Multi-function sensor for automatic weather station
The multi-function automatic weather station is usually placed in bad conditions. Under the condition of human operation, it can collect and record the local weather. It can detect and record the temperature and humidity of the atmosphere, wind direction, wind speed and other meteorology all day long, so as to provide reference for people. Next, we will introduce the main functions of sensors in weather stations.
The multi-functional automatic weather station is composed of weather sensor, collector, power supply system, radiation proof ventilation cover, all-weather protection box and meteorological observation support, communication interface and peripheral equipment (computer, printer), etc. Temperature, humidity, wind speed and wind direction sensors are special outdoor weather sensors with high precision and high reliability. Sensor is very important for automatic weather station. In daily use, how to maintain the sensor of multi-function automatic weather station?
1. If there is dust on the air temperature and humidity sensor, it should be cleaned with a soft bristle brush instead of water. Replace the filter paper in time. It should be noted that the sensor should not be placed outside the shutter box during maintenance and cleaning.
2. Check whether the desiccant color in the still air hole of the atmospheric pressure sensor turns blue and whether there are impurities in the air inlet hole. It means to change the color of the desiccant.
3. The dust, sand, turf and insects on the rain sensor should be removed regularly, and the pollutants on the inner wall of the tipping bucket can be washed with water.
4. In order to ensure the measurement accuracy of wind sensor and avoid error, the wind sensor should be cleaned and maintained regularly. If the bearing is worn, etc., consider replacing it.
5. Check whether the surface temperature sensor and shallow ground temperature sensor change the surface soil, and ensure that the sensor is in the correct position and the cable is in good condition.
The power supply of the collector can ensure that the collector can work normally for at least seven days. The data memory can store at least three days' air pressure, air temperature, relative humidity, one minute average wind direction and wind speed, precipitation and hourly observation data of the items listed in the table below, which can form the specified data file in the computer. It has such a powerful function, absolutely inseparable from the sensor.
