Electronic mosquito repellent circuit diagram

After introducing the electronic mosquito repellent circuit, this time we will continue to introduce an equally interesting electronic circuit, that is, the electronic mosquito repellent circuit.

In fact, electronic mosquito repellers and mouse repellers work in exactly the same way, using echolocation, which neither animal likes. As we all know, both of these animals are very distracting when they are in our homes.

This electronic mouse repeller circuit is very simple as it uses only a few different types of components. So for those of you who are currently studying or learning electronics, you can try to practice making this circuit as it is relatively easy for beginners.

There is very little information about the components needed to build this circuit, which is less than 10 components. Therefore, it is estimated that the price of this series needs to be less than $5. It is very suitable for beginners who want to practice making electronic circuits.

The components required are basic components like resistors, capacitors, transistors, IC 555, and output in the form of a speaker. So this is a speaker that can emit 50 Hz scanning echolocation. The sound is the sound of annoying mice, and mice dare not come near.

You don't need to worry because these sounds will not disturb your sleep. This sound will be loud in the ears of mice, but not in human ears.
