To get the most accurate readings, keep the sensor away from heat sources like chimneys or air conditioning units, as well as out of direct sunlight. The temperature sensor should be about 4-5 feet from the ground. If possible, keep it at least 50 feet away from bodies of water and trees to ensure the humidity readings aren’t compromised. Place the anemometer, which measures wind speed, as high as possible—ideally at least 7 feet above all surrounding structures. Finally, set your home weather station on grass or short bushes or shrubs. Avoid asphalt or concrete as these types of surfaces can impact the readings.
