Feature

●Response Time and Alarm Reset Delay: The response time of rain and snow measurement is less than or equal to 0.5s. Alarm and reset delay can be set to avoid frequent field alarms.
●Automatic Heating: The automatic heating function can be used for snow detection to prevent freezing and condensation when the temperature is lower than 0 ℃ for a long time and the humidity is high.
●Safe and Sensitive: The rain and snow sensor is safe, reliable, beautiful and easy to install. The sensitivity of the sensor is adjustable for more flexible use.
●AC Measurement Technology: The unique AC measurement technology prevents the oxidation reaction of the sensing plate and ensures long term sensitivity.
●Heating Temperature Range: The temperature during heating shall be strictly controlled within 40 ° C (default value) to prevent excessive oxidation caused by dry burning and prolong the service life.

Description of Alarm Reset Delay Setting
If this value is set to 10S, the device will not consider that it has detected rain and snow and output alarm status until the duration of rain and snow detection exceeds 10S; if the duration of rain and snow detection is less than 10S, the device will consider
