What should be paid attention to when installing a weather station
Do you know where to mount weather station?
The weather station should be installed as far as possible on the open ground without any obstructions, or 10 feet above the top of the surrounding buildings. Choosing the correct address is the most important step in the weather station installation project because it determines the accuracy of the measurement data.
When choosing the location of the weather station, you need to consider its impact on wind speed and direction sensors, temperature and humidity sensors, solar radiation sensors, rain gauges, rain and snow sensors, etc. If there are obstructions around and close to the weather station, it will affect the measurement of wind speed and direction. If the weather station is installed under a tree or there is an obstruction on top of it, your rainfall measurement will be biased. If the bottom is not installed flat, the overall weather station tilt will also affect the measurement accuracy.
Best place to put weather station sensors
1. Temperature and humidity sensor installation
The temperature and humidity sensor should be installed at 10 feet from the ground as the best measurement position. There are no obstructions or heat-dissipating objects around it, and there is no shadow for 24 hours a day. The surface of the support plate where the temperature and humidity sensor is installed should be rough, not reflective, and not dark. Clean the sensor housing once a year in a normal environment, and clean the housing once every three months in high sandy areas to reduce measurement errors.
2. Wind speed and direction installation
If there is no obstruction within a radius of 330 feet around the weather station, it can be installed on a pole 10 feet above the ground. If there are buildings or shelters around, they should be installed at a height of 10 feet from the top of the tallest surrounding building. The purpose is to reduce the influence of surrounding buildings on wind speed and direction.
3. Rain gauge installation
The rain gauge should be installed at a height of 10 feet from the ground with no obstructions around and on the top. When installing, make sure that the rain gauge stands perpendicular to the beam and the beam is parallel to the ground. As we all know, if the rain gauge is tilted, the measurement will occur error. The rain gauge should be cleaned as regularly as possible. In windy weather, leaves and sand are prone to fall into the funnel and block the leak.
4. Rain and snow sensor installation
The rain and snow sensor can be installed on a beam 10 feet above the ground to ensure that there is no obstruction on the top. Install the sensor at an angle of 15° to help water or snow slip off. If there is icing on the top, the sensor can melt the ice into the water through the automatic heating function to make it fall, so as not to affect its winter use.
5. Solar radiation sensor installation
The installation environment of the solar radiation sensor must ensure that there is no shadow obstruction 24 hours a day, and there is no sun refraction around it. Try to install it horizontally as much as 10 feet above the top of surrounding buildings. For environments with high dust concentrations, the surface of the sensor can be wiped regularly. Prevent the falling dust from being too thick and affecting accuracy.
6. Negative oxygen ion detector installation
It is best to install the negative oxygen ion detector vertically in a waterproof box 7 feet away from the ground. After installation, make sure that the hole at the bottom of the waterproof box is unobstructed. Perform a calibration before measuring.
7. Soil sensor installation
There are two ways to install the soil sensor: one is to insert the probe of the soil sensor vertically into the soil (the depth should be ≥7cm), avoiding rocks and hard objects. The other is to dig a 20cm deep soil pit, insert the soil sensor probe horizontally into the pit and fill it with compaction.
