Problems solved by technology

However, the existing air micro-station has the following disadvantages: the micro-air quality monitoring station uses electrochemical sensors to monitor toxic and harmful gases in the air station, the cost is low but there are many interference factors, and the temperature drift of the electrochemical sensor interferes with the detected gas. There is a zero current, ambient temperature and humidity that will cause great interference to chemical sensors, and the most typical one is SO 2 , NO 2 , O 3 cross interference between
