The automatic weather station can automatically observe, report and record. It is an unmanned ground weather observation station, mainly used to observe temperature, humidity, solar radiation, visibility and other on-site observations of all-weather climate.

　　The automatic weather station is composed of meteorological sensors, collectors, power supply systems, radiation protection hoods, all-weather protective boxes and meteorological observation brackets, communication interfaces and peripheral equipment (computers, printers) and other parts. Sensors such as temperature, humidity, wind speed and direction are special sensors for outdoor weather, which have the characteristics of high precision and high reliability. Sensors are very important to automatic weather stations. In daily use, how to maintain and maintain the sensors of automatic weather stations?

　　1. If there is dust on the air temperature and humidity sensor, it should be cleaned with a soft brush instead of water. Replace the filter paper in time. It should be noted that the sensor cannot be placed outside the louver box when maintaining and cleaning the sensor.

　　2. Check whether the color of the desiccant in the static air hole of the atmospheric pressure sensor turns blue, and whether there are impurities in the air inlet hole. If the desiccant color turns blue, it means that the desiccant needs to be replaced.

　　3. Regularly remove the dirt, sand, turf, insects, etc. on the rain sensor, and use water to wash the pollutants on the inner wall of the tipping bucket.

　　4. In order to ensure the measurement accuracy of the wind sensor and avoid errors, the wind sensor should be cleaned and maintained regularly. If the bearings are worn, etc., consider replacing them.

　　5. Check whether the surface temperature sensor and the shallow ground temperature sensor change the surface soil, make sure the sensor is in the correct position and the cable is intact.
