Humidity meters, also known as hygrometers, are devices that are used to measure the amount of moisture in the air. Measuring the humidity in the air can be useful for a number of reasons, but here at OSERA we care about higher humidity because it helps our plants.
Many plants need higher humidity levels and there are lots of things we can do to increase the humidity such as misting our plants, placing them on pebble trays filled with water or even buying a humidifier. But if we don’t have a way of detecting the moisture level in the air, we can’t be sure that we are giving our plants sufficient humidity and there is also the possibility that we are giving them too much.
That’s where a hygrometer comes in. By detecting the humidity level in the air for us, we can then adjust our methods to make sure the quantity of water vapor in the air is optimal for our plants.
Hygrometers also go by the following names:
- Humidity sensor
- Humidity gauge
- Humidity monitor
- Humidity meter

Humidity Meter FAQ
Now we’ve hopefully helped you find the right humidity monitor let’s take a look at some of the most frequently asked questions regarding hygrometers to make sure you get the right humidity level in your home.
Is 70% humidity too high?
For some of your plants 70% humidity would not be considered too high and in face many tropical plants would thrive in these kind of conditions. But when humidity levels go above 70% it can start to become uncomfortable for a human being. So you may want to consider yourself when you’re planning the humidity levels in your house and not just think of your plants as tempting as that might be.
Is 25% humidity too low?
If humidity levels fall under 30% then your home will feel quite dry. This can affect your skin and hair but it can also have a bad effect on your plants. If you have a cactus or a succulent then they’re not going to mind but for many other plants you 25% humidity might just be a bit too low.
What is a good level indoors?
If you’re looking for an environment that is best for people and plants alike then you should be looking at a humidity level around 40 – 50%. Of course if you like things humid you might want to go higher than this or on the other hand maybe you’d rather your home be a bit drier. But for maximum comfort and skin benefits we would recommend your humidity levels to stay around 50%. You can use a hygrometer to monitor your humidity and adjust it accordingly.
What will happen if the humidity is high?
Too much humidity in your home can cause damage to it. High humidity can cause mould to grow which can be very dangerous to breathe in. If can also damage wallpaper and paint and some of your plants won’t do too well if humidity gets above a certain point. Use a humidity meter to measure the humidity in your home and try to keep it below 70%
What is the most accurate way to measure humidity?
The most accurate way to measure humidity would be to use a humidity sensor. With one of these you will be able to measure the amount of water vapour in the air and get a percentage reading of the humidity level. Some humidifiers now come with built in humidity sensors to help you know how humid your room is and you can set the device so that it produces more or less humidity depending on the level that you set it to.
Is a hygrometer the same thing as a humidity meter?
Yes they are the same thing, they just have different names.
