when the monitoring device is required to work, the small air pump 32 is controlled to work regularly through the PLC, when the small air pump 32 works, the small air pump 32 discharges the gas stored in the plurality of monitoring boxes 1 through the exhaust pipe 31, so that the air pressure in the monitoring boxes 1 is reduced, the external gas enters the monitoring boxes 1 along the air inlet pipe 2 under the pressure of the air pressure, the gas to be measured in the area to be measured is conveyed into the solution in the monitoring boxes 1 through the short pipe 4, when the leaked sulfur dioxide exists in the area to be measured, the sulfur dioxide reacts with the water in the monitoring boxes 1, the sulfur dioxide reacts with the water, so that white precipitates such as sulfurous acid and sulfuric acid are generated, and when nitric acid gas exists in the air, yellow-green precipitate is generated in silver ion solution, when the small air pump 32 works, the small air pump 32 discharges the gas into the exhaust box 331, part of the gas is discharged from the gas outlet 34, part of the gas is conveyed into the trigger cylinder 332 along the micro-pore plate 35,

photoelectric component 30 generates light energy, the photoelectric component 30 and the light emitting diode are similar, the core is also a p-n junction, when light waves with photon energy larger than the forbidden band width of the p-n junction semiconductor material are irradiated, the valence electrons in each region of the p-n junction absorb photon energy and break loose into free electrons, a hole is generated, the free electrons and holes generated by the illumination are called photo-generated carriers, the photo-generated free electrons and holes in the depletion layer move to the n area and the p area respectively at a high speed under the action of the electric field force and reach the electrodes to move along an external circuit to form photocurrent, and in the same way, after the white filter 29 detects the white precipitate, the photocurrent is generated, after the filter 29 in the monitoring box 1 generates the photocurrent, the filter 29 is electrically connected with the micro air pump 42 through the PLC controller, after the filter 29 generates the photocurrent, the micro air pump 42 is firstly controlled by the PLC controller to start to work for a period of time, and when the sulfur dioxide or nitric acid gas in the area to be detected leaks seriously, the generated white precipitate or yellow-green precipitate has a deeper color, so that the stronger the generated photocurrent is transmitted to the micro air pump 42 by the PLC controller, the more the micro air pump 42 delivers the gas into the vertical cylinder 41 in unit time, the higher the position of the sealing block 44 and the conducting frame 45 moving upwards, the conducting frame 45 is electrically connected with an external power supply, the conducting blocks 46 are
