{"product_id":"dragino-wss-25","title":"Dragino WSS-25, temperature, humidity, light, and barometric pressure sensor, RS485","description":"\u003cp dir=\"ltr\"\u003eThe Dragino WSS-25 is a 4-in-1 sensor that simultaneously measures air temperature, relative humidity, illuminance, and air pressure. All measuring elements are housed in a UV-resistant radiation shield, which protects temperature and humidity measurements from distortion caused by direct sunlight. Output is via RS485 using the standard Modbus RTU protocol, allowing the sensor to be operated with both the Dragino WSC2-L weather station and any other Modbus master.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eMain Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\n\u003cli\u003eFour measured variables in one device: temperature, relative humidity, illuminance, and air pressure\u003c\/li\u003e\n\n\u003cli\u003eUV-resistant radiation shield for permanent outdoor use\u003c\/li\u003e\n\n\u003cli\u003eRS485 with standard Modbus RTU protocol, factory device address 13 (0x0D)\u003c\/li\u003e\n\n\u003cli\u003eCan be operated directly on the WSC2-L main unit (standard baud rate 4800)\u003c\/li\u003e\n\n\u003cli\u003ePower supply 10 to 30 V DC, maximum power consumption 0.8 W\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cem\u003eGeneral\u003c\/em\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\n\u003cli\u003eSupply voltage: 10 to 30 V DC\u003c\/li\u003e\n\n\u003cli\u003ePower consumption: max. 0.8 W\u003c\/li\u003e\n\n\u003cli\u003eInterface: RS485, Modbus RTU\u003c\/li\u003e\n\n\u003cli\u003eStandard baud rate (with WSC2-L): 4800\u003c\/li\u003e\n\n\u003cli\u003eFactory device address: 13 (0x0D)\u003c\/li\u003e\n\n\u003cli\u003eScope of delivery: 1 × WSS-25\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cem\u003eTemperature\u003c\/em\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\n\u003cli\u003eMeasuring range: -40 °C to +120 °C\u003c\/li\u003e\n\n\u003cli\u003eResolution: 0.1 °C\u003c\/li\u003e\n\n\u003cli\u003eAccuracy: ±0.5 °C at 25 °C\u003c\/li\u003e\n\n\u003cli\u003eLong-term stability: ≤ 0.1 °C per year\u003c\/li\u003e\n\n\u003cli\u003eResponse time: ≤ 25 s (τ63, at 1 m\/s airflow in the housing)\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cem\u003eRelative Humidity\u003c\/em\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\n\u003cli\u003eMeasuring range: 0 to 99 % RH\u003c\/li\u003e\n\n\u003cli\u003eResolution: 0.1 % RH\u003c\/li\u003e\n\n\u003cli\u003eAccuracy: ±3 % RH at 60 % RH and 25 °C\u003c\/li\u003e\n\n\u003cli\u003eLong-term stability: ≤ 1 % RH per year\u003c\/li\u003e\n\n\u003cli\u003eResponse time: ≤ 8 s (τ63, at 1 m\/s airflow in the housing)\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cem\u003eAir Pressure\u003c\/em\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\n\u003cli\u003eMeasuring range: 0 to 120 kPa (0 to 1200 hPa)\u003c\/li\u003e\n\n\u003cli\u003eResolution: 0.1 kPa (1 hPa)\u003c\/li\u003e\n\n\u003cli\u003eAccuracy: ±0.15 kPa (±1.5 hPa) at 25 °C and 101 kPa\u003c\/li\u003e\n\n\u003cli\u003eLong-term stability: -0.1 kPa per year\u003c\/li\u003e\n\n\u003cli\u003eResponse time: ≤ 2 s\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cem\u003eIlluminance\u003c\/em\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\n\u003cli\u003eMeasuring range: 0 to 200,000 lx\u003c\/li\u003e\n\n\u003cli\u003eResolution: 1 lx\u003c\/li\u003e\n\n\u003cli\u003eAccuracy: ±7 % at 25 °C\u003c\/li\u003e\n\n\u003cli\u003eLong-term stability: ≤ 5 % per year\u003c\/li\u003e\n\n\u003cli\u003eResponse time: ≤ 2 s\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eApplications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\n\u003cli\u003eAgricultural weather stations based on the Dragino WSC2-L as a base module for climate and light data\u003c\/li\u003e\n\n\u003cli\u003eFrost and disease warning in fruit growing, viticulture, and vegetable farming based on temperature and humidity\u003c\/li\u003e\n\n\u003cli\u003eLocal weather observation and climate monitoring in municipalities, on company premises, or at schools\u003c\/li\u003e\n\n\u003cli\u003eIntegration into existing Modbus RTU systems, e.g., PLC or building management systems, for recording outdoor climate and daylight\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli dir=\"ltr\"\u003e\u003ca href=\"https:\/\/wiki.dragino.com\/docs\/Non-Wireless-Sensors\/agriculture-weather-stations\/wss-25-temperature-humidity-illuminance-pressure-new-version\" target=\"_blank\" rel=\"noopener\"\u003eUser Manual\u003c\/a\u003e\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"Dragino","offers":[{"title":"Default Title","offer_id":55345638474055,"sku":"WSS-25","price":83.2,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0761\/6561\/1847\/files\/WSS-25.jpg?v=1791478207","url":"https:\/\/exp-tech.de\/en\/products\/dragino-wss-25","provider":"EXP Tech","version":"1.0","type":"link"}
