The basics of deploying a weather station

Weather stations, like the HOBO RX3000 series, monitor environmental parameters such as temperature, wind speed, wind direction, rainfall, soil moisture, barometric pressure and photosynthetically-active radiation (PAR).

Moreover, their deployments are often located in harsh environments. Since weather stations monitor conditions 24/7 at a specific site, researchers can obtain precise measurements instead of making estimates based on regional weather data.

The following is a short guide on proper weather station deployment and safe practises. For a full, in-depth run-down on weather station deployment, please read the full guide here!


Understanding weather station components

A typical weather station consists of a data logger and sensors mounted on a metal tripod.

The system typically runs on battery power or a combination of solar power and a rechargeable battery.

Key components of a weather station include:

  • Data logger
  • Sensors
  • Cables
  • Tripod or other mounting system
  • Grounding
  • Securing equipment such as guy wires

Site locations and sensor placement
Weather station positioning

Some researchers need data on general weather conditions for an area. In these applications, researchers should place their weather stations in open, unobstructed locations. Buildings and trees can affect temperature, relative humidity, rainfall, wind speed, and wind direction. For this reason, weather stations should also be at a distance of at least ten times the height of nearby trees and buildings away from these obstructions.

Weather stations should be located at least ten times the height of nearby trees and buildings away from these obstructions.


Installing soil moisture sensors

Accurate soil moisture measurement probes need to have good contact with surrounding soil. Here are some tips to help with installation:

  • Install the sensor probes into undisturbed pebble-free soil.
  • For deeper soil moisture measurements, use a soil auger to dig a hole. Ideally this should be angled, so that the soil above the sensor is undisturbed. Then push probes into undisturbed soil at the bottom of the hole.
  • Use a PVC pipe with three slits made at 90-degree angles at the end of the pipe: two slits for the sensor and a longer slit for the cable.

After installing the sensor into the soil, partially backfill the hole, allowing soil to settle around the sensor. Pack the soil to the same density as the undisturbed soil. Then thoroughly water the soil around the sensor to cause the soil to fully settle around the sensor.


Configuring your weather station

While some data logging weather stations can be difficult to configure and often require the services of a professional system integrator for setup, today’s most advanced systems do not require programming or complex wiring. Instead, these systems leverage Smart Sensor technology, that provides the user with plug-and-play performance: once a sensor is plugged into the data logger, it is automatically recognized and can begin taking measurements. This type of system architecture can significantly reduce setup and deployment time, and reduce or eliminate the need for specialized integrator assistance.

Sensor cable protection

Lawn mowers, tractors, and chemicals can damage sensor cables. Moreover, rodents, birds, cattle, and other animals can bite, peck, or trample on sensor cables. For this reason, researchers often cover cables with conduit.

Proper grounding

Proper grounding of a weather station is advisable, as it provides protection from electrical interference and thus can help minimize the chance of system failures in the field.

Battery maintenance

As a general rule, replace rechargeable batteries every 3 to 5 years and regular batteries once a year. However, battery life depends on logging intervals. For example, with certain weather stations, if the logging interval is set at 1 second, the batteries last 30 to 50 days. If the interval is set at 1 minute, the batteries should last one year. Furthermore, make sure the batteries’ Use Before dates are at least two years from the current date.

Relative humidity, barometric pressure, wind direction and wind speed, and PAR sensors should be checked or calibrated annually.
