IP65 weatherproof protection: Designed for long-term outdoor deployment in agricultural, meteorological, traffic, solar, and wind power monitoring systems.
JW-XF400(YN20) Compact Weather Station Sensor is an integrated four-parameter micro weather station designed for continuous outdoor monitoring of air temperature, relative humidity, atmospheric pressure, and optical rainfall. With a compact structure, RS485 Modbus RTU output, IP65 protection, and DC9–30V power input, it is suitable for smart agriculture, automatic weather stations, road weather monitoring, solar farms, wind power sites, urban environmental monitoring, and remote IoT weather networks.
2. Product Overview
JW-XF400(YN20) compact weather station sensor is designed for multi-parameter outdoor weather monitoring where space, installation time, and maintenance cost matter. It integrates four key weather parameters into one device, allowing users to collect temperature, humidity, pressure, and rainfall data through a single digital communication interface.
The optical rainfall module detects raindrops on the sensor surface and calculates rainfall based on droplet size and quantity. Compared with traditional tipping bucket rain gauges, optical rainfall measurement has no moving parts and is more suitable for mobile monitoring, distributed stations, and unattended sites where mechanical maintenance is difficult.
The radiation shield structure helps reduce the influence of direct sunlight on temperature and humidity measurement, while the IP65 housing supports long-term operation in outdoor environments.
