Summary:
Rain and snow, both natural precipitation phenomena, are caused by disturbances in the atmospheric circulation and are an integral part of the earth’s water cycle. They are also the only way to replenish water for terrestrial organisms that live far from rivers and lakes. Precipitation is the origin of surface runoff and the main recharge source of groundwater. The inhomogeneity of spatial distribution and the instability of time variation of precipitation are the direct causes of flood, waterlogging and drought. So it needs to be detected, and rain and snow sensor do the job.
There are two types of rain and snow sensors: rain gauges, which measure rainfall, and rain and snow sensors, which monitor whether rain or snow is falling.
Rain and snow sensor is one of the components of the weather monitoring system, the equipment is a special for measuring outdoor or natural whether rain or snow equipment. Rain and snow sensors are widely used in meteorology, agriculture, industry, ocean, environment, airport, port and traffic and other fields for qualitative measurement of rain and snow.
Working principle:
Rain monitoring: the rain and snow transmitter above the grid electrode, the use of water conductivity, when rain falls on the induction zone, will cause electrode short circuit, so that the equipment can monitor the rain.
Snow monitoring: the reason why the rain and snow transmitter can measure snow is that the sensor has an automatic heating function, which can prevent icing and dew in snowy, temperature below 0℃ and high humidity environment for a long time. And the heating temperature can be set.
Practical application (rain):
Rain and snow sensors can be used in greenhouse greenhouses. In the season of frequent storms, rain and snow transmitters monitor the rain information, through the corresponding system linkage greenhouse shelter equipment, at the same time to the greenhouse management personnel to send signals, can effectively reduce the loss of greenhouse crops.
In addition, in the case of weather that the farm managers do not pay attention to, when the system detects abnormal data, it will send a reminder to the growers within a set period of time. Even if they cannot arrive at the greenhouse site in time, the greenhouse managers can also take remote measures to reduce losses. In the case of no one, the rain and snow sensor can still automatically manage the greenhouse through parameter setting linkage related system, so that the vegetables in the greenhouse have been in a suitable growth environment.
Practical application (snow) :
Rain and snow transmitters can be used on highway or railway tracks. In northern China, highways and railways are often hit by wind and snow in winter. We all know that when the weather is bad, the highway is closed. Imagine the awkwardness of being stuck on a highway during a heavy snow storm because you don’t know what the weather is like.
Product Introduction:
Rain and snow sensor is a kind of qualitative measurement equipment to measure outdoor snow. The rain and snow transmitter has automatic heating function. In the case of snow, temperature below 0℃ and high humidity environment for a long time, the rain and snow sensor grid will automatically heat, which can prevent data deviation caused by ice condensation. The rain and snow transmitter can monitor the snow through the corresponding road weather station or railway weather station, upload the data to the cloud platform, with other sensors to make an accurate judgment of the snowfall, remind the driver is still in the high speed or has been on the high speed to prepare.
