Reliable Rain Snow Sensor,Switch Type 485 Rain and Snow Transmitter Detection Densor

Reliable Rain Snow Sensor,Switch Type 485 Rain and Snow Transmitter Detection Densor Description

Wiring Instructions: Voltage power input can be 10~30V. When wiring the 485 signal cable, pay attention to the A/B. The two wires cannot be connected in reverse. The addresses between multiple devices on the bus cannot conflict. The switch type device comes standard with 1 relay output, and the two outgoing wires (green and white) are normally open contacts.
Alarm Reset Delay Setting D If this value is set to 10S, if the rain and snow are detected for more than 10S, the device will detect that the device has detected rain and snow and output an alarm state. If the rain and snow are detected for less than 10 seconds, the device does not consider it to be detected. To the rain and snow; when the rain and snow return to normal state, the same reason. Default: 1 second Range: 0~60000 seconds
Sensitivity Setting The sensitivity value is inversely proportional to the actual sensitivity. The larger the setting value, the less sensitive the device detection is. The smaller the sensitivity value is, the more sensitive the device detection is. However, it should be noted that the sensitivity value is too small and it is easy to cause false alarms. It is recommended to use the factory default values. Default: 800 Range: 500-3500
IP68 protection grade design, can work outdoors for a long time, easy to use, suitable for a variety of harsh site environment. The temperature of heating should be controlled within 40 (default) to prevent peroxidation caused by dry burning and prolong the service life. Sensor sensitivity adjustable, more flexible use. Alarm and reset delay can be set to avoid frequent alarm on site.
Optional automatic heating function, can be used for snow detection, in the case of long-term below 0 and high humidity environment, to prevent icing condensation. Can be widely used in the environment, greenhouse, aquaculture, construction, buildings, such as the existence of rain and snow qualitative measurement, safe and reliable, beautiful appearance, easy installation.
