Attention: Temperature and humidity plays an important role for the saving of books.

Gorky once said that books are the ladder of human progress. Leo Tolstoy said Ideal Books Are Key To Wisdom. Books play an important role in our life. The public library as an important part of the public culture service system has a responsibility for saving human culture human cultural heritage, holding social education, spreading public knowledge & information, and developing intellectual resources.

The facilities of the national public library have been improved continuously, public cultural products have become more abundant, service capabilities have been improved, and social benefits have increased significantly. In 2019, there were 3,196 public libraries nationwide, an increase of 20 from the end of the previous year; the total book collection was 11.178 million, an increase of 7.3% over the end of the previous year; 865.57 million e-books, an increase of 7.0%; the number of reading room seats was 1,190,700, An increase of 6.6% over the end of the previous year.

The book is stict with temperature, humidity, light intensity and other elements of library. More higher temperature, more fast chemical reaction rate and longer time of paper folding strength retention. Lower temperature, slowy chemical reaction rate and shorty time of paper folding strength retention. Usually, every time the temperature decreases or increases by 20℃, the life of the paper will increase or shorten by more than 7-8 times. Paper is a kind of hygroscopic substance. It not only ages under the influence of temperature, but also easily deteriorates under the influence of humidity. At the same time, when the humidity is high, the book paper is also prone to mold and insects, which makes the book paper fragmented and even adhered into "bricks".

It can be seen that the influence of temperature and humidity on books is very large. As a place for data storage, the library is the most important place to monitor temperature and humidity. It is a product for real-time monitoring of environmental data information such as temperature and humidity in the library. It is a "good helper" of the library. HENGKO, as a local temperature and humidity IoT solution provider with more than ten years of experience in Shenzhen, has always introduced new ideas and made continuous breakthroughs in the field of temperature and humidity measurement. We have hundreds of different temperature and humidity product: handheld dew point meter, dew point transmitter, temperature and humidity transmitter, RS485 integrated temperature and humidity transmitter, portable temperature and humidity data logger, temperature and humidity probe, temperature and humidity controller, handheld soil temperature and humidity probe and so on.

If you want to monitor the temperature and humidity in the library, you can collect temperature and humidity in multiple areas in the library, such as connecting multiple temperature and humidity transmitters or thermometers and hygrometers, and the collected data can be directly transmitted to the PC in RS485 mode. For display, data storage and analysis, it can be integrated with various environmental monitoring systems to realize remote control. HENGKO temperature and humidity transmitter series products specially designed for temperature and humidity monitoring in harsh environments, with a wide range of applications including indoor environments, HVAC, livestock farms, greenhouses and various outdoor application. We have professional technology team provide humidity sensor IOT solution for your measuring demand.
