AI Technical Summary

Problems solved by technology

An important defect of these temperature and humidity measurement and display methods for the site environment is that only real-time temperature and humidity data observation can be performed on site. There is no way to remotely collect the temperature and humidity data of the site under test, and there is no temperature and humidity data record. , there is no way to query and analyze the past temperature and humidity data; use a dot-type paper temperature and humidity data recording printer to record temperature and humidity data. An important defect of this temperature and humidity recording device is also that there is no way to remotely monitor the measured site. The temperature and humidity data are collected, and the temperature and humidity record data can only be expressed on paper in the form of waveform diagrams. There is no way to digitize them electronically. The query and analysis of temperature and humidity data can only be carried out by manual reading. Yes, measurement data sharing is difficult with this approach
