Difference between wind speed sensor and air volume sensor The difference between the wind speed sensor and the air volume sensor starts with the wind speed and the air volume. Wind speed refers to the velocity of air relative to a fixed location on the earth. The common unit is m/s, 1m/s=3.6 km/h. Wind speed […]

At present, tipping bucket rain gauges, siphon rain gauges, ultrasonic rain gauges, etc. are more common in meteorological monitoring. They belong to different types of rain gauges, and their monitoring principles are different: Siphon rain gauge The siphon rain gauge can continuously record the amount of liquid precipitation and the number of precipitation hours, and

Negative ions are essential for both environmental protection and health. Firstly, from an environmental perspective, the concentration of negative oxygen ions in the air is considered one of the indicators of air quality. The World Health Organization has established standards for negative ion concentration in the air. When the concentration of negative oxygen ions in

The multi-layer soil moisture sensor is a technology that measures soil moisture regularly and at fixed points through technical means such as instruments and equipment, and grasps the dynamic law of soil moisture changes. Soil moisture monitoring can not only designate a targeted irrigation system based on local planting patterns but also realize early warning

It is widely known that ultraviolet (UV) radiation is prevalent in the natural environment, primarily originating from solar. While most UV radiation is absorbed by the Earth’s atmosphere and the ozone layer, a portion of it reaches the Earth’s surface. Moderate exposure to UV radiation is beneficial for both human health and ecosystems, but excessive

Only when the soil pH value is about 6.5, the absorption and utilization of nutrient elements are the highest, which is also the most beneficial to the growth and development of crops. Therefore, the role of soil pH sensor is indispensable, so how should we choose this kind of equipment? Pay attention to the measurement

Gas sensors application in a wide range. Mainly used to detect the concentration of gas, such as carbon dioxide, oxygen, nitrogen, argon, etc. In the industrial field, gas sensors are often used in gas leak detection, industrial ventilation systems, and gas sensor fault detection. In the medical field, gas sensors also have high application value,

What is temperature humidity sensor? Temperature and humidity sensor (or rh temp sensor) is devices that can convert temperature and humidity into electrical signals that can easily measure temperature and humidity. Temperature humidity transmitters on the market generally measure the amount of temperature and relative humidity in the air, and convert it into electrical signals
