Parsa is not comfortable with some insects especially didn't like cockroaches, so we decided to build a device together that could repel insects without killing them. with my help , we designed the circuit, built it together, and tested it, and the result was great. This method solved the problem peacefully and without aggressive interference with nature.

Yes, for this purpose, instead of piezo, an ultrasonic sensor in the 40 kHz frequency range must be used
