The so-called dew point, the lower the temperature of the dew point sensor picture, the smaller the saturated water pressure. Therefore, for air containing a certain amount of water vapor, the temperature is lowered while the air pressure is constant, and the saturated water vapor pressure is reduced to a temperature equal to the actual water vapor pressure at that time, which is called a dew point. Supplement: When the temperature is below zero degrees Celsius, it is also called frost point. From this we can not see the dew point and pressure, the temperature has a close relationship. The amount of water in a variety of traits often affects the performance, use, quality and storage of the substance. For example, the water content of the process gas will affect the electrical insulation properties and process state of the product; the moisture content of the power gas will affect the service life of pneumatic instruments and equipment. The reason is mainly that H2O is an extremely active substance, which is easy to chemically react with other substances, and is also easily decomposed into oxidizing substances. We usually refer to the water content in the ambient atmosphere as relative humidity. The moisture content of industrial gases is expressed by the dew point temperature or PPm value. The dew point analyzer is simply a dew point meter, which is an instrument used to measure the moisture content of a gas.
What is Battery Mini Camera
Micro camera is a product of modern high-tech, also known as micro monitor. It has the characteristics of small size, powerful function and good concealment.
Some cameras also use video transmission lines for synchronous power supply without external power lines.

Wireless
Wireless equipment is used stably in domestic wireless environment. The micro wireless surveillance camera has the characteristics of high stability, high speed, long distance and multi-point testing. It can play a huge role in the fields of environment, energy, construction, transportation, medical treatment, industrial machine condition monitoring, etc., especially when the cabling is complex, the cabling cost is high, the long-distance and large-scale transmission of data and the mobility demand is high. Secret Video camera
The main structures and components of the camera can be listed from the working principle of the camera:
1. LENS
Lens structure, consisting of several lenses, including plastic lens or glass lens
2. Image sensor
It can be divided into two categories:
CCD (charge couple device): charge coupled device
CMOS (complementary metal oxide semiconductor): complementary metal oxide semiconductor
3. Digital signal processing chip (DSP)
There are many DSP manufacturers, such as VIMICRO 301P/L, SONIX 102/120/128, ST (Logitech LOGITECH's DSP provider), SUNPLUS (SUN+focuses on the development of CIF and VGA for single chip, but the image quality is average), PIXART (original phase), PAC207, SQ930C, etc.
4. Power supply
Two working voltages are required inside the camera: 3.3V and 2.5V. The latest process chip can use 1.8V.
The role of the dew point meter
The so-called dew point, the lower the temperature of the dew point sensor picture, the smaller the saturated water pressure. Therefore, for air containing a certain amount of water vapor, the temperature is lowered while the air pressure is constant, and the saturated water vapor pressure is reduced to a temperature equal to the actual water vapor pressure at that time, which is called a dew point. Supplement: When the temperature is below zero degrees Celsius, it is also called frost point. From this we can not see the dew point and pressure, the temperature has a close relationship.
