When a mouse touches the sensor between A,B, V1 and V2 will be connected and C3 begins to charging. When the voltage reaches a certain level, V3 and V4 will be connected, making K connected, and the alarm circuit and high voltage output circuit begin to work. IC will output music signals, which will drive BL to make a warning sound. The other circuit will send the alarm signal through W, which can be received by the users within 1km with a FM radio. At the same time, VL1 and VL2 are illuminated, high voltage generator begins to oscillate and generate a pulse high voltage, which will kill the mouse.
