About - Rain and Snow Sensor
There are three output modes of this rain and snow sensor: RS485 output, relay output, and RS485+relay output. This rain and snow sensor has excellent craftsmanship, corrosion resistance, and can be used outdoors for a long time.
Features
The rain-snow sensor is one of the components of the weather monitoring system. It is a device specifically used to measure whether it rains or snows outdoors or in nature. The appearance of this rain sensor is made of high-strength ABS waterproof material, and the protection level is IP68. It senses rain and snow through the spiral metal coil on the top, and has an auto-heating function to avoid surface icing caused by severe cold weather in winter. When in use, an external sound and light alarm can be connected to increase the alarm function. Or use the free cloud platform provided by our company to achieve alarm.
- Measures rain and snow, with a response time of ≤0.5s.
- Unique AC measurement technology prevents oxidation of the sensing plate, ensuring long-term sensitivity.
- Optional automatic heating function enables snow detection, preventing icing and condensation in environments below 0 °C or with high humidity.
- Heating temperature is strictly controlled within 40 °C (default) to avoid overheating and oxidation, extending service life.
- Alarm and reset delay can be configured to prevent frequent on-site alarms.

Rain and snow sensor use
Rain and snow sensor can be used in greenhouses. In times of frequent heavy rains, after the rain sensor detects the rain information, it links the rain shelter of the greenhouse through the corresponding system and sends a signal to the greenhouse manager at the same time, which can effectively reduce the loss of greenhouse crops. Rain snow sensors can be used in outdoor weather station equipment to provide reference data for meteorological environment monitoring.
Rain and snow sensors can be used on highways or railway tracks. After the rain and snow sensor detects the snowfall, it can upload the data to the cloud platform through the corresponding highway weather station or railway weather station, and cooperate with other sensors to make accurate judgments of the snowfall, and remind you that it is still on the high speed or already on the high speed The driver’s master prepared early.
FAQs - Rain and Snow Sensor
When installing the rain and snow sensor, keep the sensing surface of the sensor and the horizontal plane at an angle of 15 degrees to prevent the accumulation of rain and snow from affecting the sensor measurement.
The rain and snow sensor is an instrument that uses the conductive characteristics of rainwater and uses advanced detection circuits to detect whether there is rain or snow.
- Rain monitoring: The top of the rain and snow sensor uses grid electrodes to use the conductivity of water. When rain falls on the sensing area, the electrodes will be short-circuited, so that the device can detect rain.
- Snow monitoring: The reason why the rain and snow sensor can measure the snowfall is that the sensor has an automatic heating function, which can prevent freezing and condensation in the snow, the temperature is lower than 0 ℃ for a long time, and the high humidity environment. And the heating temperature can be set.
After installing the rain sensor, take a small number of water droplets on the surface of the sensor. If the sensor alarms, it means that the sensor is normal.
When maintaining the rain and snow sensor, use a clean, dry soft cloth to clean the outside of the instrument to prevent the instrument from being scratched, maintain the integrity of the external protective film, and increase the service life of the instrument. Rough treatment of the instrument will destroy the internal circuit board and delicate structure.
