Rain and snow sensors are mainly used to detect whether there is rain or snow in nature weather measuring instruments. This sensor adopts AC impedance measurement method. The electrode has a long service life and will not cause oxidation problems. The rain and snow sensor can be widely used in the qualitative measurement of the presence or absence of rain and snow in the environment, greenhouses, breeding, buildings, buildings, etc. It is safe and reliable, beautiful in appearance and easy to install.
The working principle of the rain and snow sensor:
Rain monitoring: grid electrodes are used above the rain and snow sensor. Utilizing the conductivity of water, when rain water falls on the sensing area, it will cause the electrode to short-circuit. In this way, the device can detect rain.
Monitoring snowfall: The reason why the rain and snow sensor can measure snowfall is. The sensor has an automatic heating function. It is snowing, the temperature is lower than 0℃ for a long time, and the high humidity environment. Can prevent freezing and condensation. And the heating temperature can be set.
Application of weather measuring instruments rain and snow sensor:
The practical application of rain and snow sensor (rain)
Rain and snow sensors can be used in smart greenhouses. In the rainy season, the smart rain and snow sensor can predict the signal of rain. Use linkage control equipment to avoid rain and provide timely warning. So that the planting can respond in time and reduce the loss caused by heavy rain.
Practical application of rain and snow sensor (snow)
Rain and snow transmitters can be used on highways or railway tracks. The rain and snow sensor has an automatic heating function. It is snowing, the temperature is lower than 0℃ for a long time, and the high humidity environment. The rain and snow sensor grid will be automatically heated to prevent data deviation due to icing and dew. After the rain and snow sensor detects the snowfall, it can pass through the corresponding highway weather station or railway weather station. Upload the data to the cloud platform and cooperate with other sensors to make accurate judgments on the amount of snowfall. Remind drivers who are still on the highway or already on the highway to prepare early.
