Summary:
Rain and snow sensors are mainly used to detect whether there is rain or snow in nature. The sensor uses AC impedance measurement method, electrode life is long, no oxidation problem.
The rain and snow sensor can be widely used in environment, greenhouse, aquaculture, construction, buildings, such as the qualitative measurement of rain and snow, safe and reliable, beautiful appearance, easy to install.
Working principle of rain and snow sensor:
Rain monitoring: the sensor 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 sensor can measure snow is that the sensor has an automatic heating function, which can prevent freezing and dew in snowy, temperature below 0℃ for a long time and high humidity environment. And the heating temperature can be set.
Application of rain and snow sensor:
Practical application of rain and snow sensors (rain)
Rain and snow sensors can be used in smart greenhouses. In plum rain season, intelligent sensor can predict the signal of rain, through the linkage control equipment for rain shelter, timely warning, so that the timely response of planting, reduce the loss caused by heavy rain.
Practical application of rain and snow sensors (snow)
Rain and snow transmitters can be used on highway or railway tracks. The sensor with automatic heating function. In snowy, long-term temperature below 0℃ and high humidity environment, the sensor grid will be automatically heated. It can prevent data deviation caused by ice and dew.
