Abstract
A water sensor and activation assembly including a paper element to sense the presence of water leaks from appliances such as clothes washing machines, refrigerator ice makers and the like, and to cause an associated water shutoff valve to turn off the source of water leakage. The water sensor, in conjunction with the shutoff valve, operates without any electrical power requirement. The design allows the water sensor to operate in a high humidity environment.
