Electronic mosquito repellent

Electronic mosquito repellent

 

 

 

  This is a simple circuit to execute in your home and here youwill take an over view about the circuit , how it's work , the components 

This circuit or project can help you by keeping the mosquito and similar other insects and creatures away from you using a high frequency sound produced by this circuit

 

 

Then main principle in which this electronic mosquito repellent works is that mosquito and insects are highly sensitive to some frequency of sound and they don’t like the sound. And insects and mosquito will leave or get away from you due to the annoying sound. But the sound it produces is of high frequency which cannot be heard by humans so you will not be affected by the sound

 

In the circuit timer IC 555 is used as an oscillator it generates frequency of 200 HZ to 62 KHz, The working frequency of the circuit can be set by rotating preset resistor (R2), and the speaker converts the electronic frequency to sound frequency

Try to keep the frequency of the sound as high as possible. And make sure you don’t hear the sound of this circuit by keeping it above 20 KHZ, The annoying sound will be heard by insects but not by you because humans don’t normally hear sound of frequency higher than 20 KHz

This circuit requires an input voltage of around 5 V, you can also use input voltage of up to 9 V

And please use a speaker of good quality in the circuit, using good quality speaker will ensure that the project will work
