Ambient Weather Support

Temperature Reads Too Low At Night.

Temperature can read too low (or inaccurate) at night when placed close to a radiant heat source, like a house, building or structure.  It can also read lower then other stations in your area due to irrigation or sprinklers.

  1. Place the sensor inside next to the indoor console sensor. Wait about 1 hour for stabilization. The sensors should agree within the accuracy specifications. Most RTD (resistive thermal device) sensors are accurate within +/- 2 degF. Thus, the sensors should agree within 4 degF.
  2. Mercury or red spirit thermometers are very accurate. Inside your house, place a red spirit thermometer next to the digital thermometer. The thermometers should agree within 2 degF.
  3. For colder temperature verification, place the sensor with the red spirit thermometer in the regrigerator or freezer.
  4. If the sensor is separate, place the sensor in a shaded area on the north side of the structure to avoid direct and radiant heat.
  5. Temperature sensors that do not have radiation shields will absorb solar energy and read higher than the ambient temperature. To prevent this problem, purchase a solar radiation shield from Ambient Weather.
  6. We have a one year warranty and a 30 day return policy. For details, please visit:
