Handheld Meteorological Observation Instrument

1、Handheld Meteorological Observation Instrument Device Description

Handheld Meteorological Observation Instrument is specifically designed for localized, small-scale environments in farmland and grassland, enabling direct measurement of microclimate and soil conditions in the field.Handheld Meteorological Observation Instrument is an integrated handheld agricultural environment and meteorological multi-element monitoring terminal. It adopts industrial-grade precision sensors, intelligent processing chips, and a modular expansion architecture, specifically designed for modern agriculture (field fields/greenhouses/orchards/nurseries), forestry ecology, meteorology and environmental protection, water conservancy and hydrology, geological exploration, dryland water-saving irrigation, plant cultivation, scientific research and teaching, field emergency surveys, third-party testing, and soil surveys. It can simultaneously monitor 14 environmental parameters: 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. Integrating real-time measurement, local storage, wireless transmission, and cloud platform management, it meets the needs of mobile inspections, fixed-point observations, data traceability, and project acceptance. It features portability, durability, accurate measurement, strong expandability, and simple operation.
