Best Indoor Humidity Monitor- Buyers’ Guide
Humidity monitors could not have come at a better time when we need them to assess the quality of our indoor space environment. Before you take home a device, it’s important that you have some hands-on information to help you make a good choice.
Additional Functions in an Indoor Humidity Monitor
Apart from measuring humidity and temperature, these devices also have extra functions such as:
- These units connect to a smartphone using Bluetooth. The readings are displayed using an app on the smartphone that receives information from the humidity monitor
- Time, Date, and Alarm Settings. If you would like the hygrometer to display the highs and lows after a set time, a device with an alarm helps to make that happen. The alarm also works for basic ringing to wake you up while the date settings display the daily calendar and even remembers the day and time when it is powered off.
What are you likely to see on a monitor when the humidity is 100 %?
When humidity hits 100%, it means the air is completely saturated. You will see a WET level on the monitor since any more cooling to the ambient air, and water droplets in the form of dew, mist or fog will be released to the ground.
What is the Most Comfortable Level of Humidity?
Every household produces moisture from exercising, bathing, cooking, washing and many others. Too high or too low humidity is not healthy.
If humidity is too high, you should install a dehumidifier or stop using a humidifier. You can also vent areas that bring in excess moisture like the bathroom. If humidity is too low, you should install a humidifier or keep houseplants.
Some Common Causes of High Humidity in the home
Leaky Windows. When using single pane windows, excess moisture is likely to get into your home. You will notice this by mold growing around the windows.
Poor Ventilation. If you live in environments where the air outside is relatively humid like in Houston, moisture can build up in the home leaving you in an uncomfortable environment. Heat and moisture can get trapped if there’s no means of escaping through vents and windows.
Excessive water use. Running the shower or dishwasher for extended periods, cooking and other applications of water can increase humidity levels tremendously.
Uses of Indoor Humidity Monitors
A baby’s room. A humidity monitor for the baby’s nursery helps to control the spread of flu and viruses and growth of mold in the room. A monitor helps to know when the levels are ideal between 30-50% according to Mayo Clinic.
Weed Growth. Indoor humidity for cannabis plants has to be optimal at their various levels of growth for healthy plants and good harvests. Too much moisture can lead to the growth of mildew, bud rot, and mold.
Clones need a humidity of 70%-80%; the vegetative stage needs 40%-60%, flowering needs 40%-50%, while final weeks of flowering need less than 40%.
Grow Rooms. Indoor gardens are affected by temperature and humidity. Farmers need to monitor humidity readings using a hygrometer to help identify the course of action. This can be to either increase the ventilation or use a humidifier to increase the humidity levels.
Music Instruments Room. A safe level of humidity is required for high-quality solid wood guitars since wood is not replaceable in a guitar and even in a piano. An ideal relative humidity level has to be controlled at around 50%. If you are a guitar retailer, you’ll want a device for your instruments if you wish to maintain the intended quality of the manufacturer.
Reptiles. Cool temperatures are just as important as proper humidity for reptiles and other amphibians. Humidity monitors will help you control their conditions. As a reptile owner, it’s vital that you know the ideal relative humidity for the kind of reptiles you keep. You can always consult with a local reptile’s expert if you have no idea about your particular pet.
Wood Room/Shop. Climate control is a must for wood storage and shops where you are selling wooden furniture like tables, chairs, bed frames, dressers, etc. Too much moisture causes wood to warp, rot, and crack over time. A humidity monitor will help sellers keep such storage spaces in optimum conditions.
Wine Cellars. Ideally, wine is stored in underground cellars in a corked glass bottle. Winemakers have to monitor the humidity level to create the ideal cool and damp environment for wine aging.
Water Activities. Indoor swimming pools and saunas release lots of evaporated water into the atmosphere. Since there’s no way to control evaporation, humidity monitors are paired with dehumidifiers to restore ideal relative humidity to prevent the destruction of walls and buildings.
How can you test the accuracy of a humidity monitor?
You can’t always accept results on a monitor because they look reasonable. Here’s how to test for accuracy in a humidity sensor. The saturated salt method is mostly used as it produces standard results.
You will need:
- A food storage bag
- A tiny cup the size of a bottle cap
- Little table salt
To measure Accuracy:
- Just make thick slurry by filling the cup with salt and adding water. Make sure not to dissolve the salt
- Now take the cup and humidity sensor and place them in the food bag
- Zip the food bag and store it for six hours
- After six hours read the results from the monitor
- An accurate humidity sensor will have a reading of 75%
How to Get Maximum Accuracy of a Humidity Monitor?
Many humidity monitors are sensitive to environmental conditions. Proper placement allows you to get the most accurate values. To do this, place the monitor in a dry and clean place. There should not be direct sunlight, heat sources, humidifiers or air vents.
Place the monitor one meter above the ground. Some of them come with a magnetic backing to stick on the refrigerator or other metal surfaces.
What is a Humidity Monitor Arduino?
If you have heard of such a monitor, then know, this is not a simple device. Arduino is a set that allows you to make a humidity monitor with your own hands. Included is the Arduino board and a set of sensors, including the Humidity sensor (DHT22). As a measuring system, it uses a capacitive sensor and a thermistor.
Following the instruction, you can connect the sensor to the Arduino board and program it through a special application. The Arduino set will be interesting to novice electronics engineers and programmers.
Hygrometer vs. Indoor Humidity Monitor
Hygrometers and humidity sensors are used interchangeably to mean the same thing. These are instruments that measure the relative humidity of indoor environments. But these words should not be confused with a humidistat which is used to actually control humidity.
Humidity Monitor for Android vs. Indoor Humidity Monitor
Humidity monitors for Android are mobile applications that help users get up-to-date readings of humidity around them by monitoring mobile device sensors and current environment parameters. They help the user know when to use a humidifier or a humidifier.
An indoor humidity monitor has humidity sensors that help the device to display correct readings in real time. They are more popular than Android Apps because of their high accuracy levels.
How Does a Humidity Monitor Work?
Humidity monitors measure moisture using different types of sensors. There are three basic types: capacitive, resistive and thermal.
Capacitive sensor consisting of a hygroscopic dielectric material. It is placed between a pair of electrodes. And we get a small capacitor. The dielectric material is plastic or polymer. Its dielectric constant ranges from 2 to 15. These values determine the capacity of the sensor when there is no moisture in it.
You can find these sensors in humidity monitors for ventilation and air conditioning systems, weather stations, cars, refrigerators, dryers, etc.
Resistive sensors are similar to capacitive sensors on the principle of operation. The relative humidity values are obtained by measuring the electrical change. These sensors use hygroscopic (moisture-absorbing) material. The difference is that the sensor measures the resistance of the material, not the capacitance.
This principle of reading information gives an advantage to resistive sensors. Its high surface capacitive allows to measure changes of the environment humidity up to 90% relative humidity at room temperature. But these systems don`t suitable to measure values below 5%.
You can often find home-use humidity monitors with resistive sensors. Their low cost makes them popular.
Thermal sensors are absolute humidity sensors (AH). They are really able to measure the absolute humidity of the environment. The working circuit consists of two thermistors that make up the bridge. These have negative temperature coefficients.
One thermistor is hermetically sealed in a chamber with a dry nitrogen. The second interacts with the open environment through small air vents. When the sensor is connected to electricity, it detects the resistance of the thermistors.
Thermal sensors are suitable for industry. They are built into drying chambers, incubators, food dehydration machines.
We cannot underestimate the importance of a good indoor humidity monitor. If you have concerns about levels of humidity in your home, recreational area, storage facility and the like, then you’ll want to invest in one of these top-rated brands.
We hope you can improve your current living conditions by employing a humidity monitor with the right procedures to correct poor humidity status.
Go on and start living a better life.
