Sercomm Water Sensor

The Sercomm SZ-WTD03 water sensor has a futuristic design, compact size, and a wide variety of additional functions. The sensor will alert you to the presence of water prior to major damage being done, all while being maintenance-free without the need for professional installation.  The sensor also has the ability to be installed as a water bug without wires or mounted higher on a wall and use a probe near the floor to preserve the sensor in the case of high water.

Technical Specs

• Battery Type: CR2 850 mAh capacity
• Dimension: 1.89 x 1.89 x 0.81 in  (48 x 48 x 20.5 mm)
• Operating Temperature: 32 – 122 deg F (0 to 50 deg C)

The Water Detector can be deployed on the ground or mounted on the wall.

Ground Deployment

When deployed on the ground, the Water Detector detects water through the probes protruding from its back cover. Put the Water Sensor on the ground with the back cover facing downward. Possible Water Sensor areas include: in the water heater tray, in the sump pump, at the toilet base, or at ground-level of the basement.

Wall Mounting

• For wall mounting, the Water Detector must be connected to the external extension probe
• Remove the waterproof plug that covers the USB interface.

• Connect the extension water probe into the device terminal.

• The two sensor probes at the end of the cable should be close to the base of the area to be monitored (about 1-2mm away)
• In order for the sensor to work, BOTH probes must have contact with water.  Make sure both probe tips are positioned correctly.
• Use the included adhesive pad to secure the probe housing to a clean, dry surface.
