Automatic Weather Station for Agriculture

The automatic weather station is tailored for smart farming. It tracks wind, temperature, rainfall and other key factors affecting crop growth. Users can also add sensors to monitor soil status and light conditions. It automatically collects and analyzes field data to help arrange irrigation and prevent crop diseases effectively.

 

 

The automatic weather station adopts durable casing with no movable parts, running steadily in hot, humid and dusty farm surroundings with little upkeep. We can adjust monitoring items to fit grains, fruits and tea crops for diverse planting scenarios. Specialized sensors capture precise data to work out accumulated temperature and crop water demand. Diverse signal outputs link smoothly with farm IoT systems for remote data viewing. It installs effortlessly and consumes tiny power, working sustainably with solar power across vast farmlands.

 

 

Each parameter is measured using a dedicated sensing principle optimized for agricultural field conditions:

Wind Speed & Wind Direction - Ultrasonic Technology Ultrasonic measurement delivers fast response and zero mechanical wear, accurately capturing field wind field variations to guide pesticide application timing and windbreak management.

Atmospheric Pressure - Piezoresistive Technology High accuracy and strong stability support weather trend assessment and agricultural production scheduling reference.

Temperature - Diode Junction Voltage Method Wide temperature range measurement with minimal error, precisely capturing diurnal temperature variation to guide sowing timing, frost protection, and heat stress management.

Humidity - Capacitive Sensor Wide measurement range suited to diverse humidity environments, accurately monitoring field air humidity for irrigation scheduling and pest and disease risk assessment.

Rainfall - Photoelectric Principle High interference resistance, accurately capturing precipitation data for integration with crop water demand estimates to guide irrigation scheduling and flood drainage management.

Solar Radiation - Photoelectric Effect Accurately measures solar irradiance intensity, combined with crop photosynthesis requirements to optimize planting management and supplemental lighting strategies.

Optional Expansion Parameters

• Soil Temperature - Capacitive
• Soil Moisture - Capacitive
• Soil Salinity - Conductivity
• Photosynthetically Active Radiation (PAR) - Photoelectric Effect

Open-Field Crop Production: Monitors weather conditions and soil parameters with ongoing automated processes across the broadacre (grain), vegetable, and fiber crop production areas to help with irrigation scheduling, fertilisation timing, early warning of pest and disease outbreaks and monitoring of crop development stages.

 

Protected Horticulture and Greenhouse Operations: Monitors temperature, relative humidity, solar radiation, and soil parameters inside greenhouse and polytunnel structures so that growers have access to accurate climate conditions for optimisation of climate control systems and for the management of protected crops.

The AI-written solution assists with orchard/fruit crop management through localised weather monitoring at the site of the orchard/fruit crop. The application assists in providing alerts on frost protection, determining the pesticide application window, and helps manage the quality of the fruit and predict yield, by utilizing temperature and radiation data.

 

Tea Garden Cultivation offers the ability to collect high resolution temperature, humidity, radiation and soil monitoring data that is critical to tea quality management, and the prediction of spring flush timing and extreme cold damage prevention in high value tea production.

Disaster Prevention and Agriculture Risk Management, includes Early Warning of Agriculture Disaster. Real-Time Monitoring of Weather Conditions in the Field allows for early detection of agriculture weather events (frost, heat stress, waterlogging, high wind) and corresponding protective measures to reduce losses due to damage from agriculture weather events.

 

 

Its field-oriented sensors stand up to dust and sharp temperature swings outdoors. Monitoring items can be customized for grain, fruits, tea and various planting modes. Optional soil sensors capture underground conditions alongside atmospheric data to guide precise irrigation. It calculates effective temperature and water demand to assist farming arrangement. The device runs steadily on solar power in remote farmland with no wired power supply. Rich signal interfaces connect seamlessly with mainstream agricultural IoT and control systems. IP66 waterproof and dustproof casing guarantees stable performance amid tough farm surroundings.
