The WaterBug® Unsupervised Water Sensor ("W-S-U") is a water detection sensor ideal for computer rooms, document storage areas, warehouses, sump pumps and basements. WaterBug sensors activate the alarm when a conductive bridge is formed between 2 contacts. The sensors will not alarm for high condensation. Must use with WB200 or WB350. This is not a stand-alone product.


  • • Unsupervised sensor for the presence of water. Can be used with WB200 to monitor for the absence of water.
  • • Must use with WB200 or WB350. This is not a stand-alone product.
  • • Up to 6 sensors can be located up to 100' (30.48m) away from the WB200 and WB350 devices for a wide area of protection. Use 18-22 AWG twisted pair wire for extension of sensors from the device.
  • • Ensure that power running to the device does NOT have a connection to earth ground. This could result in a failure to detect water or ground fault.
  • • Stable surface mount design.
