Rain and Snow Sensor

Rain and Snow Sensor Product Introduction:

Measure the presence or absence of rain and snow, with a response time of ≤0.5S.

AC measurement technology prevents oxidation of the sensing disc and ensures long-term sensitivity.

IP68 protection grade design, can work outdoors for a long time.

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

The optional automatic heating function can be used for snow detection to prevent ice formation in places 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℃ (default) to prevent dry burning and overoxidation, thus extending the service life.

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

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