Why You Should Measure Indoor Humidity Too
Many people buy an indoor thermometer but ignore humidity.
That is a mistake because two rooms with the same temperature can feel very different depending on humidity.
For example, 75°F can feel comfortable or uncomfortable depending on the amount of moisture in the air.
High Humidity Can Cause Problems
- Rooms may feel warmer
- Condensation can increase
- Mold risk can increase
- Basements may become damp
Very Low Humidity Can Also Be Uncomfortable
- Dry skin
- Static electricity
- Dry throat
- Wood furniture can be affected
Buying Tip: For most homes, choose a thermometer that also includes a hygrometer.
Indoor Thermometer vs Indoor Hygrometer
| Device | Measures |
|---|---|
| Thermometer | Temperature |
| Hygrometer | Humidity |
| Thermometer + Hygrometer | Temperature and Humidity |
Most modern indoor monitoring devices combine both sensors.
How Accurate Should an Indoor Thermometer Be?
Accuracy is one of the most important specifications when buying an indoor thermometer.
However, you should understand the difference between:
- Accuracy
- Resolution
Accuracy
Accuracy describes how close the measurement is to the actual temperature.
Resolution
Resolution describes the smallest change the display can show.
A thermometer can display temperature in increments of 0.1°F but still have a larger measurement error.
More decimal places do not automatically mean higher accuracy.
Where Should You Put an Indoor Thermometer?
Placement can significantly affect the reading.
Avoid Placing It:
- In direct sunlight
- Next to a heater
- Near an air-conditioning vent
- Above a stove
- Near electronics that produce heat
Better Locations Include:
- Interior wall
- Central part of the room
- Area with normal airflow
- Away from direct heat sources
Give the device time to adjust after moving it to a new location.
