In the era of precision agriculture, accurate and continuous environmental data is the foundation for efficient farming decisions. The WS650 All-in-One Weather Station by THEATA Instruments provides a comprehensive meteorological monitoring solution tailored for modern agricultural applications — from crop growth monitoring to smart irrigation and greenhouse management.

Comprehensive Meteorological Monitoring

The WS650 integrates seven essential parameters in one compact sensor:

• Wind speed and direction – high-accuracy ultrasonic measurement ensures reliable wind monitoring for spraying and greenhouse ventilation control.

• Temperature and relative humidity – essential for crop growth models, disease prediction, and post-harvest management.

• Barometric pressure – provides vital reference data for regional weather forecasting and microclimate modeling.

• Precipitation – supports intelligent irrigation systems and helps assess field water balance.

• Solar radiation – enables calculation of evapotranspiration (ET) and photosynthetically active radiation (PAR) for optimizing irrigation and fertilizer strategies.

Each WS650 unit delivers high precision and stability, with temperature accuracy up to ±0.3 °C (optional) and humidity accuracy of ±3% RH, ensuring trustworthy data even under challenging field conditions.

Designed for Harsh Agricultural Environments

With a durable IP66-rated housing, the WS650 withstands rain, dust, and temperature extremes from -40 °C to +70 °C.
Its optional heating function ensures accurate measurements in cold or frost-prone regions — ideal for agricultural operations in mountainous or temperate zones.

The all-in-one compact design minimizes installation space and maintenance effort, making it suitable for both fixed stations and mobile agricultural monitoring units. The low weight (0.6 kg) and simple mounting process further reduce setup costs for system integrators and dealers.

Flexible Integration and Communication

The WS650 supports multiple analog and digital interfaces, including RS-485 (default), RS-232, RS-422, and SDI-12, along with MODBUS and NMEA communication protocols.
This flexibility allows seamless integration into data loggers, IoT gateways, or existing agricultural monitoring platforms.

Analog outputs (4–20 mA, 1–5 V) enable direct connection to control systems such as automated irrigation controllers or greenhouse management systems. This open architecture makes WS650 a highly compatible choice for equipment manufacturers and system integrators.

Applications in Modern Agriculture

• Smart Irrigation Systems: Combine precipitation, temperature, humidity, and solar radiation data to automatically adjust irrigation schedules and reduce water waste.

• Greenhouse Climate Control: Use real-time wind, temperature, and humidity data to regulate ventilation, heating, and CO₂ levels.

• Crop Growth and Disease Modeling: Improve prediction accuracy for crop diseases and pest outbreaks based on localized weather data.

• Agricultural Research and Field Trials: Support data-driven experiments requiring continuous, multi-parameter environmental monitoring.

Cost-Effective, Reliable, and Easy to Deploy

Thanks to its compact all-in-one structure, the WS650 reduces both installation complexity and maintenance cost, compared to multi-sensor configurations.
This makes it an ideal solution for large-scale deployments across farms, agricultural research stations, and environmental monitoring networks.

The WS650 All-in-One Weather Station empowers farmers, agronomists, and agricultural technology providers to make smarter, data-driven decisions — helping improve crop yield, resource efficiency, and sustainability.
