The development trend of humidity sensors
The characteristics of the humidity sensor are introduced . The performance characteristics and product classification of the integrated humidity sensor and the single-chip intelligent humidity / temperature sensor are emphasized. Finally, the technical indicators of the integrated humidity sensor are given. 　　
   In industrial and agricultural production, meteorology, environmental protection, national defense, scientific research, aerospace and other departments, it is often necessary to measure and control the environmental humidity. However, in conventional environmental parameters, humidity is one of the most difficult parameters to measure accurately. The method of measuring humidity with a wet and dry bulb hygrometer or a hair hygrometer has long been unable to meet the needs of modern technological development. This is because measuring humidity is much more complicated than measuring temperature, temperature is measured independently, and humidity is affected by other factors (atmospheric pressure, temperature). In addition, the standard of humidity is also a problem. The humidity calibration equipment produced abroad is very expensive. Welcome to the company's official website http://
   In recent years, great progress has been made in the field of humidity sensor research and development at home and abroad. Humidity sensors are rapidly evolving from simple humidity sensors to integrated, intelligent and multi-parameter detection, creating favorable conditions for the development of a new generation of humidity / temperature measurement and control systems, and raising humidity measurement technology to a new level.
Metal silicon, also known as Crystalline Silicon or Industrial Silicon, is mainly used as an additive to non-ferrous based alloys. Metal silicon is a product made of quartz and coke in an electric furnace. The content of silicon in the main component is about 98% (in recent years, 99.99% of Si is also contained in metal silicon), and the remaining impurities are iron and aluminum. , calcium, etc.
