Rain and Snow Sensor

Rain and Snow Sensor product introduction:

Rain and Snow Sensor is a device specifically designed to measure whether it rains or snows outdoors or in nature, usually used in fields such as meteorological observation.

Measure whether there is rain or snow, the response time is ≤0.5S.

AC measurement technology prevents oxidation reactions on the sensing plate and ensures long-term sensitivity.

Designed with IP68 protection level, it can work outdoors for a long time.

A variety of transmission methods are available, providing 485 mode upload or switch output to facilitate centralized monitoring.

Optional automatic heating function can be used for snow detection to prevent freezing in situations where the temperature is below 0 degrees for a long time and in high-humidity environments.

When heating, the temperature is strictly controlled within 40°C (default) to prevent overoxidation caused by dry burning and extend the service life.

The sensor sensitivity is adjustable, making it more flexible to use.

Alarm and return delays can be set to avoid frequent alarms on site.
