Abstract
The utility model provides a water drop and water immersion sensor, which is easy to use and is manufactured by winding double groups of wires according to an electrolysis on-off principle. The water drop and water immersion sensor comprises an insulated substrate and two groups of leads which are wound on the substrate at certain intervals in a non-contact way, wherein the two groups of non-contact leads are connected with the anode and the cathode of a power supply respectively, so that a cambered surface or a plane which is wrapped on the outer surface of the substrate and is used for isolating the anode from the cathode. When no water drop enters the cambered surface or a planar area or the sensor is not submerged into water, an anode circuit and a cathode circuit are not communicated with each other; once water drops enter any local area of the cambered surface or the plane, and the water contact diameter is larger than the space between two adjacent positive and negative leads, a water electrolysis process is started, and the positive and negative circuits are communicated with each other; and the working process of the water drop and water immersion sensor is similar to a water signal switch, which is easy to use.
