 Technical Analysis and Application Guide for Weather Monitoring Stations and Weather Monitors 

 I. Definition of Weather Monitoring Stations and Weather Monitors 

A weather monitoring station is an integrated system designed for systematic observation of key atmospheric parameters, including temperature, humidity, atmospheric pressure, wind speed, wind direction, precipitation, and light intensity. Through long-term, continuous data collection, it reflects regional climate characteristics and provides scientific basis for weather forecasting, disaster early warning, agricultural production, transportation management, scientific research, and environmental protection. 

A weather monitor is the core measurement unit within the station, responsible for single- or multi-point meteorological data acquisition and transmission. Modern weather monitors integrate high-precision sensors and data processing modules, supporting multiple signal outputs and remote communication protocols, laying the foundation for automated and intelligent meteorological monitoring.

 II. Working Principles of Weather Monitoring Stations and Monitors 

The operation relies on the coordinated functioning of multiple sensors: 

1. Temperature & Humidity Sensors: Detect changes using resistance, capacitance, or semiconductor elements, converting physical quantities into electrical signals.

2. Atmospheric Pressure Sensors: Measure pressure via piezoresistive, capacitive, or MEMS technology.

3. Wind Speed & Direction Sensors: Mechanical types use rotating cups and vanes; ultrasonic types calculate wind parameters from sonic pulse travel-time differences.

4. Precipitation Sensors: Commonly tipping bucket, optical scattering, or weighing methods.

5. Light Intensity Sensors: Employ photodiodes or photoresistors.

6. Soil Moisture Sensors: Capacitive or resistive sensors measure soil dielectric constant or impedance to determine volumetric water content.

7. Data Acquisition & Transmission Module: Aggregates sensor data and transmits via wired or wireless channels to monitoring terminals or cloud platforms. 

In principle, weather monitoring stations ensure synchronization and high accuracy across multiple parameters through coordinated multi-sensor acquisition.
