For More: WiFi Temperature Sensor Buyers Guide and Test Results
Not everyone needs a full-fledged weather station. In some cases, wireless temperature sensing is all you’ll need. That’s the purpose of this guide. We’ve reviewed several WiFi temperature sensors over the years, some with as much functionality and connectivity as their weather station brethren.
You can place a WiFi temperature sensor just about anywhere. For example, our Temp Stick (in the picture above) resides in the pantry in our basement — an area of our home where humidity often gives us trouble. But you could place one in your greenhouse to make sure your plants are in an optimal growing environment or in remote areas of your home to ensure your HVAC system is cooling (or heating) your home efficiently. Maybe you want to prevent frozen pipes when low temperatures are expected during the winter.
We use our Temp Stick WiFi temperature sensor for just that purpose and to make sure our damp basement stays dry. Wireless thermometers can be pretty straightforward, measuring just temperature, or more fully-featured, like the Temp Stick or SensorPush HTP.xw. These wireless temperature sensing devices measure temperature, humidity, and even atmospheric pressure, along with tools to review collected data.

- The best remote temperature sensor on the market
- American made
- Highly accurate
- No subscription fees
- Higher price than other options
We are huge fans of the Temp Stick WiFi Temperature & Humidity Sensor. Made in the USA by Ideal Sciences, it’s the most fully-featured remote WiFi temperature sensor we’ve reviewed. Its factory-calibrated accuracy is top-notch, and it can continuously measure air temperature and humidity levels in your home in as little as five-minute intervals. You can remotely monitor sensor readings and recorded data on its web-based dashboard (a mobile app is also available).
Even though it is powered by 2 ‘AA’ batteries (Lithium batteries are recommended), as long as you keep the default update interval settings, you should get at least a year of use without needing to change them. A low battery alarm will let you know when to change the batteries.
We use our Temp Stick to remotely monitor temperatures in the basement of our 1920s home, which is prone to humidity problems. We use the alert function to let us know when to run the dehumidifier. The only thing we’d like Ideal Sciences to add is IFTTT compatibility to connect to other smart devices in the home. This WiFi temperature sensor would blow any of our other recommendations out of the water.
- Bluetooth compatible (Wi-Fi Gateway sold separately), 325-foot range
- The sensor can store approximately one month of readings
The Temp Stick is a big sensor, so you might have trouble fitting it into tight spaces. For these types of applications, we’d recommend the SensorPush HT1. Measuring a little over 1.5 inches square and less than three-quarters of an inch thick, you can fit this just about anywhere, and it lasts an entire year on a single charge.
SensorPush also offers two higher-end options: the HT.w, which increases battery life to two years and is water resistant, and the HT.xw, which adds barometric pressure and higher quality instrumentation.
One big drawback to the SensorPush wireless thermometer hygrometer is its data storage capabilities and lack of WiFi connectivity. Unless you purchase the WiFi gateway, you’re limited to connecting to the device via Bluetooth and can’t remotely monitor the sensor. But if these aren’t a concern, you can save quite a bit of money over the Temp Stick by going with the SensorPush instead, whose temperature accuracy rivals the Temp Stick thanks to a Swiss-made sensing component.
This package includes three temperature sensors and a Wi-Fi gateway to allow you to access the sensors. But it does not have the true remote monitoring of the Temp Stick.
At first glance, the Govee WiFi Hygrometer Thermometer 3-Pack looks like a great deal and is similar to the Temp Stick WiFi temperature sensor. However, there are some critical differences between the Temp Stick or the SensorPush and Govee’s version. While it is Wi-Fi-capable, it only allows you to view data from your sensors while on the same network as the WiFi gateway included in the package.
Like most other WiFi temperature sensors, you cannot view your data over the internet through the app. And the battery life at only four months is pretty short among the devices we reviewed for our Best WiFi Temperature Sensor of 2022 rankings. However, you can go wrong at this price. And the WiFi gateway can support more than the three sensors it ships with, up to 10 sensors in all, two more than the Ambient Weather WS-10.
While this model does have Wi-Fi and Bluetooth, it only allows you to view data when you're on the same network as the device.
The Govee WiFi Thermo-Hygrometer doesn’t require an additional hub, unlike the previous Govee model. But it still suffers from the same lack of remote access as other Govee WiFi temperature sensors. That said, issues like battery life are addressed, and an included lanyard allows you to hang it in the location you want to monitor.
While it might suffer from a few functionality issues, the Govee WiFi Thermo-Hygrometer is our list’s cheapest wireless temperature sensing device. It overall performs well enough that the lack of remote access isn’t that much of an issue.
The HTP.xw adds barometric pressure readings and like the HTP.w is water resistant.
- Bluetooth compatible (Wi-Fi Gateway sold separately), 325-foot range
- The sensor can store approximately one month of readings
The SensorPush HTP.xw is the company’s top-end model and measures temperature, humidity, and pressure (one of the few WiFi temperature sensors we know that can do that). With higher quality instrumentation, readings should be more accurate — however, you’ll still need the WiFi gateway to connect your sensor to the internet for remote access.
That puts it in the neighborhood price-wise of the Temp Stick, which we feel is an overall better buy.
With the same feature set as the HT1 (temperature and humidity), the benefit of the HT.w is water resistance.
- Bluetooth compatible (Wi-Fi Gateway sold separately), 325-foot range
- The sensor can store approximately one month of readings
The SensorPush HT.w is essentially the same device as the HT1 but water-resistant. It also has better battery life than the HT1, but we’d consider other options unless you really need water resistance. However, the device itself is quality, and why we considered it for our Best WiFi Temperature Sensor of 2022 rankings.
The MarCELL combines a remote temperature sensor with cellular data service through Verizon, with plans starting at $8.25 per month.
There are situations where a standard WiFi temperature sensor isn’t going to cut it. For these situations, the MarCELL cellular monitoring system is a perfect solution. While it requires a subscription plan ($8.25/month) for its internet connection, the device has an integrated Verizon cellular modem, allowing you to place the device anywhere there’s a Verizon cellular network signal.
This makes it an excellent solution for an RV, vacation home, or any other remote location where you might not have WiFi network access, a mobile hotspot, or the ability to visit regularly to connect to the sensor.
Remember that you must plug the device into an AC unit to operate (although a backup battery can provide up to 48 hours of power during power outages). While we haven’t had a chance to test out the unit yet, verified reviews are overwhelmingly positive, even with the additional subscription costs necessary to use the device.
Also Consider
The below options do not include WiFi connectivity, so they didn’t qualify for our rankings for the best WiFi thermometers but are still decent remote temperature sensors in their own right. They require a console to view the readings.
- Includes an indoor thermo-hygrometer and three remote thermometer/hygrometer sensors
- Display console shows indoor temperature and up to three outdoor sensors at the same time
- Audible and visual alerts when preset levels are reached
If you’re looking to track temperature and humidity in multiple locations without breaking the bank, Ambient Weather’s WS-10 is an excellent buy. With a large display and accurate sensors, you can monitor the current temperature and relative humidity in up to eight locations (one sensor is inside the console, and you can add up to seven more wireless sensors). The WS-10 is also compatible with the F007TP probe sensor, giving you the option to monitor your pool’s temperature.
You can set alerts on the console to be notified when conditions exceed certain levels, and the battery life of the individual sensors will provide months of use without the need for new batteries. While the display can only display data from four sensors simultaneously, you can use the buttons on the console to scroll through data from additional sensors.
Keep in mind that this model doesn’t have remote temperature monitoring capabilities, as there is no built-in wireless connectivity. Still, the capability for multiple sensors is a huge plus.
- Monitor up to three locations
- Console can display all three sensors at the same time
- Temperature/Humdity trend arrows
- 200 foot transmission range
If budget is a big concern for you, look no further than the ThermoPro TP60S. It is the cheapest recommendation on our list and has over 10,000 reviews, two-thirds five stars. While this package includes just a single sensor, you can add up to two more sensors for three. The console is small and compact. However, it features a large LCD readout, making it easy to view from a distance.
Accuracy suffers a bit, and it’s nowhere near as accurate as our other recommendations (accuracy issues were the most common poor review for the ThermoPro TP60S). But if you are looking for a low-cost alternative, this is the most popular and best-reviewed budget WiFi temperature sensor. However, like anything cheap, you do get what you pay for.

Unlike many sites, we test the products we recommend or have direct experience with the company. We test select WiFi temperature sensors for several weeks, giving us critical insight into long-term reliability, something a quick review cannot. You can see our testing protocol here and our rating formula here.
We’ve also developed a 100-point rating system that judges each WiFi temperature sensor tested on the same metrics. We judge accuracy (or performance), affordability, durability, feature set, and ease of use. These categories are weighted to emphasize accuracy and affordability, making up half of a WiFi thermometer’s score.
However, a candidate for the Best WiFi Temperature Sensor of 2022 can’t only be a great value: it must have accurate measurements, be user-friendly, and have excellent build quality. Our review staff has years of experience using home weather stations and instruments: some of us are degreed meteorologists and scientists. Our writers independently research each device: we do not recommend a device simply because a manufacturer sends it to us.
Frequently Asked Questions
Below we’ve listed some frequently asked questions we hear from readers on WiFi temperature sensors.
What is a WiFi temperature sensor?
A WiFi temperature sensor — also called a remote temperature monitor, WiFi thermometer, or wireless temperature sensor — is a device that measures the temperature and often humidity in an area without you needing to be there. Remote temperature monitors are generally used to check on your home or business while away, but they also have many other uses. For example, you can use them to verify whether food has been appropriately refrigerated or diagnose problems with HVAC systems before they become serious.
Most models “wake up,” take a reading on the built-in temperature sensor, then either use a WiFi connection or an internal cellular device to broadcast the measurement to a central server. After this, the device powers down, improving battery life. On some models, you can get upwards of a year of battery life as long as you use lithium batteries, which most manufacturers recommend.
Image Credit: SensorPushMost remote temperature monitoring systems have a wide temperature range, making them perfect for various applications and environments. Temperature accuracy is as good as most weather stations but without the bulk. You could measure temperature in many places you couldn’t place a weather station.
What are some uses for a WiFi temperature sensor?
– To monitor your home while you’re away
– Temperature monitoring for food storage
– Monitoring HVAC systems
– Greenhouses to know when to open and close vents
And these are only a few of the many possible uses of these devices.
Should I buy a weather station or WiFi temperature sensor?
A wireless temperature sensor is perfect for situations where a weather station’s additional functionality might not be helpful. We see wireless temperature sensors as the best choice for anywhere where monitoring exact temperature changes and humidity levels is important. However, if wind speed or rainfall is equally as important, a weather station is a much better buy.
Can my weather station monitor temperature remotely?
In many cases, yes. For example, Ambient Weather and AcuRite offer standalone wireless temperature and humidity sensors that you can add to your setup. If you have a weather station already, it is cheaper to go this route.
Are WiFi temperature sensors accurate?
A high-quality WiFi temperature sensor is accurate, and most measure temperature and humidity as accurately as the sensors in weather stations. The recommendations in our guide all meet our standards for accuracy and quality.
Do WiFi temperature sensors run on battery power?
Yes! We recommend using lithium batteries, as battery life is far better. Models like the Temp Stick are battery-powered and can run on regular alkaline batteries for up to a year, so you won’t have to worry about a power outage stopping your data logging. Some even have an internal battery that can power the device for months without a recharge. If you select a more frequent update interval than the default, you might need to change the batteries/recharge the device via USB cable more frequently.
Wrapping Up
Remote temperature monitoring is perfect for many situations where a weather station might be more than you need and save you some money. However, don’t just factor price into your buying decisions. Accuracy and expandability are far more critical factors. In the long run, you’ll be much happier with your purchase if you opt instead to use these as your primary factors in what WiFi temperature sensor you choose.
