PURPOSE: A bird eliminator with an infrared sensor is provided to enhance the bird eliminating efficiency by reducing the adaptive capability for environment and sounds of birds only if the birds approach within a certain distance. CONSTITUTION: A solar battery(600) is connected to a storage battery(620) and used to drive components. The solar battery using a solar cell feeds solar energy to the storage battery after converting the solar energy into electric energy to apply to farmlands including fruit gardens. A power control unit(640) efficiently controls power depending upon the brightness of light by feeding power during day and isolating the power at night. A signal detected from a sensor maintains the continuous state during a certain time to generate sounds for eliminating birds at random if birds approach. Therefore, a bird eliminator improves the bird eliminating efficiency by preventing the birds from adapting to sounds. |
