Sensor Placement and Mounting
SENSORS
• The sensor will work best when simply placed on a floor.
It will begin to detect water at 0.787mm (0.031 inches).
• Use the hole at the top to hang your sensor
from the back using a nail. Or, insert one
mounting screw through the front of your sensor.
• Mount your sensor on a north-facing wall or in
any shaded area. Under an eave or deck rail is
preferred to avoid inaccurate readings from
the sun.
• The maximum wireless transmission range to
the station is up to 121 meters (400 feet) in open
air, not including walls or floors.
• Be sure your sensor is mounted vertically,
to allow moisture to drain out properly.
• If sensor is placed vertically (i.e. hung
inside a sump pump) the depth of the
water needs to be at least 6.35mm
(0.25 inches) high to trigger the sensor.

Water Leak Sensor LED Light
Blue Light: Normal Transmission
The light will occasionally flash blue,
indicating it is still transmitting correctly
and no water has been detected.
Red Light: Water Detected
The LED light will flash red twice every
5 seconds until dry.
Purple Light: Low Battery
Indicates the sensor batteries need
to be replaced.
IMPORTANT:
The metal contacts on the sensor should not be in contact with other metal.
This will cause false WET readings and may damage the sensor.
