The SD-WLD Water Leakage Detectors with WiFi can detect water leaks using a moisture-sensing cable which can be up to 85m in length. The total cable run can be extended to 185m using an 85m sensing cable and a 100m connecting cable. The sensing cable is very sensitive and can detect conductive liquid droplets and can be used to detect condensation and prevent damage from small water leaks and adverse environmental conditions.

For configuration the SD-WLD has a built-in web server and WiFi connectivity and the device can be remotely monitored over the internet using the HWg Cloud or SensDesk portals or SensDesk Mobile App (iOS or Android). Using the portals the device can send email alerts. Text messages (SMS) can also be sent, if an SMS-GW3 module is attached to the network or using an email-to-text SMS service.
