ECOWITT WN90LP RS485 Electronic Weather Station with Modbus Protocol

• This RS485 product requires a wired connection to the host. Please note that we do not currently offer a wireless console that supports the RS485 interface sensor. Users need to use RS485 wired connections to enable communication and data transfer between the sensor and the host.
• The WN90LP is a wired RS485 version of the WS90 weather sensor. The solar panel has been removed, and the power connection is replaced with an RS485 interface, making it easier to integrate into professional data acquisition systems.
• Wind measurements ultrasonic anemometer (start wind speed 0.3m/s); The original temperature and humidity module is upgraded to a temperature, humidity, and barometric pressure sensor, delivering more comprehensive data.
• To improve temperature accuracy, the sensor adopts a temperature compensation design (US Patent No. 12,181,491B2), which effectively reduces thermal interference caused by direct sunlight or heater power supply.
• The rain sensor features a sloped surface design that optimizes water collection flow and impact characteristics, resulting in enhanced rainfall measurement accuracy.
• Like the WS90, the WN90LP maintains a fully electronic, no-moving-parts design, ensuring higher durability and reliability for long-term outdoor professional applications.
