal and the SensDeskMobile app.
If the device is correctly configured in the SensDesk portal, it can send an e-mail alert whenever the specified range of values is exceeded. If you also use our SMS-GW3 together with the portal, the alerts can be also sent as text messages (SMS).

2D area flood detection requires the installation of a detection cable in a place where water will likely be located after leakages from various sources of flooding (cracked water pipes, glycol from the cooling system, wastewater).
HW group offers several products that provide ideal solutions for flood and water leak detection.

SensDesk Technology portal is required
The SensDesk Technology is a portal solution from the HW group to manage remote sensors and devices (only for HW group products). Portals offer a central overview of all the values and provide a variable combination of features like sending the alarms, reporting, history record, outputs into the Open API etc.
- SD Device has to be connected to any SensDesk Technology-based portal (SaaS).
- There are several Portal providers available, users can migrate the device between their portals.
- The Manufacturer provides a limited free portal (HWg-cloud.com) as the default pre-configured option.
- Even the free & limited portal service (HWg-cloud.com) can send email alerts and offers basic remote device management.
- One of the available portals is paid service www.SensDesk.com
- Several subscription plan options
- SMS / Voice call alerts to any mobile phone
- Graphs / MultiGraphs (data history)
- PDF reports
- Email alerts/alarm escalation
- Open API: All sensor values are available via XML / SNMP protocols
