WHO IT'S BEST FOR

Best For:

For the wine collector, greenhouse owner, or instrument keeper who needs the most precise readings: Swiss-made Sensirion sensors deliver ±0.5°F accuracy, the tightest in the Bluetooth lineup. Conditions are measured exactly, not approximately, so you can trust what you're seeing.

For the detail-oriented homeowner who tracks long-term trends in sensitive spaces: The app stores 2 years of data with dynamic graphs. Watch how humidity in a wine cellar or nursery shifts across seasons and respond before conditions cause damage. 

For anyone who wants Bluetooth humidity monitoring with a large backlit display: The 3.5" backlit LCD shows readings clearly in any light. Custom alerts notify your phone the moment temp or humidity moves outside your set range. No registration, no Wi-Fi needed.

Not Ideal For:

Those who prefer a simple standalone display without needing a phone: The TP359 is app-based. For checking readings at a glance without touching a phone, the TP60B or TP65B show all data directly on the device display.

FEATURES

Precision You Can Trust: Powered by a Swiss-made Sensirion sensor, this digital thermometer and hygrometer is accurate to ±0.5°F and ±2% RH, capturing even the smallest changes. Say goodbye to fluctuating comfort levels or damage to sensitive items like wine, instruments, or plants.

260-ft Bluetooth Range for Convenience: Monitor temperature and humidity from anywhere in your home or greenhouse using this unit’s advanced 5.0 Bluetooth chip. No more running back and forth to check conditions—get updates right from your phone.

Understand Your Environment: The app’s dynamic graphs and 1-year data storage help you analyze trends, whether you’re managing a nursery, greenhouse, or wine cellar. Stop guessing and start taking control with actionable insights.

Instant Alerts for Peace of Mind: Set your preferred temperature and humidity levels, and get notified when the environment changes. TempAir ELITE TP359 is perfect for protecting delicate plants, preventing mold in bathrooms, or ensuring comfort for babies and pets.

Clear and Comfortable Display: The 3.5” backlit LCD provides quick, easy-to-read updates with a soft yellow light that’s gentle on the eyes. No more squinting or straining in low light!

Wow what a great tool. It's extremely accurate (tested against smart thermostat) I saw just a -1% deference in humidity. It took about 12hrs to adjust once batteries are installed. Highly recommend this product to anyone who needs to monitor temp/humidity in a specific area.

Using this to track room temperature in a room without a thermostat, this was great in getting an accurate room temperature reading, with the backlight being great for checking temperature in the dark during nightly lows. The app is great for tracking trends over time and logging them, with easy Bluetooth functionality. This is a simple, low-cost solution for tracking temperature trends in any location you see fit!

This is an amazing little gadget if you need to monitor temperature or humidity in a remote spot. I put this in my attic and it works perfectly with the iPhone app. The graphic display over a variety of time periods is very well done.

Very consistent reading and works very well. The batteries they send with it crapped out after a month of just sitting there with out being touched. Had another analog one that read horribly and it was so dry, but yet it read high moisture. This one is well worth the money and has been very accurate no matter where I move it to. Good product I highly recommend it!

It only works when you're at home but it works really well. No more unzipping the tent to check the temperature. Gives The temperature to the 10th of a degree, the humidity by the percentage.But no decimal.

UPDATE: The thermometer was not dead, it just needed new batteries. Still five stars.ORIGINAL REVIEW: I bought this to keep track of the temperature in my office. The building has terribly erratic climate control, so my motivation was to be able to have evidence of the temperature when complaining to Facilities. It has worked well for that purpose. I was looking for some kind of wireless thermometer with a nice display, and this was much cheaper than options by companies such as Govee. ( had two of their thermometers a couple years ago, and they both died a few months after I bought them--so I have chosen to avoid their products from now on.Back to the ThermoPro. The display is clear--a little busy, but easy to read the numbers. You get not only temperature, but relative humidity, as well as the maximum and minimum temperature within the past 24 hours. (Even more evidence to support my complaints.) I highly recommend downloading the ThermoPro app--I use it on Android--to set up alerts, and to get a reading of the data it collects on your phone. It stores something like 2 years worth of data, so you get a lot of detail. Amazon just asked me to review this and I was about to take a picture of it for the review. It has a button to light up the display, and as soon as I pushed it, the display went blank and I can't get it to turn back on. I suspect that the batteries were getting low, since they're the originals (2 AAA's) and I've been using it for several months, and trying to energize the light killed them. I don't have fresh batteries on hand, so I can't test my theory. If it turns out this thing is dead, I'll update the review. However, I have a few other ThermoPro thermometers, one of which died unexpectedly. I contacted the company support and they immediately agreed to send me a replacement, which arrived only a couple of days later. My experience shows that you can trust this company to make it right if you get a defective product, even when you're well past the return period.

The house I live in has two problems with humidity. In the summer the humidity inside the house can get up over 85% (there are unground springs right next to the house). In the winter the humidity inside the house can drop under 10%. So I've bought a lot of humidity sensors over the last 8 years, and put them in different rooms around the house. The shortcoming off all the sensors I have bought is that I have to walk around and look at each sensor to read it.So for me, sensors which will send the data to my cellphone is a najor improvement. My cellphone can store that data and show graphs of both temperature and humidity. You can pick from a graph for the last 24 hours, a graph for the last 7 days, or a graph for the past year. I have four different sensors, and all four show up in the app. And the sensors talk directly to your cellphone via bluetooth — there is no shipping the data off to some company's web site and then needing to register with that web site.I expect this is ThermoPro's first attempt at an app for a cellphone, and there are plenty of improvements that could be made to it. And right now it has a bug where *sometimes* the app will crash when you have the app download all the latest data from a sensor. It does download the data and save it correctly, and then maybe 30-40% of the time the app will crash. I have been sending debugging-info to the company, and they say they're looking into the problem. But even after that irritating bug is fixed, I have other ideas for improvements the app.Initially I bought three of these and have been happy with them (except for the app crashing). It then occurred to me that this sensor could also be very useful for another problem at my house. My refrigerator will be working perfectly fine for 8-12 months, and then over the course of maybe two weeks the average temp will go from 40F to 60F, usually without me noticing it. The problem is just that it needs to be defrosted (even though you won't see ice anywhere in it). I have put other sensors in the fridge so I can monitor the temperature, but of course I have to *open* the refrigerator to check those. I also have to remember to keep checking, and after six months of it working perfectly fine I'll get pretty lax about checking. The sensor ends up buried behind food, etc. And before I know it, I'm drinking milk which is nearly room-temperature.So I put one of these sensors in the refrigerator, and I'm very happy to see that the bluetooth signal still makes it to my cellphone, without me needing to open the refrigerator. So I've bought another sensor to do full-time duty at monitoring the inside of the refrigerator. And I expect to buy a few more sensors in the next few months, for other full-time duties. I think the company says you can have up to 10 of them.As to the accuracy of these: As I said earlier I've been buying a variety of inexpensive sensors over the past 8 years. And to be quite honest, I don't trust any of them to be 100% accurate when it comes to humidity. But I still own all those sensors, and these new ThermoPro TP59 Wireless sensors seem to be about as accurate as the other sensors I own from other companies. At least they have been so far. I still doubt they're 100% accurate, but I'll be happy enough as long as they're consistent. By that I mean that if they say the humidity is 34%, then I want to be confident that the humidity is lower than at times when the sensors say the humidity is 40%. Maybe the humidity is really 30% instead of 34%, but at least I can depend that the humidity really is going lower if this sensor claims that it's going lower. I have owned my sensors for just a few weeks now, so I can't really say how reliable they will be over the full range of humidity that happens around my house!
