The discovery of water leaks occurred in the late 1970s when the computer room was still in its infancy. The computer room, as it is today, contained an air conditioner filled with water for humidification and sometimes cold water for cooling. 

Due to a large number of electrical cables, data cables, and piping needed in the room, the floor has been raised and is still used to hide all services. Unfortunately, this water leak under the raised floor was not detected until the power/data connection was flooded and the computer stopped functioning.

In the mid-1980s, water was recorded with a point sensor. This unit consists of an etched circuit board or two metal electrodes. The water sensor is implemented using a DC voltage on one sensor while the return signal is searched for in another sensor. If no return signal is visible on the reverse sensor, there is no water. The problem with using this type of system is sensor erosion due to electrolysis and limited water detection areas. Water can leak out of the sensor and be detected too late.

Water detection cables were developed in the mid-1980s. The advantage of this type of detection is that water is detected along the cable. This makes it possible to pass through any water-containing areas or equipment, ensuring that leaks are detected regardless of the direction of water flow.

Since the mid-1980s, progress has been mainly made in alarm panels and water leak detection. Today you can receive text messages, email, take calls, record them in the building management system, or just have a simple bell and light.
