The invention relates to the field of environmental monitoring, in particular to an organic waste gas monitoring device based on the Internet of Things. The device comprises a support rod, a support mechanism, a monitoring mechanism, a pressurizing mechanism, a water storage mechanism, a dust removal mechanism and a solar cell panel, wherein a water storage mechanism for storing water in rainy days is mounted at the edge of the top of the supporting mechanism; after the water amount in the water storage mechanism reaches a certain amount, the water is poured out, so the dust removal mechanismis pulled; after the dust removal mechanism is pulled, dust removal of the solar cell panel is realized, heat absorption of solar energy is facilitated, continuous power supply to the monitoring mechanism is realized, and environment detection is facilitated; the top of the monitoring mechanism is rotationally connected with a pressurizing mechanism; when water in the water storage mechanism is poured out, the pressurization mechanism on the top of the monitoring mechanism is pressed, so the pressurization mechanism promotes air circulation of the monitoring mechanism, the rainwater is prevented from making contact with the monitoring mechanism, the air circulation is promoted, and the situation that the monitoring effect is affected by rainwater flowing is avoided.
