Why Sensor Siting Matters

Even the best home weather stations will give poor readings if their sensors are not placed correctly.
Good siting ensures that your measurements truly reflect the weather in your location—not heat from your driveway or shade from your neighbor’s fence.

Full Sensor Siting Checklist

• Place temperature/humidity sensors 5–6 feet above grass or natural surface.
• Keep sensors at least 50 feet from large paved areas, buildings, or heat sources.
• Use proper radiation shielding for temperature sensors.
• Mount wind sensors 33 feet (10 m) above ground, free from obstructions.
• Rain gauges should be level and unobstructed, 2–5 feet above the ground.
• Solar radiation sensors must have full sun exposure from sunrise to sunset.
• Keep sensors clear of trees, fences, or buildings that block airflow or sunlight.
• Secure mounts firmly to prevent vibration and movement.
• Check sensor placement twice a year for changes in surroundings.
• Follow manufacturer’s recommendations for cable length and positioning.

Extra Tips for Each Sensor Type

Temperature & Humidity Sensors

Use a ventilated radiation shield and avoid mounting over concrete or asphalt.

Wind Sensors

If you can’t reach the ideal 33-foot height, mount as high as possible and note the reduced accuracy.

Rain Gauges

Level them with a spirit level, and keep away from obstructions that block rain on windy days.

Solar Radiation Sensors

Keep away from shaded areas and reflective surfaces that may distort readings.

FAQs

Why is sensor siting important for weather stations?

Correct siting ensures your data reflects actual environmental conditions without interference.

How high should I mount temperature and humidity sensors?

Mount 5–6 feet above grass in a shaded, ventilated spot.

Where should I place wind sensors for accurate readings?

Mount at least 33 feet above ground on a clear mast.

Can I mount a rain gauge on my roof?

No, wind turbulence can distort rainfall data—keep them low and level.

What is the best location for a solar radiation sensor?

Choose a spot with full sun from sunrise to sunset.
