Applications
Meteorology
Wind, rainfall, temperature, relative humidity, pressure and radiation, from a compact station to a full network.
A weather station combines sensors, a data logger that stores the readings and a way to send them. This guide helps you match the three to your site.
The problem
Weather changes from place to place: the rain in the next town is not the rain on your field. Irrigation, solar plants, highways and research need on-site measurements, recorded continuously by sensors that can take sun, rain and cold.
The variables
- Wind: speed and direction, from ultrasonic anemometers
- Precipitation: tipping-bucket and weighing rain gauges, rain, snow and hail detectors
- Temperature, relative humidity, pressure and dew point
- Global and diffuse solar radiation, PAR and UV light
- Visibility and evapotranspiration
How to choose
A compact station with everything in one body, or separate sensors wired to a data logger. Data can travel over cellular, Wi-Fi, Sigfox, satellite, LoRaWAN or radio. Sensors with SDI-12 or Modbus output plug into loggers already in the field. Away from the grid, use a solar panel; in the cold, heated versions. Silicon pyranometers respond faster; thermopile ones are more accurate. Some loggers send alerts by email or SMS.
