Product description: According to the principle of bionics, the humaninventthe device which can drive birds and mouse using ultrasound in each field. In order to drive birds effectively in the protected areaby people, weconfirm the most effective ultrasonic frequency range under the help of experts in birds. Then we invent the ultrasonic birds repeller using advanced technology, fixed frequency and sweep frequency transformation mechanism. The ultrasonic equipment greatly extend the adaptive time within the scope of ultrasonic equipment role, destroyed the living environment from birds in effective range, which can drive birds from the scope of protection of ultrasonic equipment. The device can be used in airport, electric power, agriculture, fisheries breeding and workshop warehouse, cultural relic protection, etc widely.
