Temperature+sensor+reads+too+high

Problem
Temperature reads too high (or inaccurate) when placed in the sun or close to a radiant heat source, like a house, building or structure.

 * 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 (see below FAQs) are very accurate. Inside your house, place a mercury thermometer next to the digital thermometer. the thermometers should agree within 2 degF.
 * 3) Place the sensor in a shaded area on the north side of the structure to avoid direct and radiant heat.
 * 4) Temperature sensors that do not have radiation shields will absorb solar energy and read higher then the ambient temperature. To prevent this problem, purchase a [|solar radiation shield]from Ambient Weather.
 * 5) If the problem persists, contact the manufacturer if it is in warranty (usually one year): Manufacturer Contact Information
 * 1) If it was purchased from Ambient Weather in the last year, please visit [|Returns & Exchanges]. We have a 30 day return policy and a one year warranty.

Frequently Asked Questions
> This is a poor method for comparing your temperature since you are in a different location and the reporting station may update only once per hour. In addition, sensor placement is very important. You will find the temperature on the north side of your house (mostly shade) is much cooler than the south side of your house (mostly sun). In addition, grass, trees, structures and houses and have a large impact on temperature. The National Weather Service requires very strict guidelines in installing sensors. However, they do not always follow their own guidelines. > Again, compare to a mercury thermometer (see above) in a shaded, well controlled area, like the inside of your house. > Digital thermometers use a temperature sensitive resistor. The electronics measure this resistance and it is converted to a temperature. All resistors have small variations which result in variations in temperature. It is impossible to integrate a mercury thermometer into a digital device. > There is a linear relationship between resistance and temperature within a specified range, and then becomes non-linear at the extremes. Thus, the accuracy can not be guaranteed at extreme conditions. Also, make sure you use lithium batteries in the remote sensor, which operates better during cold weather conditions. > [] > Remember to place the thermometer in the same location as the sensor and stabilize for a few hours. The sensor should be within the margin of accuracy.
 * 1) **My temperature reads different than an official weather station, like National Weather Service, Weather Channel, etc. Why is that?**
 * 1) **Why do digital thermometers have a margin of error** ( +/- 2 degF) **? If they are more expensive than a mercury thermometer, shouldn't they be more accurate?**
 * 1) **Can the temperature sensor be calibrated?**Only a few weather stations have calibration capability. They tend to be higher end weather stations with computer connectivity.
 * 2) **At the temperature extremes, my sensor is less accurate. Why is that?**
 * 1) **What is a red spirit thermometer?**They used to be called mercury thermometers, but mercury has been banned in many states, so red spirit with the density characteristics are used. Red Spirit Thermometers are very accurate. You can purchase them at most hardware stores for a few dollars. Here is an example on Amazon:
