Summary: Wind speed sensor is a common sensor that can continuously measure wind speed and air volume (air volume = wind speed x cross-sectional area). Wind speed sensors are generally divided into mechanical (mainly propeller type, wind cup type) wind speed sensor, hot air wind speed sensor, pitot tube wind speed sensor and ultrasonic wind […]

Summary: With the continuous progress of society and the rapid development of science and technology, scientific soil testing and scientific fertilization have become a way advocated by large-scale agricultural planting. For soil detection, it is not only able to detect soil nutrients. There are many elemental indexes, and different soil sensors can be used to

Background： There are three traditional methods for monitoring soil moisture temperature, conductivity and PH in farmland. They are: indirect determination, direct determination, remote sensing and field GPS positioning method. However, these three monitoring methods or cumbersome process, inconvenient operation. Or it’s too simple to be accurate. Or it takes time and money. In a word,

Background： Agricultural water consumption accounts for more than 60% of the total water consumption in China. Irrigation water accounted for the largest proportion of agricultural water, up to about 90%. China’s severe water shortage, the United Nations as one of the world’s 13 water poor countries. With the continuous development of China’s economy, the rational

Summary: Due to the strong local and diurnal variation of rainfall, it has been difficult to quantitatively measure rainfall on a daily basis. However, with the progress of science and technology, the rapid development of electronic sensors, we used to detect rainfall rainfall gauge from artificial rainfall sensor, siphon rainfall sensor developed to today’s tipping

Summary: Illuminance sensor is a common detection device and has certain applications in many industries. In many places we see light-operated switch this kind of equipment, such as street lamps, each automatic weather station and agricultural greenhouses, but there was a ball when we see the box, although know this is a light sensor, but

Summary: Evaporation sensor is used to sense the change of water evaporation sensor, can observe the change rule of water evaporation in different time, suitable for meteorological observation, plant cultivation, seed cultivation, agriculture and forestry, geological survey, scientific research and other fields. Can be used with data acquisition sending device and other supporting, evaporation process

Background: Whether there is a harvest or no harvest depends on the water, and the more and the less depends on the fertilizer. This proverb is used in agriculture to emphasize the importance of water and fertilizer for plant growth. In summer, the temperature rises in most parts of the country, and droughts and floods

Background： According to relevant statistics, the annual agricultural water consumption accounts for 65% of the total water consumption. The utilization rate of its irrigation water is only 40%. Compared with the high utilization rate of 70%-80% in advanced water-saving countries, the gap is obvious. Due to the unreasonable use of water and fertilizer, a series

Summary: The tipping bucket rain sensor is a kind of hydrological and meteorological instrument, which is used to measure the natural rainfall and convert the rainfall into digital information output in the form of switching quantity, so as to meet the needs of information transmission, processing, recording and display. The 0.2, 0.5 mm tip bucket
