Electronic mosquito repellent machine. In recent years mosquito is one of the harmful insect for mankind owing to the deadly, infectious diseases associated with the mosquitoes’ bites: malaria, elephantiasis, yellow fever, etc. Malaria is a major disease that mostly affects the people living in humid and other parts of the world.
Aug 12, 2020·The circuit can also be tweaked to generate sound within the human listening range. This can be done simply by replacing C1 with any other capacitor having value in between 0.02 and 0.1 uF. Insect Repeller using IC 555. Using an uninterrupted sound frequency to repel or attract insects may actually be possible in real life.
The circuit here is nothing but an astable multivibrator wired around NE555 (IC1). The cat repellent circuit produces an ultrasonic sound in the range 15-20Khz. The NE 555 is enough to drive a small piezo buzzer and no amplification stages are needed. The POT R2 can be used to adjust the frequency of sound. Cat Repeller Circuit diagram with ...
