Abstract

The propose of this project is to built an electronics multi repellent that can chase out the insects or rodent animal that may bring dangerous to health from home. Ultrasonic sound is a frequency that is too high to be heard by the human ear .In fact, ultrasonic waves behave more like light than sound. The sound will radiate outward in a cone shape. People can hear sounds from 20 to 20,000 cycles per second, while dogs and cats can hear up to 27,000 cycles per second. This electronics multi repellent is designed to continually and automatically sweep an ultrasonic frequency and to give the users a complete set of repellent that can chase out not only one type of animal. The user just needs to select the switch depend on the types of animals or insects that they want to repel. Normally, new animal will almost always replace the ones you've killed. Using ultrasound in your pest control efforts can result in long-term reductions of animal populations. These devices are appealing to consumers because they are silent to human ears and don't involve any traps or poison. Reduction in rodent and insects activity is in 6 to 10 days on average. One should never expect instantaneous results.
