Therefore, a power source, for example, a DC power source, generated from the body 100 may be applied to the second electrode units 312 and 312 '.

In the apparatus for detecting harmful substances of the present invention 10, the harmful gas detecting unit 300 is disposed on both sides of the through hole 110 formed in the body 100, .

2, the body 100 includes a power supply module 110, a first electrical resistance measurement module 120, a second electrical resistance measurement module 130, a storage module 140, A wireless communication module 150, a GPS module 170, and a wireless communication module 160.

In general, the first electrode units 212 and 212 'disposed in the water may have a constant electrical resistance value. That is, the amount of change with respect to the electric resistance value may be extremely small or may not occur.

However, because harmful substances are composed of a component having many acid-based ions, electricity can be more easily transmitted through the first electrode units 212 and 212 '.

6, the higher the concentration of the harmful substance HNS contained in the water 3 is, the lower the electrical resistance value of the first electrode units 212 and 212 ' It is possible to detect the harmful substances contained in the water 3 based on the changed electrical resistance value.

As a result, the amount of electrons is reduced, so that the electric resistance value of the second electrode units 312 and 312 'increases as shown in FIG.

Since the reducing gas reacts with the electrons on the surfaces of the electrode units 312 and 312 'and moves to the center as opposed to the oxidizing gas, the electric resistance value of the second electrode units 312 and 312' .

Therefore, as shown in FIG. 7, as the concentration of the reducing gas increases, the electric resistance value of the electrode portions 312 and 312 'decreases
