The invention relates to a VOC sensing network monitor, and belongs to the technical field of atmospheric environment monitoring. The monitor comprises a shell provided with an air inlet and an air outlet, a main control panel installed in the shell and an installation plate provided with an information acquisition system which is electrically connected with the main control panel, the shell is internally provided with a power system and an information transfer system, the information acquisition system comprises a sensor group fixed on the installation plate, the sensor group comprises a temperature sensor, a humidity sensor, a PID sensor and a CMOS sensor, an air circulation hole is formed between the installation plate and the inner wall of the shell, the air inlet, the air circulation hole and the air outlet form an air circulation channel allowing air to pass through the sensor group, and a positioning device is arranged in the shell. The monitor adopts the sensors to acquire pollutant information, the making cost and maintenance cost of the monitor are reduced, grid setting can be conducted in large quantities, information is fed back in real time, and the monitoring information is more accurate.
