Temperature and humidity sensor
Temperature: The physical quantity that measures the hot and cold of an object is one of the seven basic physical quantities in the International System of Units . In production and scientific research, many physical phenomena and chemical processes are carried out at a certain temperature, and people's lives are closely related to him. 　　
   Humidity: There is a close relationship with life before the humidity is long , but it is more difficult to express it by quantity. The means of humidity are absolute humidity, relative humidity, dew point, moisture to dry gas ratio (weight or volume), and the like. The most commonly used physical quantity for expressing humidity in daily life is the relative humidity of the air. Expressed in %RH . Relative humidity has a close relationship with temperature in the derivation of physical quantities. A certain volume of closed gas, the higher the temperature, the lower the relative humidity, and the lower the temperature, the higher the relative humidity. Temperature and humidity sensors involve complex thermal engineering knowledge. 　　
   Some definitions about humidity: 　　
   Relative Humidity: In the metrology method, humidity is defined as the “ amount of object state †. The moderation referred to in daily life is relative humidity, expressed as RH% . In short, the percentage of the amount of water vapor (water vapor pressure) in a gas (usually in air) and the amount of saturated water vapor (saturated water vapor pressure) in the same condition as air. Welcome to the company's official website http://
   Absolute humidity: refers to the amount of water vapor actually contained in the air per unit volume, usually in grams. Temperature has a direct effect on absolute humidity. Under normal circumstances, the higher the temperature, the more water vapor is emitted, and the greater the absolute humidity; on the contrary, the absolute humidity is small. 　
Saturated humidity: The maximum amount of water vapor that can be contained in the air per unit volume at a certain temperature. If this limit is exceeded, excess water vapor will condense and become water droplets. At this time, the humidity of the air becomes called saturated humidity. The saturated humidity of the air is not fixed and it changes with temperature. The higher the temperature, the more water vapor can be contained in a unit volume of air, and the greater the saturation humidity. 　
   Dew point: refers to air containing a certain amount of water vapor (absolute humidity). When the temperature drops to a certain level, the water vapor will reach saturation (saturated humidity) and begin to liquefy into water. This phenomenon is called condensation. The temperature at which water vapor begins to liquefy into water is called " dew point temperature " and is referred to as " dew point " . If the temperature continues to drop below the dew point, the supersaturated water vapor in the air will condense into water droplets on the surface of the object. In addition, the wind is closely related to the temperature and humidity in the air, and is also one of the important factors affecting the temperature and humidity changes of the air.
It is enough to look at these points when purchasing a detachable Container House!
There are still many types of detachable container house on the market, and in addition to being used on daily construction sites, many temporary buildings such as apartments, homestays, offices, schools, dormitories, and camps are also widely used. Its construction is convenient, the investment is low, and it can be used for a long time, and the cost performance is also really good. But there are many similar container houses on the market, how should we choose? In fact, it is enough to look at the following points when purchasing a high-quality container house.
Green is very important
The structure of the container house is simple, and it can also be disassembled. Even if it is only used for a short time, it can be installed again later, which will not cause waste of materials and will not generate construction waste. And you can freely splicing and DIY to create a lot of shapes, which is very good. It is an incomparable advantage of Folding Container House and Flat Pack Container House. When choosing a detachable container house, the roof can be made of solar panel materials, so that It can provide enough electric energy for the interior of the house, and can also achieve a good environmental protection effect.
Ease of use comparison
Compared with traditional concrete buildings, the construction of detachable container houses is really convenient. You only need to determine the specific dimensions and specifications, and then you can install them immediately. Moreover, the panels only need to be assembled in order. If it is a small container house, one or two workers can quickly complete the construction. Moreover, the boards of container houses are easy to transport. Even if the house has been built, it can be disassembled and transported directly in the later stage, and it is very convenient to use in different positions.
Cost-effective comparison
Since it is necessary to purchase a detachable container house, it is still necessary to measure the price. On the one hand, it is necessary to determine the quality of its materials and whether it can meet the standard of long-term use. On the other hand, it is also necessary to measure the price. Generally, manufacturers quote according to the specific size and area of the container house and the material of the color steel plate, so it is still necessary to make a comprehensive comparison, so that it is also very simple to choose a cost-effective container house.
