Couldn't load pickup availability
Currently out of stock. Restocking is expected in late December 2026 or early January 2027. We will open the product for sale approximately two weeks before the stock arrives.
Features
The WN69LP is a wired RS485 version of the WS69 7-in-1 weather sensor. By removing the solar panel and wireless RF module, the device now features a direct RS485 interface, specifically designed for seamless integration into professional data acquisition systems and industrial PLC environments.
- Integrated Measurement: Captures outdoor temperature, humidity, wind direction, rainfall, wind speed, UV, and light intensity in a single unit.
- Enhanced Sensing: Upgraded with a high-precision thermo-hygro-barometer sensor for comprehensive atmospheric data.
- Professional Reliability: Features a wired connection for stable data transmission, eliminating RF interference and range limitations.
- Industry Standard: Supports Modbus protocol for easy communication with third-party controllers and monitoring software.
Regarding power supply, protocol, and lightning protection for installation:
Power supply: The device's power supply is RS485 power's line between 6 ~ 24.0 V. Do not attempt to install batteries.
Protocol: The WN69LP operates as a Modbus Slave device. For specific register maps, baud rate settings, function codes, and detailed command structures, please refer to the separate technical document:
"Ecowitt RS485 Modbus RTU Protocol Specification for WN69LP Series".
Installation & Lightning Protection: Please refer to: Lightning Protection Guidelines. Sensor damage, due to lack of grounding-protection against lightning ESD discharge, is not covered by warranty.
