Rain and snow sensors are mainly used to detect whether there is rain or snow in nature. This sensor adopts AC impedance measurement method. The electrode has a long service life. There will be no oxidation problems. The rain and snow sensor can be widely used in the environment, greenhouses, breeding, construction, buildings, etc. The qualitative measurement of the presence or absence of rain and snow is safe and reliable. Beautiful appearance and easy installation.
The working principle of the rain and snow sensor
Rain monitoring: grid electrodes are used above the rain and snow sensor. Utilize the conductivity of water. When rain falls on the sensing zone. 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. In snow, the temperature is below 0℃ for a long time, and the high humidity environment. Can prevent freezing and condensation. And the heating temperature can be set.
Application of rain and snow sensor:
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. Avoid rain through linkage control equipment. Early warning. In order to plant this timely response. Reduce losses caused by heavy rains.
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. In snow, the temperature is below 0℃ for a long time, and the high humidity environment. The rain and snow sensor grid will automatically heat up. It can prevent data deviation caused by icing and condensation. 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. After cooperating with other sensors to make an accurate judgment on the amount of snowfall. Remind drivers who are still on the highway or already on the highway to prepare early.
