Local climate data for farms and field research

Weather stations and field sensors measure the microclimate around crops, greenhouses and research plots. Fixed solar-powered stations log temperature, humidity, rainfall, wind, illumination and radiation continuously, and several models upload readings over the mobile network to a cloud platform with alarms for abnormal values. Handheld monitors and recorders accept interchangeable sensors for CO2, PAR, soil moisture, salinity and temperature, so one logger can serve many sites. Agricultural research centres, universities, extension services, irrigation projects, greenhouses and large farms use these systems. ASFAN supplies, installs and supports weather equipment and helps specify field monitoring networks.

ASFAN supplies and supports agricultural weather stations and field sensors for farms, research centres and agencies across Saudi Arabia.

Irrigation scheduling

Temperature, humidity, wind and radiation data allow evapotranspiration to be estimated, so irrigation volumes follow real crop water demand and scarce water is not wasted.

Disease and pest risk

Humidity, rainfall and temperature patterns drive many plant diseases and insect life cycles, so local weather records support timely warnings and preventive action.

Field trial records

Research plots need documented weather conditions to interpret results, compare seasons and sites, and meet the reporting expectations of scientific publications and funding programmes.

Greenhouse and site checks

Handheld monitors with interchangeable sensors let staff check CO2, light, PAR and soil conditions across greenhouses and fields without installing a fixed station everywhere.

Frequently Asked Questions

Can the stations run without mains electricity?

Yes. The fixed stations offered are solar powered with internal batteries, and the handheld recorders use rechargeable lithium batteries, so they suit remote fields and research sites without a power supply.

How is weather data retrieved?

Depending on the model, data is stored on an SD or TF card for download, shown on a built-in display, or uploaded over the mobile network to a cloud platform and phone app for remote viewing.

Can additional sensors be added later?

Several stations are modular. The small fixed station accepts up to 32 sensors, including soil pH, EC, moisture and temperature, so a network can begin with core weather parameters and expand as needs grow.
