Water Sensors
Each WeatherGoose Climate Monitor (except the MiniGoose) contains a three-port I/O connector, called the “C123C” port. Up to three individual water sensors can be attached to this port. If more sensors are needed, they can be wired in parallel and report as a group.
The I/O ports are supplied with a +5VDC supply voltage which senses whether water is present due to the change in conductivity in the water sensor.
The water sensor can show whether the sensor is dry, damp, or completely immersed in water. Increasing dampness will be shown as a downward trend in the graph as conductivity increases.

Conductivity Bridge
The water sensors continuously measure the conductivity of the environment they are immersed in. In dry air, the reading should be about “99”. When placed in a glass of tap water the reading should be around “50”. Intermediate values show the conductivity increasing as the reading decreases.
The sensors connect to the WeatherGoose with 24 AWG solid copper wire. Runs of over 100 feet can be used.
Prevent Sensor from Moving
Most sensors are mounted out of sight under flooring, in pipe closets, or in overhead water catch trays. If the cables are moved, there is a possibility of the sensor losing its most sensitive position or becoming airborne. Some users place bricks on their water sensors, but ITW recommends tie-wraps or epoxy glue to wooden brackets.
When mounted in a metal tray, mount the sensor face down on an insulating surface such as a vinyl floor tile. Secure the sensor with tie wraps or wooden brackets.
Testing the Sensors
ITW recommends testing the water sensors to verify that the each water sensor sends an alarm and that the e-mail arrives at the proper address. Testing requires the sensor be immersed in a cup filled with water and the transmission of the alarm verified.
Cable Length
Cable runs of 100’ and over are common. Use 22 or 24 AWG solid wire for easy insertion into the C123C I/O ports.

Connect the sensors to the C123C block. “C” is common (ground). If more than three door sensors are to be used, they can be wired in parallel (not series). When wired in parallel, in the event that one sensor becomes wet they will all alarm as a group.
