{"product_id":"dragino-wss-23","title":"Dragino WSS-23, CO2 and particulate matter sensor PM2.5\/PM10, RS485","description":"\u003cp dir=\"ltr\"\u003eThe Dragino WSS-23 records CO2 concentration as well as PM2.5 and PM10 fine dust fractions simultaneously in one device. CO2 is measured using the NDIR method with internal temperature compensation, and fine dust is measured via laser scattering. A weather-resistant protective housing shields the measuring technology from UV radiation and sunlight, and connection is established via RS485 to the Dragino WSC2-L weather station.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eKey features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\n\u003cli\u003eThree measured variables in one device: CO2, PM2.5 and PM10\u003c\/li\u003e\n\n\u003cli\u003eCO2 measurement based on the NDIR principle (non-dispersive infrared absorption) with internal temperature compensation\u003c\/li\u003e\n\n\u003cli\u003eFine dust measurement via laser scattering\u003c\/li\u003e\n\n\u003cli\u003eWeather-resistant protective housing against UV radiation and sunlight\u003c\/li\u003e\n\n\u003cli\u003eRS485 interface with Modbus command set, operable directly on the WSC2-L main unit (standard baud rate 4800)\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\u003eCO2\u003c\/em\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\n\u003cli\u003eMeasurement principle: NDIR with temperature compensation\u003c\/li\u003e\n\n\u003cli\u003eMeasurement range: 0 to 5000 ppm\u003c\/li\u003e\n\n\u003cli\u003eResolution: 1 ppm\u003c\/li\u003e\n\n\u003cli\u003eAccuracy: ±3 % of full-scale value at 25 °C (corresponds to ±150 ppm)\u003c\/li\u003e\n\n\u003cli\u003eOperating temperature: 0 °C to +50 °C\u003c\/li\u003e\n\n\u003cli\u003eOperating humidity: 0 to 95 % RH\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cem\u003ePM2.5 \/ PM10\u003c\/em\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\n\u003cli\u003eMeasurement principle: Laser scattering\u003c\/li\u003e\n\n\u003cli\u003eMeasurement range: 0 to 1000 µg\/m³\u003c\/li\u003e\n\n\u003cli\u003eResolution: 1 µg\/m³\u003c\/li\u003e\n\n\u003cli\u003eAccuracy: ±3 % of full-scale value at 25 °C (corresponds to ±30 µg\/m³)\u003c\/li\u003e\n\n\u003cli\u003eOperating temperature: -30 °C to +50 °C\u003c\/li\u003e\n\n\u003cli\u003eOperating humidity: 15 to 80 % RH, non-condensing\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cem\u003eGeneral\u003c\/em\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\n\u003cli\u003eSupply voltage: 7 to 24 V DC\u003c\/li\u003e\n\n\u003cli\u003eCurrent consumption: 50 mA at 12 V\u003c\/li\u003e\n\n\u003cli\u003eWarm-up time: 3 min\u003c\/li\u003e\n\n\u003cli\u003eInterface: RS485\u003c\/li\u003e\n\n\u003cli\u003eStandard baud rate (with WSC2-L): 4800\u003c\/li\u003e\n\n\u003cli\u003eDimensions: 24 × 24 × 15 cm\u003c\/li\u003e\n\n\u003cli\u003eWeight: 1248 g\u003c\/li\u003e\n\n\u003cli\u003eScope of delivery: 1 × WSS-23\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e The CO2 measurement is specified for temperatures from 0 °C, and the fine dust measurement for non-condensing conditions up to 80 % RH.
