The application of temperature sensor field
one, in the museum of cultural relics, archives management, use the
this is another area where temperature and humidity sensor applications. Archives of paper in the appropriate temperature and humidity conditions can store some more time, and once the temperature and humidity conditions being destroyed paper is going to become fragile, important information will be gone, for temperature and humidity records of archives is necessary, can prevent the happening of the malignant accident. Use will lead to work to simplify the temperature and humidity records of temperature and humidity, also will save the cost of the cultural relics preservation, enables the work to the scientific, not too many human factors of disturbance.
2, in the use of the vaccine cold chain
in the vaccine, vaccine and other biological products from pharmaceutical factory finished product warehouse shipments, to give people get cold chain storage and transportation process, through to its environment temperature monitoring records, can confirm the quality, ensure the immunization effect. Temperature and humidity sensor is convenient and reliable way to solve the problem.
different vaccines and vaccine for storage and transportation environment temperature have different requirements. To ensure the safety of the bacteria, vaccine in the process of storage and transportation process must be conducted on the environmental temperature of storage and transportation process inspection records, and should be fully automated testing record, should not have any man-made factors, in order to improve the reliability of data. High quality and high precision of temperature and humidity sensor can perfect finish this function, because it can be in the absence of external power supply can also record for a long time.
3, in the field of building materials experiments using the
in the process of building materials, especially the concrete dry, we should pay attention to its drying trend, this is one of the evaluation index of the product, also provide reliable data for the construction of the building. Application of temperature and humidity sensor can record the data and provide building materials research, will provide beneficial help for the construction. Especially in military architecture, time is life, accurately grasp the enemy, the concrete dry time first to effectively provide effective force to provide the guarantee on the battlefield, this function can be performed by temperature and humidity sensor.
4, used in the agriculture and animal husbandry
agricultural and livestock production, especially some economic crop production, in the seedling stage to record temperature and humidity value in detail. Such as to determine some seedlings growth characteristics have what kind of relationship with temperature, humidity, etc. , it also need to temperature and humidity sensors for data acquisition and hard. There are, of course, not every young plants need to be temperature monitoring, forestry, after all, is a relatively thick line production mode.
5, use in food storage and transportation,
due to the time of storage and transportation of food is not a short-term problem, but the relative equilibrium moisture in food preservation is to ensure food safety is an important indicator of relative balance humidity affects the growth of colonies. Aimed at this situation, the use of real-time monitoring of temperature and humidity, temperature and humidity change to ensure food safety into the consumer's mouth.
when long-distance transportation or Marine refrigerated food, how to prove in the receiving of the goods has been at the specified temperature and humidity conditions is a very important thing. Approach is to settle the dispute at the time of delivery in the cargo hold a temperature and humidity sensor, and start it, it will faithfully record the whole transportation process, temperature and humidity changes, the shipper will know immediately if there is a responsibility. Now a lot of famous fast food enterprises in the use of temperature and humidity sensor.
