Understanding Weather Stations


What does a typical weather station include?

  • Anemometer (wind speed and direction)

  • Rain Gauge (daily rain collection and rainfall rate)

  • Temperature Sensor (outdoor and sometimes indoor)

  • Barometric Pressure Sensor

  • Humidity Sensor

What does each sensor or gauge do?

  • An Anemometer monitors wind direction and wind speed. Normally it involves a rotating tail to determine wind direction and a spin mechanism to measure the wind speed.

  • Temperature Sensor(s) most weather stations include an outdoor sensor and many also include an indoor sensor.

  • Barometric pressure sensor

  • Humidity sensor

  • Rain Gauge

Factors To Consider When Choosing a Weather Station or Instrument

Wired or Wireless


  1. Overall Accuracy of sensors and gauges

  2. Specific Accuracy of each sensor

Additional Sensors

  • Lightning detection

  • Leaf Wetness

  • Heated Rain Gauge

  • Additional temperature sensors

Ability to record and save data

  • Data Logging

  • Logging Capacity

  • How will the data be used?

  • Is a record of some or all instruments needed?

  • Is only the momentary reading important?

  • Is the data recorded by the sensors needed daily, weekly or monthly?

Installation time

  • Quick and Easy installation

  • No access to roof or dangerous roof

  • Need sensors mounted for the greatest accuracy


  • Stable or mobile

  • How mounted

  • Remote Use

  • Where to mount -On a pole, a rooftop, in a meadow, near trees, in the desert, on the top of a mountain, mounted on a moving vehicle (RVs, mobile weather stations, hurricane trackers)

Special Considerations sand, trees, extreme heat or cold
