The small weather station is a special equipment for the Bureau of Agriculture, Chinese Academy of Sciences, soil and fertilizer stations, and colleges and universities. It is also widely used in meteorology and agriculture to detect the impact of meteorological changes on crops, scientifically manage farmland cultivation, and implement standard fertile land and water-saving irrigation projects. Therefore, it can be said that small weather stations are very important devices in modern agricultural production. With the rapid development of agriculture, the use of small weather stations has gradually increased. Many regions or units have the need to purchase small weather stations. Therefore, let's introduce the following points: 1. Acquisition parameters The first point of purchasing a small weather station is to pay attention to the acquisition parameters of the instrument. The small weather station can have the wind speed, wind direction, rainfall, air temperature, air humidity, light intensity, soil temperature, soil moisture, and evaporation. More than a dozen meteorological elements, such as atmospheric pressure, are monitored at all times in the field. However, the commonly used monitoring parameters are mainly wind speed, wind direction, temperature, humidity, light, rainfall, etc. Therefore, the user can select suitable parameter elements to purchase according to actual needs. 2. Power supply mode The power supply mode of the small weather station is also an important point to pay attention to during the purchase process. In general, the power supply mode of the small weather station mainly includes AC220V, solar power supply system, storage batteries, and dry batteries. The field power supply system is not perfect. In regions where electricity supply 220V and other power supply facilities are available, solar power supply systems and battery power supply and dry battery power supply can be used. 3. Communication method The last one to purchase a small-scale weather station is the communication method. Currently, the communication methods adopted by the small-scale weather station mainly include wired: RS485/USB and wireless: GPRS/433/zigbee. The user can select the suitable one according to his own use area. Your own communication method is currently the most popular method of wireless communication. In addition, because small weather stations are mostly used for field weather monitoring, in order to improve the protection of the equipment, according to actual needs, in the selection of small weather stations can also consider the field set, such as protective boxes, brackets and so on.
Tung oil was used as a preservative for wood ships. The oil penetrates the wood, then hardens to form an impermeable hydrophobic layer (repels water) up to 5 mm into the wood. As a preservative it is effective for exterior work above and below ground, but the thin layer makes it less useful in practice
