![]() ![]() House shade problem: Doesn’t stay shady and the house has a thermal inertia. Examples of passive solar shielding would be putting the thermometer in the shade of the house, the shade of a tree, a solar shield made for the purpose. ![]() Solar shields come in two basic forms passive and active. While not a weather measuring tool itself, without a solar radiation shield, your temperature measurements will be junk if your thermometer is in direct sunlight. Silicone diodes can be included in a silicon integrated circuit.Īnother consideration is that infrared solar radiation will heat up anything left exposed to the Sun, including thermometers. The voltage through them changes with temperature. Thermistors change their electrical resistance as the temperature rises and falls so an increase or decrease in the voltage across a thermistor correlates with a rise or fall in temperature.Īnother common electronic thermometer uses silicon diodes. Thermistors are the most common electronic component used to measure temperature electrically. They produce a signal that is easy to digitize and transmit to an indoor display. These are not precision instruments but they are useful to see the temperature at a glance.Įlectronic thermometers are the most common type in digital home weather stations. These are commonly seen on porches and gardens.
