The purpose of Rodent System is to design an ultrasonic pest repellent. Such a device can be very useful to counter the various problems caused by ants, insects, pests, rodents, etc. The device is compact, cheap, and it does not cause any pollution unlike the other chemical repellents.
J M Services have used a microcontroller to generate sweep in sound frequencies, and an assembly consisting of audio power amplifier, speaker and LCD for this purpose. The technical details of this project follow later. The circuit has been experimentally tested on ants, bugs, and small insects, and it has been successful in repelling them through the generation of ultrasonic frequency sound.
