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.
