Abstract: A gardening tool with identification function including an operating unit and a working unit is provided. The operating unit includes a first main body, a first electrical connector, and an operating device. The first electrical connector is set at one end of the first main body. The operating device includes a processor electrically connected to the first electrical connector. The processor stores operating parameters. The working unit includes a second main body, a second electrical connector, a motor, and a work piece. The electrical property of the second electrical connector is corresponding to one operating parameter in the processor. When the second main body is connected to the first main body, the second electrical connector is electrically connected to the first electrical connector. The processor selects one operating parameter according to the electrical property of the second electrical connector to control the output rotational speed or power of the motor.
