What is a weather sensor?

Weather sensors are special equipment used to understand and measure climate change. These sensors are usually mounted in combination on fixed poles or near shore to record average lake conditions. There are many important factors affecting meteorological changes, such as temperature, humidity, wind speed and direction, rainfall, radiation and so on. These weather sensors use different principles to reflect weather fluctuations by converting internal voltage changes into electrical signals. These meteorological sensors can detect local weather conditions, automatically collect meteorological information, and timely provide accurate meteorological information for meteorologists.

Wind speed and direction sensor

Wind speed and direction are important parameters in meteorological monitoring. Therefore, wind speed and direction sensors are the most important types of meteorological sensors. From a scientific point of view, the movement of air can be divided into vertical and horizontal parts. The vertical part is called the vertical motion of air (for example, convection motion). Wind is the horizontal movement of air. It is a vector. Wind moves with both speed and direction. Therefore, the observation of wind includes wind direction and wind speed. In order to obtain certain representative wind speed and direction data during observation, the average wind speed and maximum wind direction in a certain period are generally taken.

In meteorological research, it is often necessary to observe various natural phenomena, such as changes in wind speed and weather, and of course, changes in wind direction. For the measurement of wind direction, the wind vane or wind direction sensor is basically used to solve this problem. It includes environmental monitoring and control of ports and wharfs, monitoring and control of weather stations and environmental protection, monitoring and control of construction machinery operation process, monitoring and control of high altitude operation, monitoring and control of other industrial processes related to wind speed and direction safety, etc.

T/H sensor

Humidity and temperature are inseparable factors affecting meteorological changes. The temperature commonly observed in meteorology is air temperature. Humidity is usually measured as relative humidity. Different weather systems often cause changes in the temperature of an area. Usually cold air brings cooling, warm air brings heating, wind and precipitation bring cooling. Changes in measured temperature can reflect changes in local climate.

Solar radiation sensor

Solar radiation is the most important external energy source, and even small changes in it can lead to huge changes in the global environment and weather. Solar radiation is one of the important causes of the earth’s weather and climate change. Climate change and weather forecast need the information of solar radiation. Meteorological solar radiation has a wide range of wavelengths. Total solar radiation is usually measured, which is the sum of direct and scattered radiation from the sun. The direct solar radiation that reaches the earth’s surface is called direct solar radiation after attenuation by atmospheric scattering and absorption. When passing through the atmosphere, it is scattered by gases, dust and aerosols in the atmosphere and reaches the surface from all angles of the sky, which is called solar scattered radiation.

The rain gauge

Rainfall is one of the most common meteorological conditions. Rainfall monitoring is an important basis for calculating regional water resources and meteorological research. The change of precipitation has a direct impact on surface river runoff, which can provide data analysis for the prediction and prevention of flood disasters. In addition, precipitation affects the growth and development of crops, which can promote agricultural production. As a result, rain gauges are often installed at weather stations to monitor rainfall.
The rain gauge commonly used in weather tests is made of ABS and stainless steel. The difference between the two is that ABS rain gauge is light weight and easy to install. Cheaper than stainless steel rain gauges. But stainless steel rain gauges are more accurate. Stainless steel corrosion resistance, can be used in harsh environment for a long time. The most widely used weather sensor is the stainless steel rain gauge.

Evaporation sensor

There are meteorological sensors that can measure rainfall and also instruments that can measure evaporation. Evaporation is an integral part of the surface heat balance and water balance, and is also directly affected by climate change in the water cycle. Evaporation is a factor of heat energy exchange. Therefore, evapotranspiration has important application value in estimating terrestrial evaporation, crop water demand and crop water balance. Measuring the change of evaporation is of great significance for in-depth understanding of climate change and discussion of water cycle.


In meteorological monitoring, evaporation sensors are often used to observe water surface evaporation. The shell is designed with double-layer stainless steel, which can prevent evaporation errors caused by direct sunlight. The measurement accuracy is relatively accurate, and the stainless steel material is corrosion-resistant, which can prolong the service life of the sensor. It can be used with rain gauges for automatic measurement and remote transmission of evaporation and rainfall processes.
