The Dragino WSS-24 is a RS485 Rain & Snow Detect sensor designed to monitor precipitation events in weather station and smart agriculture deployments.
It detects whether rain or snow is present and reports a clear/detected status to the connected system.
The sensor features a surface auto-heating function that dries the detection grid, improving reliability in humid, icy, or snowy conditions.
It uses an industrial RS485 interface for easy integration with PLCs, data loggers, and LoRaWAN RS485 converters such as Dragino weather station controllers.
Built with a robust housing, the sensor offers excellent resistance to water, dust and corrosion — ideal for long-term field deployments. Compatible with Dragino LoRaWAN® Weather Station Controller WSC2-L, the WSS-24 integrates seamlessly into your IoT network and supports EU868 frequency band (to operate the sensor over LoRaWAN, it must be connected to the WSC2-L controller).
