The invention discloses an environment monitoring device based on electricity poles. The environment monitoring device is characterized in that the environment monitoring device comprises a plurality of monitoring circuits arranged on a plurality of electricity poles respectively, and a first server in wireless connection with the plurality of monitoring circuits. Each monitoring circuit comprises a soil sensor arranged at the bottom portion of each electricity pole and used for collecting a soil quality signal, an air quality sensor arranged on the upper portion of each electricity pole and used for collecting an air quality signal, a power generation module arranged on the upper portion of each electricity pole and used for generating power, a wireless module arranged on the upper portion of each electricity pole and used for sending the data, and a microcontroller connected with the soil sensor, the air quality sensor, the power generation module and the wireless module, wherein the microcontroller receives the soil quality signal and the air quality signal and sends the soil quality signal and the air quality signal to the first server through the wireless module. The electricity poles are generally arranged around a factory, and thus the collected information is more accurate.
