Introduction
Water can enter a building in many different ways and, in some cases, remain undetected. This
can cause damage and problems to sensitive electronic equipment. Computer and mainframe
rooms which have a false floor and ceilings could harbor undetected water, which is only detected
after a problem occurs.
The ropeWater sensor is capable of detecting the presence of or non-presence of water. It
contains a microprocessor controlled capacitance measuring circuit which is far more precise
than commercially available standard water detectors which measure the resistance of water.
The detector provides feedback to the web based interface which will indicate the
presence/absence of water with a Normal/Alert, or Critical indication. The unit will retain any error
condition until it is read via a
snmpget
. Therefore, if it encounters a critical condition at any time, it
will report that condition before it returns to a normal state.
The value of the status for the SNMP OID for the ropeWater sensor can be Normal, No Status,
Critical or Sensor Error.
