Handheld Weather Monitor System

1、Handheld Weather Monitor System Device Description

Handheld Weather Monitor System provides accurate measurements of air temperature, air humidity, light intensity, carbon dioxide, dew point temperature, photosynthetically active radiation, soil temperature, and soil moisture.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.
