One of the biggest problems you might be facing is the need to closely monitor the temperature and humidity of your properties and possessions to keep them from getting damaged.

The technology has, however, come to your rescue. The introduction of the wifi thermometer enables you to remotely receive temperature and humidity alerts via the internet connection—anywhere, anytime. This helps take preventive measures to prevent costly and irreplaceable damages to your valuables when these conditions go extreme.

That said, we’ve researched what makes the best wifi thermometer. And in this post, we’ll be sharing with you all our findings to help you choose the best model for your unique needs.

(We’ve also researched the 10 top-rated wifi thermometers and room temperature apps on the market today, which we’ll review for you below).

What Are Wifi Temperature Sensors?

Wifi temperature sensors are compact devices designed to wirelessly transmit REAL-TIME temperature (and sometimes humidity) readings, over the internet, via a cellular network, or Bluetooth. The devices come with mobile apps that you install in your smartphone to enable you to receive the alerts from any location and at any time.

As you already know, keeping a tab on these two conditions (temperature and humidity) is crucial for your home as well as businesses. If they go beyond or below the optimal levels, they can result in costly or irreplaceable damages to your properties and possessions. Even worse, they can affect the health of your family.

(we’ll discuss the many uses/applications of these devices later on; keep the tab open!)

That being said, these devices come designed to help you monitor these conditions, without being physically there. This will help you take preventive measures on time to prevent possible damages.

These ingenious devices are quite affordable and extremely easy to operate—making them accessible to everybody. You can also choose to receive alerts from wifi temperature sensors on your smartphone, computer or tablet as long as there’s an internet connection.

Currently, the market is flooded with temperature sensors of all sorts. And if you’re not careful which one you choose, you can end up with a cheaply made, unreliable product that’ll hardly fit your specific needs.

What To Look For Before Buying One?

There’s always a cloud of confusion that sets in when you’re trying to buy a new product for the first time. You want to make sure you don’t make a mistake that can lead to the wrong choice.

When it comes to buying a new wifi thermometer, it’s no different.

Knowing how to choose the right model for your needs will help take home a device that meets all your temperature and humidity tracking needs.

Below, we walk you through the things that matter when it comes to choosing a remote temperature sensor:

Type of Connectivity

As we’ve seen from the 10 products above, different remote sensors come with different types of connectivity. Which connectivity to choose will depend on your specific needs.

wireless thermometer connection type

Here’s a rundown of the most common connectivity options you’ll get with these sensors:

  • Wi-Fi: this is the most popular type of connectivity for most applications. It’s highly reliable and enables you to monitor your sensor from just anywhere, anytime.

  • Bluetooth: this type of connectivity will limit the transmission range (operate within the Bluetooth range), meaning you might not be able to receive the alerts if you move out of home.

  • Radio-based wireless signals (433MHz): in most cases, this connectivity requires you to invest in a gateway device to remotely view the recorded data on the internet. Lack of a clear line of sight might distract the signal.

  • Cellular-based network: this type of connectivity is loved due to the excellent range it offers, facilitating true remote viewing. Unfortunately, huge subscription costs are involved with this service.

Where possible, we recommend you to go for the Wi-Fi-based temperature sensors.


You’ll also need to ensure that the monitoring system you’re buying records accurate data. This will ensure you receive the correct data that helps you safeguard your properties, temperature-sensitive creatures, etc.

Two things will help you determine the accuracy of a given device: the temperature and humidity range (the wider the range, the better) and the degree of accuracy.

A device with a temperature range of -40°F-125°F (accurate to ±0.4°C (max)) and a humidity range of 0-100% (accurate to±4% RH (max)) will be able to provide you with accurate readings.

A sensor with even better specification than the above will mean greater accuracy.

Power source

As we’ve seen in the products we’ve reviewed above, most models run on different types of batteries…while a few models require to be plugged in.

The best power source for you will directly depend on your specific needs. For instance, if you want a sensor that you want to place on your vacation home (which is far away from your home), you should go for a battery with a longer lifespan (say 6-12 months) since you’ll not always be there to replace it.

The power outage will also affect the portability of the sensing device. A wifi thermometer that’s battery powered is the best option if you’re looking for portability.

TIP: If you plan to use your remote sensor in areas with extreme climates, we suggest that you choose lithium over alkaline batteries as they perform better.


This is a crucial factor to consider for those who wish to monitor more than one location using a single remote sensor.

The best example is a homeowner who wants to continually monitor the temperature and humidity of various locations around their home—like the basement, fridge/freezer, outdoor temperatures, laundry room & bathrooms (for leak detection), etc.

In such cases, you’ll need to look for a device that allows you to easily add an extra sensor for each location. And then monitor all of them from your smartphone, tablet, or laptop.


We also suggest that you come up with a budget of the amount of cash you’re willing to spend on the new remote sensor device.

One thing we can all agree on is that the most accurate, reliable monitoring system with impressive features will cost you a lot of cash.

But again, you don’t have to worry about spending too much on the high-end models if you’re facing hard economic times. From our list of top recommendations, we have reviewed some highly affordable models that deliver accurate results and will meet most of your needs and expectations.

BEWARE: Some companies tend to impose hidden costs on their products, in terms of subscription fee. We advise you against buying a sensor that charges any subscription fee for their App as most of them are 100% FREE.

What Are The Uses Of These Products?

There are more uses of the remote temperature monitoring device than you can imagine.

In this section, we’ll outline the most common uses of a wifi thermometer:

Refrigerators and Freezers

Probably one of the most common applications of remote temperature monitoring systems in most homes and businesses is the refrigerators and freezers.

In homes, there’s a long list of foods that must be stored within specific temperatures, below or above which they become unsuitable for human consumption. The same case applies to commercial settings dealing with perishable foods; if the foods get damaged, the owner will count huge losses which might lower their businesses.

Using a wifi thermometer in such scenarios will help you remotely track the temperature of your foods, ensuring the safety of your investment.

Pet Monitoring

Another way in which a wireless temperature sensor can be of help to you is that it can keep watch over your pets when you aren’t around.

Constantly monitoring the temperature of your beloved pet ensures not only its comfort but also its overall health and safety. Using a wifi thermometer, you’ll be able to receive alerts of when the temperature falls or rises above the acceptable range and take the necessary preventive steps

pet monitoring

No more worrying about the pet you left at home while you’re out there traveling!


Up to 99% of folks who own a cabin or simply a vacation home have a wireless sensor installed in them.

This makes sense given that you’re not always around your vacation home and you want to know how temperature and humidity conditions are faring inside there.

The device will help keep watch over various incidents such as furnace failure (temperature drop alerts), frozen/burst pipes (reported as humidity spikes), and so on.

And this enables you to take the right action on time to prevent mold growth as well as costly damages to your investment.

Basements and attics

Sometimes basements and attics act as good store locations for our variables.

If you’re storing something in your basement, attic, or even storage locker that’s of great value and requires constant temperature monitoring, you can also count on a remote temperature sensor to make your job easier.

Not just your variables…constantly monitoring your attic or basement temperatures will also help prevent the growth of molds.

Cigar Humidors

It’s impossible to find a cigar user who doesn’t have a wireless temperature and humidity sensor.

This comes from the fact that cigars need to be checked continuously for temperature and humidity. And that’s because the temperature and humidity at which you store them can significantly affect their freshness.

Since you’ll not always be with your humidor wherever you go, using the digital thermometer will help you keep an eye over your cigars and ensure they don’t get moldy or dry out.


Hydroponics, the method of growing plants without using soils, has become increasingly popular in the US over the last few years.

That being said, it’s worth noting that different plants will thrive under different temperature conditions. Plus, too much or little humidity can significantly affect the pollination of your plants.

It, therefore, makes sense that one of the things you’ll need to ensure successful hydroponics is a digital thermometer & hygrometer to help you keep tabs of your plants and provide them with optimal growing conditions.


If you have a chicken incubator at home, you already know that the chicken requires a certain amount of heat for proper development and hatching.

Since you can’t always stay beside your incubator, it’s important to install a wireless temperature device to track its temperature and humidity. This will help greatly increase the hatching rate.

Wine Cellars

They say the older the wine the better it tastes.

But…have you ever thought about the process that goes in storing the wine to ensure it tastes better?

Well, one of the crucial considerations for proper wine storage is ensuring stable temperature and humidity and conditions.

And what could be a better way of monitoring your wine cellar temperature than a wifi thermometer?

Guitar Cases

If you’ve invested in high-end guitars that cost thousands of bucks, you don’t want to take chances when it comes to taking care of them.

As you’re already aware, most of these instruments are made using different woods which tend to expand and contract differently when there are changes in temperature, risking separation/deformation.

Not just temperature, high humidity levels might make the guitars swell, affecting their tone; low humidity levels can result in shrinking and cracking.

In other words, taking care of your instruments involves tracking the temperature and humidity inside their storage cases.

Production line monitoring

For remote tracking of your production line, a wireless sensor can be your best buddy!

The device will enable you to monitor the production line for temperature, operational efficiency, speed, downtime, and so on from any location and at any time.

Greenhouse management

Remote temperature sensors are also common in greenhouses, where they help monitor temperature and humidity.

remote temperature sensor

This helps ensure that the growing conditions there are acceptable. They’ll send you low and high temperature and humidity alerts to ensure product quality.

Data Centers

Temperature and humidity sensors in data sensors, server rooms, etc., can also play a BIG role in preventing costly damages to the equipment or even fire outbreaks.

Nearly all of these rooms have a cooling system installed to keep the temperatures at acceptable levels.


But what happens if the system stops working?

The devices do the noble task of alerting the manager when the failure happens, enabling them to jump into action and stop a disaster in its tracks.

What’s more, remote temperature sensors with humidity sensing capabilities will also help detect when the humidity gets too high, e.g., in the event of water leaks, as it can lead to damages.
