Handheld Agricultural Meteorological Monitoring Instrument

1、Handheld Agricultural Meteorological Monitoring Instrument Device description

Handheld Agricultural Meteorological Monitoring Instrument consists of a handheld main unit and one or more integrated sensors, enabling real-time monitoring of multiple meteorological parameters in the agricultural environment.Handheld Agricultural Meteorological Monitoring Instrument is an integrated handheld agricultural environment and meteorological multi-element monitoring terminal, which adopts industrial-grade precision sensors + intelligent processing chips + modular expansion architecture. It is specially designed for modern agriculture (fields/greenhouses/orchards/nurseries), forestry ecology, meteorological environmental protection, water conservancy and hydrology, geological exploration, dry farming water-saving irrigation, plant cultivation, scientific research and teaching, field emergency survey, third-party testing and soil survey and other scenarios. It can simultaneously monitor 14 environmental parameters such as wind speed, wind direction, air temperature, air humidity, atmospheric pressure, rainfall, light intensity, carbon dioxide, dew point temperature, photosynthetically active radiation, soil temperature, soil moisture, soil salinity, and soil PH at one time. It integrates real-time measurement and local storage to meet the needs of all scenarios such as mobile inspections, fixed-point observations, data traceability, and project acceptance. It is portable and durable, has the characteristics of accurate measurement, strong scalability, and simple operation.
