Best Indoor Outdoor Thermometer – Buying Guide
There are several different options when buying the Indoor Outdoor Thermometer. Here is some important information you need to keep in mind when purchasing the thermometer.
What Are The Benefits Of Indoor Outdoor Thermometer?
There are several benefits of the indoor-outdoor thermometer. The first is the use of a single unit to know them inside and outside temperature. This is important as it reduces the number of devices you need.
Moreover, it is important to know the outside temperature if you are planning any outdoor activities. The temperature inside your house may be significantly different than the outdoor temperature.
These differences in temperature become more profound in the summer or winter season. As you may be using a heater or air conditioner to maintain a comfortable indoor temperature.
By knowing the outside temperature in advance can help you better plan the day. Getting outside to check the temperature may not give you a complete temperature sense as the body takes time to assess the temperature properly.
This is more so if you are going to be standing outside for a shorter duration to get a feel for the temperature.
Many indoor-outdoor thermometers also provide humidity level readings. This is important as it affects the temperature you feel despite the temperature you see on the thermometer.
People with medical conditions such as arthritis or joint pain are more sensitive to change in air pressure. By knowing all the information beforehand, you can better plan your day.
What Is Barometric Pressure And How It Relates To Temperature?
The barometric pressure is the pressure exerted by the air on the earth’s surface. The warm temperature makes the air lighter, and air rises far above the ground.
On the other hand, the lower temperature makes the air heavy. This is one of the reason that in the winter you see more fog or poor visibility as colder air stay closer to the ground.
In brief, a barometer measures the air pressure. High air pressure means cold temperature, and low air pressure means high temperature.
The use of barometric air pressure reading can help you forecast the coming change in temperature. The change in air pressure usually results in a gradual swing in the air temperature.
Types of Thermometer
There are several different types of a thermometer in the market. Some of the most common ones are:
Glass Indoor Outdoor Thermometer
The glass-based indoor outdoor thermometer is very basic and inexpensive. You may have seen it hanging in the garden or on the wall.
The glass contains a temperature-sensitive liquid solution. The inside liquid expands or contracts when the temperature changes. A thin tube inside the glass with a marked temperature tells you the temperature depending on the position of the liquid.
The temperature-sensitive liquid is in the form of a eutectic alloy consisting of gallium-indium-tin. It is also known as Galinstan and uses a mixture such as mercury, alcohol, or toluene.
Digital Indoor Outdoor Thermometer
The digital thermometer uses transistors to measure the temperature. The transistor controls the flow of electricity. When the temperature changes, it changes the conductivity of the thermometer, which reduces the current flow. A converter then changes the current into a temperature reading.
You need either battery or some other type of power source such as an electrical outlet or solar lights to power the device.
Analog Indoor Outdoor Thermometer
The analog indoor outdoor thermometer is also known as dial based thermometer. It uses two metal pieces that contract or expand based on the temperature.
A needle is attached to the metal which moves at the change of the length of the metallic bar. This is a very basic and durable thermometer, but the downside is that it does not provide a very accurate temperature.
Wireless Indoor Outdoor Thermometer
The wireless thermometer contains two units, the host and the beamer. You can place the beamer wherever you want the temperature to be taken. The temperature signal is sent wirelessly to the host, which displays the temperature.
The wireless ability of the thermometer allows you to have more flexibility as you can place it wherever you need. Some of these devices can exceed over 100 feet, which means longer outdoor reach for the temperature reading.
Wifi Indoor Outdoor Thermometer
The wifi indoor outdoor thermometer sends the temperature reading directly to your smartphone.
Some makers of wifi thermometers allow you to pair your thermometer with your home cooling or heating system.
This allows you more control over the temperature inside your home as you can monitor and control it remotely.
What Features To Look For In The Best Indoor Outdoor Thermometer
The thermometers available in the market contain several features which you may or may not need. It is important that you identify your needs first and then look for the features of the thermometer.
Here are some useful features to look for in the thermometer.
Temperature Accuracy
Most of the residential use thermometer gives you a fairly accurate temperature reading. But it still contains some margin of error such as +/- 2-degree Celsius.
It may not be a big issue for many people who are using these thermometers to check the weather or to decide how much dress-up they need.
But for many others who are using the thermometer for more critical stuff such as controlling the temperature in the greenhouse, pets cage, and food storage may need more precise control on the temperature reading.
Display
The display of the thermometer is an important consideration when you are looking to buy an indoor-outdoor thermometer. A small display makes it difficult to read and could result in reading the wrong temperature.
This is why we recommend the display size of temperature reading to be big and easier to read.
If you are using a digital display thermometer, then some models have a backlight on display. The backlight makes it easier to read the temperature in low light or in the dark.
Ease of Use
The best indoor outdoor thermometer should be easy to use to get the information you need. A device that needs constant calibration or has to go through several different calibrations will not be very helpful in the long run.
Wireless Capability
We consider the wireless capability to be an important feature to have. After all, who wants to do things manually these days. The wireless capability allows you to get indoor and outdoor temperatures remotely without you running any wire through it.
But as usual, the more feature you will have, the more it will cost and the more complex it becomes. So there is a bit trade-off.
Now, based on your needs, you may not want a wireless capability. But this is something you should consider when looking at a thermometer.
Temperature Scale
Do you want your temperature readings to display in Fahrenheit or Celsius?
Depending on whether your country has adopted the imperial or metric system, you may prefer one type of reading more than the other.
Many thermometers provide you with the temperature in both scales, and you can easily change it through its settings. If you live in the United States, you may prefer reading in Fahrenheit, but if you live in Canada or Europe, then Celsius will be more prevalent.
Regardless of the place where you live, you should be able to choose the temperature readings, which is more convenient and easier for you to understand.
You don’t want to keep converting one unit into another. It becomes frustrating if your thermometer does not display a temperature reading which you are comfortable with.
Power Source
Digital thermometers need a power source to operate. The power source can be either through a battery or through a power outlet. Some thermometer uses solar lights to charge the battery.
The battery-powered thermometers are more portable as you can place them wherever you need them. But as a downside, you have to replace the batteries regularly or use a rechargeable one.
The power outlet operated thermometer works by using electricity from your home power outlet. It is less flexible but needs less work as long as you provide it with an uninterrupted power supply.
For the best indoor outdoor thermometer, we recommend a thermometer, which allows you to choose both types of power sources.
Display Size
Depending on the place where you plan to use the thermometer, the display size may be an important factor.
If you plan to use it in the office or in some narrow space, then choose a compact display size. Whereas if you want to hang it on the wall and see it from a distance, then a bigger display size is more preferable.
Display Color
This is not essential, but some people find it helpful to have a colored display to show the temperature reading. For example, the closer to the red color indicates the warm weather.
The colored display is more expensive than the monochromatic color displays and consumes more power.
This may be an issue if the thermometer uses a battery. But if you don’t have any of those constraints, then the color display can be quite helpful and looks appealing.
Multi-Function
You may want the thermometer to be multi-functional, so you may not use it only to look for the temperature.
Advance thermometers come with several other sensors and functionalities. The most common ones are the display of time and date, weather forecast, or barometric pressure.
How Accurate is The Indoor Outdoor Thermometer?
The accuracy of a thermometer depends on the type of thermometer and its placement. The placement is far important than the type. Many people don’t give any thinking when finding a location to place their thermometer.
Choosing the right location will give you a reasonable temperature range which may vary in between +/- 2-degree Celsius range. This should be good enough for most of the residential use.
But if you are doing a temperature-sensitive project or need a highly accurate temperature, then you need to buy a well-calibrated thermometer. These are more expensive but can provide up to 99% temperature accuracy.
Where is the Best Place To Mount Indoor Outdoor Thermometer?
The placing of the thermometer greatly affects the temperature reading. For outdoor placements, choose a shaded location. The location should not get direct sunlight or other artificial heat sources. So, make sure that you don’t place the sensor closer to heat vents or near a fire pit.
It is ideal to place the sensors near the shaded open area location. This is where professional weather forecasters place their thermometers. Sometimes you have to test the area and check if you are getting the correct temperature reading.
Don’t place the sensor right on the ground but keep it 6 to 7 feet above the ground. By placing sensors too close to the ground, the ground temperature affects the temperature reading.
Try moving your sensor to a different location if you do not get an accurate reading at one place. You can hang the sensor or attach it to poles, trees, fences, or any tall object.
There are optional temperature and humidity solar radiation shield that provides shade from sunlight and allow airflow through the shield. This helps you get a more accurate temperature reading.
