Best Electronics Project Freaky Diodes Circuit Diagram About Electronic Mosquito Repellers: How does the Electronic Mosquito Repeller work? An Electronic Mosquito Repeller repels moquitoes by using a small speaker or piezoelectric disk to generate ultrasound.Ultrasound - Sound that has a frequency of more than 20kHz is called Ultrasound. It usually cannot be perceived by the human ear.
Male mosquito emits ultrasonic waves to in the search of food. When these waves came in contact with any female mosquito, she find a place to hide or to fly back to other area. Using the same idea we can create a repellent circuit which can produce ultra sound of the desirable frequency to repel the female mosquito.

Many of us are familiar with ointments, etc that repel mosquitoes. But, very few know those elements can be harmful to human skin. However, an electronic mosquito repeller is comparatively adequate, especially for heated areas and humid climatic regions. It gives ultrasound waves by the speaker present in the circuit. This electronic mosquito repellent circuit is easy to build but is kind of hard to adjust on the exact sound frequency which will repel the mosquitoes. The heart of this circuit is a NE555 Timer IC. The IC possesses an oscillation frequency ranging from 670 to 680 Hz. The concepts of these mosquito repellers are simple and we can build a simple electronic mosquito repellent circuit at home easily by using 555 timer IC and a few other commonly available components. Let's see the concept of a mosquito repellent circuit with the help of a video in detail
An insect repellent or a mosquito repellent is a simple electronic circuit that repels small insects such as mosquitoes & flies on the principle that insects can be repelled by exposing them to sound frequencies in the ultrasonic region (above 20KHz). Insect repellent circuits are cheap & easy to design.
How to make Mosquito Repellent Circuit using 555 Timer Circuit Diagram
For example, mosquito repellent creams and oils can cause unfavorable effects on the skin like hypersensitive responses. Likewise, coils, sprays, and mats can create poisonous exhaust when heated and cause breathing difficulty. In this regard, and electronic mosquito repellent is fascinating and safe for human health. How the Circuit Works. In our proposed electronic mosquito repellent circuit we have used a CMOS integrated circuit as an oscillator. This has the advantage of very low power consumption, an important quality for a portable device. The output of the oscillator drives a pair of parallel triggers, effectively doubling the current capacity.
