The Best Rain And Snow Sensor From JXCT

What is the rain and snow sensor?

A rain and snow sensor is a qualitative weather instrument used to measure whether it is raining or snowing outdoors or in nature. Equipped with imported intelligent microprocessor and advanced detection circuit. Grid electrodes are used on the surface to take advantage of the conductive properties of water. When it falls in the induction zone in rain or snow, it can cause the electrode to short-circuit. At this point, the device can detect rain or snow and send alarm information to the administrator as soon as possible. It can be widely used in environment, greenhouses, agriculture, buildings, buildings and other qualitative measurement of rain and snow. Safe and reliable, beautiful appearance, easy installation.

Rain And Snow Sensor

JXCT rain and snow sensors can work in an environment of -40℃~80℃. In order to prevent the surface of rain and snow transmitters from freezing and condensing in a low-temperature environment, the rain and snow sensor is designed with an automatic heating function. Equipped with a temperature and humidity sensor. When the temperature and humidity sensor detects that the ambient temperature is lower than 15°C, the device will automatically turn on the heating function, and the heating function will be turned off when the device temperature reaches 40°C. At the same time, users can also reset which temperature to start heating according to the specific situation of the place of use. It should be noted that the temperature should be strictly controlled within 40 ℃ during heating to prevent dry burning from causing over-oxidation and affecting the service life.

Precautions for the use of rain and snow sensor

1, In autumn and winter, due to the cold weather, water vapor will condense into fog or frost and fall on the sensor’s sensing area. After they melt into water, they will trigger the sensor of the transmitter, falsely reporting it as snowy weather. In order to avoid such situations, the rain and snow transmitter is used flexibly, and its sensitivity value can be adjusted according to the specific situation. The sensitivity value is inversely proportional to the actual sensitivity. The larger the sensitivity value, the less sensitive the device detection, the smaller the sensitivity value, the more sensitive the device detection. To avoid false alarms, the general sensitivity value is set to 800 by default at the factory.

2, Once the rain sensor detects rain or snow, it will send an alarm message to the manager as soon as possible. Therefore, during a period of rain or snowfall, it is annoying to continuously send warning messages to managers. To solve this trouble, the user can set the alarm and reset the delay through the device software. If we set the device’s alarm and reset the delay value to 10S, then it will output alarm information when the duration of rain and snow is detected exceeds 10S, if the duration of rain and snow is detected is less than 10S, the device It is considered that no rain or snow is detected; at the same time, the same is true when rain and snow return to a normal state.
