WUHAN, China – Wuhan Chenyun Technology Co., Ltd. (brand: YIGU), a manufacturer of meteorological and environmental monitoring equipment, has deployed its compact weather stations across vineyard and ranch properties in California’s Central Valley. The systems provide real-time microclimate data to support frost protection, irrigation scheduling, pasture management, and crop planning.

The Central Valley is one of California’s most productive agricultural regions, with extensive vineyards, orchards, and irrigated pastures. The region’s Mediterranean climate—hot, dry summers and cool, wet winters—creates variability in temperature, rainfall, and humidity across relatively short distances. This spatial variability makes localized weather data essential for precision agriculture. Regional forecasts often fail to capture conditions at the individual block or field level.

The Chenyun compact weather station addresses this gap with a small-form-factor, low-power sensor suite that can be deployed across multiple locations within a single property, building a dense network of microclimate monitoring points.

System Configuration and Specifications

The Chenyun compact weather station deployed in California is a lightweight, integrated sensor unit weighing 240 grams. The system supports multiple sensor configurations based on site requirements.

Standard sensor options include:

• Wind speed – Range: 0–45 m/s; accuracy: ±(0.5+0.02V) m/s; resolution: 0.1 m/s; start-up threshold: ≤0.8 m/s

• Wind direction – Range: 0–359°; accuracy: ±3°; resolution: 1°

• Air temperature – Range: -40°C to 80°C; accuracy: ±0.3°C; resolution: 0.1°C

• Relative humidity – Range: 0–100% RH; accuracy: ±5% RH; resolution: 0.1% RH

• Atmospheric pressure – Range: 300–1100 hPa; accuracy: ±0.5 hPa (at 25°C); resolution: 0.1 hPa

💡Additional optional modules include soil moisture sensors and crop disease warning modules.

Power and communication:

• Total sensor power consumption: <150 mW
• Power input: DC 5V or DC 9–30V; solar panel compatible for remote installations
• Communication: RS485 (Modbus-RTU), RS232 (Modbus-RTU), or TTL (Modbus-RTU)
• Cable length: 2 meters standard (custom lengths available)
• Operating environment: 0–100% RH, -40°C to +60°C
• Ingress protection: IP64
• Weight: 240 g

Function

The system collects real‑time meteorological data including wind speed, wind direction, temperature, humidity, rainfall, and solar radiation. It is expandable with optional modules for soil moisture monitoring and crop disease early warning.

Transmission

Data is uploaded to the cloud via network connections. Users can remotely view and analyze data through web interfaces and mobile applications, and trigger automated irrigation or equipment control commands.

System Advantages

• Remote Monitoring – View real‑time data via mobile app or web portal without on‑site inspections.

• Low‑Power Design – Suitable for remote farmland or pastures, with extended maintenance intervals.

• Customizable Alerts – Set threshold‑based alarms (e.g., high temperature, heavy rainfall, frost) for timely response to adverse weather conditions.

Installation and Site Adaptability

The compact form factor and low weight allow flexible installation options. Units can be pole-mounted at multiple points across a property, creating a monitoring network that captures spatial variability in temperature, humidity, and wind conditions.

The system is designed for low-maintenance operation in remote agricultural settings. Total sensor power consumption under 150 mW enables solar-powered deployment, eliminating the need for grid connections or frequent battery changes. The IP64 enclosure provides protection against dust and water ingress, suitable for field conditions.

Application Scenarios

Primarily deployed in vineyards, pastures, and orchards. The system supports irrigation optimization, frost prevention, and crop growth cycle assessment—a typical application in smart agriculture.

Case 1: Vineyard Frost Warning

The system continuously monitors air temperature and wind speed during nighttime hours. When temperature approaches 0°C and wind speed drops to very low levels, it automatically triggers an alert, notifying growers to activate fans or heaters to protect grape buds from frost damage.

Historical data can be analyzed to identify frost cycles, supporting variety selection and planting layout optimization.

Case 2: Pasture and Forage Management

By combining rainfall, soil moisture, and temperature data, the system predicts forage growth rates. This information supports rotational grazing planning, preventing overgrazing and pasture degradation.

During dry periods, precise data enables targeted irrigation to maintain forage production.

Case 3: Automated Irrigation

The system calculates crop water requirements based on temperature, humidity, solar radiation, and soil moisture data. It automatically controls valves or pumps to deliver on‑demand irrigation, reducing water consumption by 30% or more while improving fruit quality.
