Wi-Fi Thermometer – The Ultimate Buying Guide

What is A Wi-Fi Thermometer?

A remote temperature monitor is a small wireless sensor that uses a cell phone to track temperature and humidity levels. The best wireless temperature sensors come with a mobile app that displays real-time data and lets you create triggers to notify you of any significant environmental changes.

To accomplish remote capabilities, the devices can connect to a Wi-Fi network, Bluetooth, or cellular network. This allows you to monitor the conditions from anywhere at any time and receive warnings on your smartphone, computer, or tablet.


Why Wi-Fi Thermometer?

Temperature and humidity can have a negative impact on your health. In fact, most people living with asthma have issues with wetness. Most homes are actually too humid for health reasons, which can encourage the growth of fungi, mites, and other pests. Dry air, on the other hand, can be just as terrible.

When the skin, mucous membranes, and eyes become dry, viruses can spread more easily. And that’s just considering people. What about furniture made of wood? Instruments? Incubators? Art? Temperature and humidity can damage or destroy your belongings if they are not monitored.

Hence, maintaining a constant temperature and humidity level is often necessary to avoid costly and irreversible damage to property and valuables. An urgent signal from a remote temperature sensor will allow you to take action before the temperature or humidity reaches dangerous levels.

Traditionally, remote temperature monitors have been big, expensive systems with high monthly subscription rates. Companies rapidly realized how crucial monitors are to many business owners; therefore, they became exorbitantly expensive and out of reach for most individuals.

As a result, acquiring something like Wi-Fi thermometers can help you tackle these problems.


Factors That Make A Good Wi-Fi Thermometer

Range of Temperatures

Whether you’re buying a regular thermometer or a Wi-Fi thermometer, make sure to check the temperature range to make sure it can show you readings in the range you want.

As a result, temperature ranges such as -4 degrees Fahrenheit to 140 degrees Fahrenheit or 32 degrees Fahrenheit to 482 degrees Fahrenheit exist, with the greater range always being preferable.


Sensor Reliability

Accuracy is crucial when using any form of measurement tool. However, the level of precision you require depends entirely on you and your application. When you’re taking a measurement to see if you should wear a jacket, the accuracy of your measurement isn’t as important.

When you’re doing something more precise, precision becomes more important.


Compatibility with Wi-Fi

If you’re familiar with Wi-Fi networks, you’re probably aware that the most common frequencies are 2.4 GHz and 5 GHz. While most Wi-Fi thermometers only function with 2.4 GHz Wi-Fi networks, some work with 5 GHz Wi-Fi networks as well, making them more versatile.


Size & Portability

The thermometer can be used in conjunction with a display unit to show temperature data. However, these instruments are increasingly being built without any sort of display. Instead, they make it possible for users to acquire data solely through the Internet.

The amount of interaction you plan on doing with the bundled control app will determine whether or not you require a display. A display might be handy for users who want to interact less with the app or conduct more hands-on management.

You don’t have to be concerned with the size of a display device. However, the size of a sensor is vital to consider, especially if the sensor will be placed in a tiny location. Most sensors will have a diameter of only a few inches, which is usually not much larger than the batteries they contain.


Power Source

The majority of these digital instruments will be powered by standard AA or AAA batteries.

It’s even better if they’re rechargeable. You should search for a unit that can last for around a year before you need to replace the batteries. Because most well-designed sensors only report once every minute, this is the case.

Reporting more frequently consumes more battery life and isn’t necessary for most people in most situations. In fact, in most cases, even a one-minute reporting is too quick. Going above and beyond that will simply add to the cost and hassle.

For wireless monitoring, the Govee wireless temperature and humidity sensor are connected to the Govee Smart Home iPhone and Android app through Bluetooth or Wi-Fi (2.4 GHz only). The app is free to use and does not require a subscription. The Govee is incredibly economical because you only have to pay for the device’s initial purchase. However, because of the low cost, there are some functional limitations.

You can set temperature and humidity alarms in the app, and you’ll get notifications via push notifications. Unfortunately, there are no alternatives for sending a text message or making a phone call. The device also has a low battery alert; however, it will not notify you if the Wi-Fi connection is lost. By installing the app and logging into the same account, other users can receive alerts as well. Data is uploaded to the app every 10 minutes, and you can access up to 2-years of the data online.

The digital display on the Wi-Fi temperature monitor is a handy feature that allows you to get readings without logging in to the app. The wireless remote temperature sensor comes with a desk stand and may be simply installed on a wall using double-sided tape due to its small size.

The battery life of the Govee is stated to be three months, which is rather short when compared to other models. This wireless thermometer is inappropriate for monitoring cold storage, especially in commercial freezers, due to its narrow temperature reading range. The Govee is better suited to domestic uses such as a guitar box, wine cellar, or cigar humidor.
