Electronic mosquito repellent using 555 timer circuit
This electronic mosquito repellent electronic project is based on the 555 timer circuit. This electronic mosquito repellent circuit generate an ultrasonic sound with a high output frequency that allows spreading mosquitoes within a wide radius . The circuit is quite ...
Description. Here is the circuit diagram of an ultrasonic mosquito repeller.The circuit is based on the theory that insects like mosquito can be repelled by using sound frequencies in the ultrasonic (above 20KHz) range.The circuit is nothing but a PLL IC CMOS 4047 wired as an oscillator working at 22KHz.A complementary symmetry amplifier consisting of
And Dog Repellent The electronic dog repellent circuit diagram below is a high output ultrasonic transmitter which is primarily intended to act as a dog and repeller, which can be used individuals to act as a deterrent against some animals. It should NOT be ...
This circuit is built to repel mosquito using high frequency sound. The design is comprised of LM555 timer which provides the pulse generation and precision timing. It is also a stable controller capable of monostable or astable operation. The 74HCT4017BQ device is a Johnson decade counter with 1...
Low cost Ultrasonic Pest Repeller-2: The circuit in Figure 2 is a pest repeller described in the French electronics magazine, "Le Haw Parleur". In the article, the author claims that frequencies in the range of 20 to 40 kHz cause highly uncomfortable cavities to form in brain fluids and blood vessels of mice and insects, causing them to beat a hasty retreat.

Electronic Mosquito repellent Types and Circuit Operation
A multivibrator is an electronic circuit which is used to generate a pulsed output signal. Usually, multivibrators are classified into different types based on the stability of the output. Here the common form of a stable multivibrator is 555 Timer IC, which is used in this electronic mosquito repellent circuit, and it consists of 8 pins.
To use this circuit adjust R3 at resonance frequency of the piezo transducer for maximum amplitude of the repeller ultrasonic sound. At 30 KHz this can reach a value of 108 Vpp. Without the piezo the output voltage is around 200 Vpp. Note: Component:
