Frequently Asked Questions (FAQ)

Is there an app to check indoor humidity?

Generally, indoor humidity monitors measure humidity in the air. Some monitors also have a light and a temperature sensor. The best indoor humidity monitor in 2021 will measure humidity in your home and let you know if there is a problem or if you need to open a window. You can find an app that monitors indoor humidity at the Google Play Store or Apple App Store. Some of these monitors can be found on Amazon, eBay and other online retailers.

How do you monitor indoor humidity?

Just as you can monitor the humidity outside, you can track and measure the level of humidity inside your home. For obvious reasons, indoor humidity should be kept as low as is comfortable and possible, particularly during the cold months. Here are some of the most popular ways to track your home humidity levels.

What is the most accurate hygrometer?

It will depend on how you are using it. There are several types of hygrometers.

  • Analog hygrometers:
  • Digital hygrometers:
  • Hygrometer / thermometer combi units:

An analog hygrometer, also referred to as an ÔÇöclock-style' hygrometer, is made up of a geared mechanism and a dial or needle that moves along the face of the dial. This mechanism is moved by the changes in the moisture content of the surrounding air.

Although these devices are less expensive to manufacture, they also tend to be less reliable. Because of the gears and other moving parts, they have a higher potential for malfunction. The mechanism also tends to be very sensitive to temperature, so it is important to keep them away from areas that may have fluctuating or extreme temperatures.

Where is the best place to put a hygrometer?

You can determine the accuracy of the hygrometer by using a relative humidity chart (available from the manufacturer) that comes with the unit. Place it in the environment in question and observe the gauge. Compare the result to the chart. If it is too far off — regarding both humidity accuracy and temperature — stop using it because the readings are not accurate.

Next, consider placement.

Thick gauge or Non-Thick Gauge?

You have a choice when it comes to choosing the gauge your hygrometer will read from. A thick-gauge hygrometer reads humidity from the air directly around it. This prevents outside contamination from affecting the readings. It also prevents the humidity ramping up and down over time.

But it also means the hygrometer itself is more vulnerable and may be subject to more noise pollution.

Conclusion

Humidity is a vital component of comfort in our homes. It can keep family members at ease and also make them feel physically comfortable. It can also affect the quality of air, and as a result, your sanity and health. It might also be responsible for some of the allergies you face.

The good news is that you can now do something about it using smart devices. Humidity monitors can be very useful in ensuring that you maintain a healthy environment.
