Precision agriculture is a key development direction of modern agriculture. A significant feature of precision agriculture is the use of big data in agriculture, such as agrometeorological data, and the major sources of access to these big data are agricultural environmental monitoring stations and other agricultural instruments. Or the Internet of Things system, using agricultural environmental monitoring stations to collect real-time agricultural data such as agricultural climate, soil and air quality, crop maturity, and predictive analysis, can help agricultural workers make more informed decisions and improve agriculture. The level of refinement and management will promote the improvement of agricultural production efficiency. Agricultural meteorology has always been one of the most important factors affecting agricultural production efficiency. Therefore, with the development of science and technology, to realize the goal of precision agriculture, it is necessary to increase understanding of agricultural meteorology and use agricultural environmental monitoring stations to treat air. The collection and monitoring of data such as temperature, air humidity, soil temperature, soil moisture, light, rainfall, etc., is one of the foundations for the development of precision agriculture. It uses the collected large data of the agricultural environment for analysis and research, and then carries out agricultural related models. Analytical calculations can help agricultural workers make the most wise decision on crops in terms of nursery, planting, fertilizing and harvesting, and optimize production processes. This is the smallest cost investment and maximizes the benefits of agricultural production. The specific impacts of agricultural environmental monitoring stations on the development of precision agriculture are mainly reflected in several aspects. For example, the use of agricultural environmental monitoring stations to monitor the agricultural environment has increased the level of understanding of farmers' friends on the crop's growing environment. The development of agricultural activities provides the basis for the fertility of farmland soil. How is soil moisture? How is the temperature and humidity of the air? We can all see that through these data, farmers’ friends will know when crops need fertilization, when irrigation is needed, and more precise arrangements are made for irrigation, fertilization, spraying, etc., so as to effectively save water and fertilizer inputs and effectively prevent pests and diseases. Occurs and achieves significant cost savings and increases in production and income. Low-temperature 2-color Ratio Pyrometer
This classification includes two color infrared pyrometers measuring range is 250℃-2200℃.
Compared with one color infrared pyroemter, two color pyrometer measuring result will not change with state of object surface (surface roughness or surface chemical state), that means two color infrared thermometer accuracy will not be affacted, while the 1-color pyrometer will.
Products in this classification are usually applied to metallurgical industry(rod and wire mills, Hot rolling mills), foundry, cement kiln, induction heating, heat treatment, heating furnace, vacuum furnace, monocrystalline silicon, polysilicon, semiconductor and other industrial temperature measurement.

The optical part of pyrometer, such as glass, will accumulate some dust in the surfac after using for a period. Water, gas, oil vapour, dust in the air will reduce the emissivity coefficient, so the monochromatic pyrometer will reduce the measured value at this time. The Dual color pyrometer measures the ratio of infrared radiation intensities of two band wavelength in a specific range. With dust, water vapor and other disturbances, the signals of two wavelength fall simultaneously and the ratio remains constant after division. And user just need to wipe the glass when it is too dirty.
Monochromatic thermometers cannot measure objects smaller than the field of view. When the object does not fill the field of view, the measurement temperature will be low. A bicolor pyrometer can measure objects smaller than the field of view.
