It also helps us plan the programs for a day in advance. We need a device that can do the job for us and that too with pinpoint accuracy. Most of the traditional thermometers that are used in homes are not high-end ones. You may have encountered the problem of inaccuracy or breaking easily. Also, these thermometers only give you the present temperature details, without keeping any record stored. On the other hand, we use various other applications to check the weather condition and temperature details. The problem with these applications is that these only give you the reading of a certain area due to which you fail to get the perfect report on the temperature of your place.

There are indoor outdoor thermometers that come with outdoor sensors that you can place outside. These sensors then send a wireless signal to the main unit, installed inside. Thus, the main unit shows you the reading- both outdoor and indoor. These thermometers are not any typical indoor/outdoor thermometer, but rather a complete home weather station. It’s accurate and has an extensive list of functions that impress even the biggest weather enthusiasts. One very alluring fact is that, unlike traditional thermometers at home, these indoor-outdoor thermometers do their job beyond just showing the temperature & humidity.

What Is A Thermometer?

A thermometer is a very basic device that we all use at the home daily. But when the question comes what is a thermometer, there’s always something more to know. 

A thermometer is, basically, an instrument that measures temperature. It can measure the temperature of solid things such as foods, a liquid such as water, or gas such as air. There are three measurement units for temperature: Celsius (℃), Fahrenheit (℉), and Kelvin (K). 

What Is A Thermometer?

The Indoor Outdoor Thermometer is a thermometer that gives you reading of the temperature of the indoor and outdoor of your house. These thermometers are very essential because it not only tells us the temperature update but forecasts the weather condition. 

The indoor thermometer tells us the indoor temperature details so that we can control the indoor temperature accordingly. On the other hand, the outdoor temperature details help us dress up according to the weather.

Types Of Indoor Outdoor Thermometers

There are a variety of thermometers available in the market. We have picked the mostly used ones on the list. 

  1. Glass Indoor Outdoor Thermometer

This is the most basic and widely used thermometer that you can find. These thermometers are also inexpensive and widely available. You might have seen this thermometer in any home or the garden, hanging. There is a temperature-sensitive liquid used in the glass that expands or contracts with the change of temperature. You would find a thin tube marked with temperature reading inside. You can read the temperature according to the level of the liquid. The problem with these thermometers is their accuracy. Ambient corrections are more difficult to achieve with this system and, in most cases, are not usually done. Therefore, it is not accurate as of the conventional precision thermometer. These thermometers, thus, are used for personal home purposes. 

  1. Wireless Thermometer

Wireless Indoor Outdoor thermometers are becoming more popular with the advancement of technology. Our list of best Indoor Outdoor Thermometer Reviews in 2020 has mainly talked about these thermometers. Coming to the point, wireless Indoor Outdoor Thermometers come with one main unit that has to be installed indoors and satellite sensors that you can place outdoor. The outdoor sensors then send temperature data to the main unit and thus you can read the temperature inside on the console. Some wireless thermometers even have LCDs on their satellite sensors as well. So, you don’t have to come indoor every time you want to check the temperature. These thermometers cost you more than the conventional ones but are more efficient and value for money. 

  1. Dial Thermometer

This is another common thermometer that you might have seen in many houses. Calling by the name, we can understand that it has something to do with dials. This thermometer works on the principle of a bimetal thermostat. It works when two metals expand and contract depending on the different rates when heated or cooled. One in-built needle is attached to the face of the dial that moves to show you the temperature reading. However, it can not measure any surface temperature. Analog dial type thermometers can be accurate but not always. These thermometers are very basic and usually have a longer lifespan

  1. Digital Thermometer

Digital indoor outdoor thermometers are also very popular. These thermometers come very cheaply as compared to the wireless ones. The thermometers use transistors to generate the process. Electricity flows through the transistor With the change of weather the flow increases or reduces accordingly. A converter then converts the flow into a temperature reading. Most digital thermometers also offer a backlight. The digital display is easy to read. You can also find different symbols indicating different weather conditions. It also shows you time and date.

  1. Weather Forecasting Indoor Outdoor Thermometer

This type of thermometers gives you more accurate reading as compared to the previous ones. The thermometers keep a record of weather change of past days and thus can forecast the weather condition of the next day. It reads data like humidity percentage, wind speed, the highest and lowest temperature of the day. This information gets stored in the main console that you can view anytime. 

  1. WiFi Indoor Outdoor Thermometer

If you want to read the temperature directly on your smartphone, then this is the type that you should consider. WiFi Indoor Outdoor thermometers use Wifi to send the temperature reading directly from the outdoor sensors to your smart device. It can be used for smart home integration. These thermometers are gradually dominating the market due to better accuracy with extra added features.

Why Do You Need An Indoor Outdoor Thermometer?

The importance of keeping track of weather conditions is beyond any description and would be very unjustified to discuss in some mere words. Although, this is one of the very basic questions that occur in our mind whenever we start thinking about thermometers. While keeping medical thermometers have vital importance, we must not overlook the fact that outside temperature plays a great role in our everyday life.

The main reason to have these thermometers is that you can get an accurate reading without leaving your home. But, for that why not the apps? Because the application that we are talking about can only give you temperature details of a certain area and not specifically of your home. Also, these are not accurate at all the time. 

Why Do You Need An Indoor Outdoor Thermometer?

Suppose you have a cold storage area in your home and you need to maintain the temperature there. These thermometers can do the job for you. Indoor Outdoor thermometers, in most cases, come with customizable alarms that you can set for the desired maximum and minimum temperature limits. When it goes over that limit, the alarm rings. You can use this thermometer to get accurate readings in a child’s room. Therefore, these thermometers are very useful to keep your daily life safe and planned.

Things To Consider Before Buying An Indoor Outdoor Thermometer

By now you may have understood how important a role these thermometers play in our daily lives. Buying just any indoor outdoor thermometer may not help you in your desired way. So,  we want you to go through it and understand all the factors that work while buying one. 

  1. Accuracy

A thermometer is credited mainly for its accuracy. The accuracy rating of indoor-outdoor thermometers are usually listed within a range, however, it still shows some margin of error such as +/- 2-degree Celsius. This much error is pretty negligible for someone who just wants to check the temperature. But, if you are someone who has more critical stuff like maintaining a greenhouse or pets cage, you might need thermometers that give you a more precise reading. 

  1. Display

While thermometers have to provide precise reading, we must not forget the importance of understanding the temperature reading, shown on the device. For this, displays play a huge role as the display is your primary interface with your wireless thermometer. Please make sure you choose a device that has a high-quality screen to avoid any frustration. Generally, the larger screens are better. Bigger screens can display information better and clearer than the smaller units. The brightness and contrast and viewing angle of the display play a huge role too. Especially when you mount it somewhere where it gets exposure to the sunlight. You can also consider the color screen for a better user interface.

  1. Barometric Pressure

Barometric pressure is the pressure caused by the weight of air above us. Air pressure generally affects the weather by influencing the movement of air around the world. More advanced indoor outdoor thermometers measure barometric pressure. Barometric pressure has a great role in depicting weather forecast. Higher barometric pressure area indicates that the air temperatures are lower and can bring blue skies while low-pressure areas generally develop clouds and precipitation. Barometric pressure has effects on arthritis and other bone and joint pain. This feature, therefore, helps to get a better and more accurate weather forecast.

  1. Transmission Range

The Indoor Outdoor Thermometers come with the main unit and satellite sensor/s. The sensors are connected wirelessly to the main unit. While mounted outside, these sensors then collect temperature data and send it to the main unit where you can see it. So, different thermometers have different transmission range. You would find a transmission range of 200-330 feet in most of the indoor outdoor thermometers. You can go for a higher range if you have a larger distance to cover. 

  1. Smart Home Integration

This is a feature that you can think of if you already have several smart devices at your home. Integrating your home with several sensors would make it simpler for you to control your thermometer just by commanding. For example, you might simply ask Alexa to update you about the temperature details and you would get it right away. However, smart home integration featured thermometers will cost you more. 

  1. Remote Monitoring

If you want to get the temperature update on your smartphone or laptop, you would need wifi-enables Indoor Outdoor thermometers. You can simply connect these thermometers via wifi and get the temperature reading from anywhere you want. However, this too is an extra feature and would surely cost you more. 

  1. Price

This is one of the most important sections that you must not overlook. The more features a thermometer consists, the more costly it becomes. Therefore, it is better to fix your budget at the very beginning and then go for choosing one.
