Description

Electromagnetic wave alarm

The present invention relates to an electromagnetic wave alarm, and more specifically, an electric field and a magnetic field are independently detected, and harmful waves having a predetermined intensity range are separately detected from a high frequency band and a magnetic field of a predetermined high frequency band. It relates to an electromagnetic wave alarm consisting of display means formed to be displayed independently of each other.

In general, an electromagnetic wave is a wave phenomenon in which vibrations caused by periodic changes of electricity and magnetism propagate through space or matter, which is a kind of energy flow.

At this time, the space region exerted by the force of electricity is called the electric field, and the space region exerts the force of the force is called the magnetic field.

The electric field inevitably induces a magnetic field, and the magnetic field induces an electric field. In reality, the electric field and the magnetic field mutually influence each other and are inseparably coupled to propagate in space and are called electromagnetic waves.

Here, the electric field is easily shielded by all conductive objects, but the magnetic field is easily passed through almost all objects, and it is judged that the effect of the magnetic field is greater than that of the electric field.

The effect of electromagnetic waves on the living body is not significantly different from the meaning of having a harmful effect on the living body, which corresponds to a known fact.

On the other hand, the electromagnetic wave is a wave phenomenon, the frequency is an essential element, and is classified into ultra low frequency, ultra low frequency, radio wave, and microwave according to the frequency band.

Electromagnetic waves in the ultra low frequency, ultra low frequency, and radio wave ranges are used as the criteria for harmfulness by measuring electric fields and magnetic fields, and microwaves are used as criteria for harmfulness by measuring power per unit area.

In addition, each country is making efforts to enact the establishment of facilities to block electromagnetic waves by recognizing the harmfulness of electromagnetic waves according to the above criteria, which is also necessary for Korea to block electromagnetic waves under Article 24 of the Industrial Safety and Health Act. The same can be said in that it is legalized.

The harmfulness of electromagnetic waves not only affects living organisms but also precision electronic devices, which may cause malfunction of devices. Therefore, there is a need to prevent harmful effects by recognizing and blocking them in advance.

However, since electromagnetic waves are difficult to be easily recognized due to their propagation characteristics through space or matter, a separate detection device is required to detect electromagnetic waves.

Herein, a method or apparatus for detecting an electromagnetic wave belongs to a known fact, but conventional electromagnetic wave detection apparatuses for this purpose are those which can be used only by a person who has an electromagnetic wave measured at the same time and has some knowledge of electromagnetic waves.

In other words, ordinary people without general knowledge of electromagnetic waves are difficult to recognize whether the intensity is harmful even if the existing electromagnetic wave detection device recognizes the existence of electromagnetic waves, and has the ability to identify which physical elements are harmful by measuring electric and magnetic fields at the same time. There is also a problem that is difficult.

In addition, there is a problem that requires a separate operation for electromagnetic wave measurement.

The present invention has been devised to solve the above problems, the electric field and the magnetic field is independently detected, the high frequency of the high frequency band of the electric field and the harmful wave of the predetermined intensity range harmful to the human body of the magnetic field is separately detected, and It is an object of the present invention to provide an electromagnetic wave alarm so that the general public can easily recognize the presence of electromagnetic waves and whether they are harmful by simply placing the magnetic field, high frequency, and harmful waves in the room.
