Our micro-monitor can be mounted on the roof of a vehicle to accurately monitor the concentrations of various typical atmospheric pollutants,including TVOC, NO_x, CO, PM_2.5, SO₂, and CO₂, in the form of mobile monitoring with high temporal resolution (fastest 5 seconds). This enables the creation of pollution maps within the region, dynamically presents information on unorganized emissions from enterprises, promptly identifies potential environmental and safety hazards, and timely assesses and predicts potential corporate pollution complaints. It rapidly identifies regional ambient air pollution, grasping characteristics, pollution factors, pollution distribution, concentration levels, and spatio-temporal changes of regional ambient air pollution. This provides targeted monitoring and precise supervision for the treatment and continuous improvement of regional ambient air pollution, and offers decision-making support for comprehensive management and control of regional ambient air pollution.
