Artifacts in museums , archives management application
This is the temperature and humidity sensor applications is another area . Paper files in the appropriate conditions of temperature and humidity can store some more time , and once the temperature and humidity conditions, the paper will be brittle destruction , important information will subsequently gone, the archives of temperature and humidity recording is necessary, can prevent accidents from happening. Using the temperature and humidity Engine Water Temperature Sensor temperature and humidity recording work will be simplified and will also save the cost of cultural relics preservation , to make this work to be scientific, not subjected to excessive anthropogenic disturbances .
