Handheld Weather Monitor System

1、Handheld Weather Monitor System Device Description

Handheld Weather Monitor System 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 eight environmental parameters: air temperature, air humidity, light intensity, carbon dioxide, dew point temperature, photosynthetically active radiation, soil temperature, and soil moisture. Integrating real-time measurement and local storage, it meets the needs of various scenarios such as mobile inspection, fixed-point observation, data traceability, and project acceptance. It features portability, durability, accurate measurement, strong expandability, and simple operation.
