Abstract
A rainwater detection device for detecting rainwater is provided. The rainwater detection device includes: a panel having a surface; rainwater sensing wires on the surface; and a rainwater sensor (i) physically connected with the rainwater sensing wires without an electrical connection if a condition is unsatisfied and (ii) physically and electrically connected with the rainwater sensing wires if the condition is satisfied; wherein a first wire, one of the rainwater sensing wires, is separated from a second wire, another of the rainwater sensing wires, by an interval, without contacting each other and wherein the rainwater sensing wires are connected to opposite polarity of an electrode connected with the rainwater sensor, and wherein the condition is that a first state where no current flows between the first and the second wires is changed to a second state where current flows between the first and the second wires due to the rainwater.
