The rain and snow IoT Meter / IoT Sensor is used for reliable detection of precipitation and is used to monitor weather conditions in environmental stations, for irrigation control systems or in industrial plants. The rain and snow IoT Meter / IoT Sensor enables a quick and reliable response to rain or snow. The IoT Meter / IoT Sensor qualitatively detects the presence of precipitation via conductivity and condensation properties and provides the information digitally via RS-485 Modbus RTU and via a potential-free relay output, which can be used to directly switch external devices or controls.

The integrated relay output is designed as a normally open contact and provides galvanic isolation between the IoT Meter / IoT Sensor voltage and the switched circuit. This allows both low-voltage and mains voltage applications to be implemented. The maximum switching capacity of the relay is 250V AC at 1 A or 30V DC at 1 A, making the IoT Meter / IoT Sensor suitable for direct control of controllers, actuators or relays.

The supply voltage of the rain and snow IoT Meter / IoT Sensor is 24 to 30V DC. The compact, corrosion-resistant housing is IP65-rated and designed for surface mounting. An automatic heating function activates at lower temperatures below 0°C / 32°F ambient temperature and heats the IoT Meter / IoT Sensor surface to approximately 40°C / 104°F to prevent ice formation. This ensures that the rain and snow IoT Meter / IoT Sensor works reliably even in frosty conditions. It is mainly used by weather station operators, environmental researchers, in irrigation systems and in industrial applications where precipitation needs to be reliably detected and automated responses implemented.
