The SensDesk portal collects and visualizes measurements from HW group devices, such as Poseidon2, Damocles2, HWg-PWR, Ares (including LTE versions), SD-devices or NB-devices. In addition to basic functions, such as providing a concise overview of the states and current readings of detectors and sensors, graphs showing the history of the readings are also available. Graphs in SensDesk can be also used for additional analyses.

To give you a closer look at how some of our devices work, we have prepared a new series of manuals. In this video, we will explore the WLD2 device in more detail.

WLD2 is a WiFi / Ethernet water leak detector with support for WWW, SNMP, e-mails, and PoE. Alarms are triggered by even the smallest volumes of liquids that touch the WLD sensing cable anywhere along the entire length of the cable , such as condensation from A/C pipes or water leaks in general. You will receive alarms before costly damages occur. In addition to water alerts, the device also detects disconnected or damaged sensing cables for increased reliability. WLD2 supports zone creation, 4...
