Description

Technical field: [0001] The present invention relates to a method and device for measuring environmental parameters, in particular to a method and device for measuring environmental temperature and humidity dew point. Management and analysis functions. Background technique: [0002] There are many kinds of instruments for measuring environmental parameters such as temperature and humidity, but they have some problems in various aspects such as measurement accuracy, function, design, etc., which limit their use: [0003] 1. Only one or two parameters such as temperature and humidity can be measured separately, and the dew point information cannot be accurately calculated, and the measurement accuracy is not high; [0004] 2. The sensors used are installed fixedly, are not easy to replace, have poor consistency, narrow measuring range, and short effective service life; [0005] 3. The function is single, with only simple collection and display functions; [0006] 4. There i...

Problems solved by technology

[0002] There are many kinds of instruments for measuring environmental parameters such as temperature and humidity, but they have some problems in various aspects such as measurement accuracy, function, design, etc., which limit their use:

[0003] 1. Only one or two parameters such as temperature and humidity can be measured separately, and the dew point information cannot be accurately calculated, and the measurement accuracy is not high;

[0004] 2. The sensors used are installed fixedly, are not easy to replace, have poor consistency, narrow measuring range, and short effective service life;

[0005] 3. The function is single, with only simple collection and display functions;

[0006] 4. There is no alarm, voice prompt and other functions for the measured data;

[0007] 5. There is no storage function for the measured data, or the storage capacity is small, it can only be collected and displayed, and the data cannot be stored for research;

[0008] 6. Communication with the upper computer cannot be realized, there is no supporting auxiliary analysis software for the upper computer, and the ability to manage data is poor;

[0009] 7. In terms of power supply processing, the battery usage efficiency is relatively low, and the working time of the battery cannot be fully extended. At the same time, the power consumption is large during work measurement, and the unused functions cannot be turned off in time;

[0010] 8. Some environmental parameter measuring instruments with relatively complete functions, multi-parameter measurement and high precision are mostly imported from foreign countries, which are expensive and costly, which is not conducive to promotion
