Introduction
Mosquitoes are a danger to any being. This tiny insect can affect several human beings. We have seen so many viruses like dengue, etc and so many diseases like malaria, etc. These tiny mosquitoes have spread this all. However, this era is the era of cure. And, we human knows how to find solutions to problems. Therefore, an electronic mosquito repeller got invented. So, in this tutorial, we will discover how to make a Mosquito Repellent Circuit. This device is for people to prevent them from biting mosquitoes.
Many of us are aware of creams, etc that repel mosquitoes. But, very few know those things can be toxic to the human body. However, an electronic mosquito repeller is comparatively efficient, especially for heated areas and humid climatic regions. It gives ultrasound waves by the speaker present in the circuit. As a result, insects get irritated by those sounds. And, this helps in repelling mosquitoes.

Mosquito Repellent Circuit
Working Explanation
The insects and small species can hear the ultrasonic noise, which is above 20KHz. So, we need to generate ultrasonic sound. Therefore, in this Mosquito Repellent Circuit, we have used NE555 timer IC that produces a square wave at the output. 10k potentiometer is there to adjust the oscillation frequency of the astable multivibrator. Hence when you power the circuit, it would help to repel the mosquitoes in that area.
Applications
- Usually used to repel tiny insects such as mosquitos & flies.
- Hence, everywhere where the mosquitoes are
- With some modification, we can use it as an insect repeller
