The electronic rodent control circuit is composed of infrared detection components, electronic switch, high-frequency oscillator circuit, high voltage generating circuit, sound alarm circuit and power components, and the circuit is shown as the chart. Electronic switch is composed of the transistor V1 and related peripheral components. High-voltage generating circuit is composed of the field-effect transistor VF, step-up transformer T2, diodes VD5 and VD6 and so on. High-frequency oscillator is composed of the IC2 and the related external components, and its working frequency is 15kHz. Sound alarm circuit consists of transistors V2 and V3, resistor R5, capacitor C4 and speaker BL and so on. R1 ~ R8 select 1/4W carbon film resistors. C1 and C2 select aluminium electrolytic capacitors with the voltage in 16V; C3 and C4 select monolithic capacitors.
