Handheld agricultural monitoring instrument

1、Handheld agricultural monitoring instrument Device Description

Handheld agricultural monitoring instrument is used to monitor 16 environmental parameters, including wind speed, wind direction, air temperature, air humidity, atmospheric pressure, rainfall, light intensity, and carbon dioxide.Handheld agricultural monitoring 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 16 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, soil pH, total radiation, and leaf surface temperature. 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 across all scenarios. It features portability, durability, accurate measurement, strong expandability, and ease of operation.
