Solar energy driven autonomous smart ultrasonic mosquito repeller system

Few hundred species of mosquitoes cause disease like malaria, dengue etc. In order to eradicate these malaises, people have resorted to many remedies like chemical repellents which causes nervous breakdown, increase blood pressure and also ravage crops in the fields. In order to overcome these plight, solar energy driven autonomous smart ultrasonic mosquito repeller system has been proposed. The proposed system is driven by solar energy employing dynamic offset feed mirror parabolic dish integrated with solar panel. The proposed system is harmless to human beings as it produces ultrasonic sound waves by utilizing piezoelectric effect. The frequency range of ultrasonic sound waves is above 20 kHz which are inaudible to human beings. The ultrasonic sound waves of frequency range 38 kHz-44 kHz are audible to mosquitoes and other insects. When mosquitoes and other insects communicate, they continuously sense ultrasonic sound waves from repeller through antenna present on their body, they get irritated and are forced to repel away from that area. The microcontroller Atmega 328P-PU is used to turn on and off the repeller. The proposed system can be effectively used to repel mosquitoes from lawns, city parks, universities campus and organizations. The proposed smart mosquito repeller system is effective within 255 square meters.
