DRAGINO 4-in-1 RS485 Weather Sensor for Temperature Humidity Light Pressure

What Is the DRAGINO 4-in-1 RS485 Weather Sensor for Temperature Humidity Light Pressure (WSS-25)?

The Dragino WSS-25 is a 4-in-1 RS485 weather and environmental sensor designed to monitor four important atmospheric parameters simultaneously:

• Temperature
• Relative humidity
• Illuminance
• Atmospheric pressure

The sensor is designed as part of the Dragino weather station solution. It communicates through an RS485 interface, allowing it to connect to compatible weather station controllers such as the Dragino WSC1-L and WSC2-L series. The connected weather station controller can collect the WSS-25 measurements and transmit them to an IoT server using wireless communication such as LoRaWAN.

By combining four environmental measurements into one sensor, the WSS-25 can help simplify weather monitoring installations and reduce the need to deploy multiple individual sensors.

How Does the WSS-25 Work?

• The sensor is installed at the monitoring location
  The WSS-25 is positioned where atmospheric conditions need to be measured.
• Temperature is measured
  The integrated temperature sensor measures ambient temperature from -30°C to 70°C.
• Humidity is measured
  The sensor monitors relative humidity from 0–100% RH.
• Atmospheric pressure is measured
  The integrated pressure sensor measures atmospheric pressure from 10–1100 hPa.
• Illuminance is measured
  The light sensor measures illumination across selectable ranges of 0–2 kLux, 0–20 kLux, or 0–200 kLux.
• Data is transmitted through RS485
  The four measurements are communicated through the RS485 interface to a compatible weather station controller or data acquisition system.
• The weather station controller processes the data
  A compatible Dragino weather station controller can collect the WSS-25 data and prepare it for remote transmission.
• Data can be uploaded to an IoT platform
  When integrated with a suitable LoRaWAN weather station controller, environmental measurements can be transmitted wirelessly to an IoT server for remote monitoring and analysis.

Why Choose the WSS-25?
