NE 555 timer
IC Diode (1N4007)
Piezo Buzzer
Working of bug repellent circuit
Here the 555 timer is configured in astable multivibrator mode, specifically devised for generating sound at the ultra frequency levels.
The frequency of this circuit is set to 25 kHz, this frequency falls in the ultrasound region and it is not audible to human beings.
The 1N4007 diode is used to get 50% duty cycle for the frequency generator.
The piezo buzzer converts the output of 555 astable to ultrasonic sound that can be heard by the insects.
This ultrasound frequency cause some irritations and uneasiness to the insects such as mosquitoes. However it will not disturb you if you have installed this circuit of insect repellent for your home.
How to Design a mosquito repeller circuit
We need 25 kHz signal, so the time period will be 40µseconds.
Then Ton=Toff=20µSeconds.
