The GOGO Sensor your child wears is specifically designed to recognize moisture and will alert you and your child that they have wet their bed. The accuracy and immediacy of these moisture alerts will often stop your child from fully wetting the bed. These moisture alerts are used by the GOGO Band System to develop your child’s own personalized “bladder-full” predictive alert. The GOGO Band System will not function without the GOGO Sensor. This replacement sensor will seamlessly work with your child’s current GOGO Band System.
