ThermoPro Bluetooth Thermometer Hygrometer, 260FT Range Temperature Sensor Greenhouse Thermometer, Remote App Control Temperature and Humidity Monitor with 2-Year Data Logging Export (TP351)

Excellent product. I should’ve read the description better because I thought it had a barometer sensor. I have a ThermoPro indoor/outdoor weather station. The station tracks barometric pressure in addition to temperature and humidity to give an estimate of the forecast. This Bluetooth module works great, but again, it only monitors temperature and humidity, not barometric pressure. If they ever offer one with a Baro sensor I would buy it in a second! The app works great and is easy to setup and easy to read the info. Haven’t had it long enough to determine battery life, but it does include batteries that look to be decently made alkaline. You can’t beat the price for what you get, and the app is free as well. I compared the humidity and temp readings to 3 other units known to be accurate and this module was accurate to within .2 degrees on temp and 1% for humidity. Lastly, the item is small and inoffensive to look at, we have it hanging from an outdoor light.

I LOVE this thing. Simple to use and cheap. The app is easy to install and doesn’t make you sign up for memberships or pay to use it (as of 4/2026). Data tells me exactly what I need to manage my greenhouse temps and humidity. I even have an alert for freeze temps and was able to go out at night and save my starters from damage. Super pleased with the purchase.

I needed a way to monitor my greenhouse temps and humidity as I get ready for the upcoming growing season. I wanted one that was battery powered and could be read from my house (a fair distance from the greenhouse.) This does what I need as long as I'm in certain areas of my house, which is good enough for me. So far the operating temps are as described, as it recorded overnight lows below 0˚ F a few times.

These ThermoPro Bluetooth hygrometer thermometers have been excellent so far! Setup was quick and easy, and the app connected to both sensors without any problems. I use them in different rooms to monitor temperature and humidity, and the readings seem very accurate and update consistently. The Bluetooth range is impressive, and I like being able to check conditions remotely from my phone without walking around the house. The app is simple to use and the data tracking/history feature is really helpful, especially for monitoring indoor comfort, plants, or storage areas. The sensors are compact, lightweight, and easy to place anywhere. Battery life has also been good so far. Overall, this is a great value for a 2-pack and a reliable option for anyone needing accurate temperature and humidity monitoring.

Title: Better Than the Wall Thermostat—Real Data Where It Counts Rating: 5/5 Stars The Verdict: I use the heck out of this ThermoPro TP351. In fact, I use it so much I often forget where I've hung it. Whether it's monitoring the house or deployed for long-term camping trips, this little sensor has become indispensable. Why It Works: Real-World Accuracy: Don't trust your wall thermostat. Those units often read the micro-climate of the wall itself, not the room's actual air. By hanging this in the middle of the room, you get the true ambient temperature and humidity. The difference is night and day. Rugged Simplicity: No screen to crack, no buttons to wear out. It's small, almost too easy to lose, but that's the trade-off for a device that just works via Bluetooth. Phenomenal Range: The 260ft spec is conservative. Outdoors in the clear, I get significantly more range. Indoors, I can step outside and still get a solid reading from inside the house. Data Power: With 2-year data logging and export capabilities, this isn't just a thermometer; it's a trend analyzer. You can spot humidity spikes or temperature drifts long before they become issues. Bottom Line: This is an excellent purchase and a fantastic value for the dollar. If you need accurate, remote environmental monitoring without the hassle of screens or complex setups, the TP351 delivers. It's the kind of gear you rely on when the data needs to be right.

Fantastic little unit! I put this in my Hoop Coop for my hens this winter to monitor temp and moisture content as to avoid frostbite or breathing issues. I’m so happy with this product!! It works superbly!! It has a pretty good reach for the Bluetooth as well. If you are looking for an accurate and dependable tool for monitoring temp and moisture look no further. This even graphs out all the data for you to be able to monitor your daily and weekly temps. It pairs with your phone and is easy to navigate. It has been consistently below zero here and I just now had to change the batteries in it. I would definitely recommend this product.

Amended. I purchased seven total. One stopped working after the fist week. Ironically it wasn’t either of the two outside units. The other was 10* off right out of the box no matter where I put it. All the rest after two weeks have been accurate. That’s two out of seven. At $12.00 each you be the judge. I am very surprised. I purchased three of these and I’m amazed at the accuracy and ease of setup. They all paired easily and accurately. All three synced with one another and the temperature setting on my ac thermostat. I labeled each one; Attic, Living Room and Outside. (I know. They’re designed for indoor use, but I wanted to see for myseif. They’re so inexpensive it won’t break the bank to get a another. Which is exactly what I did.) Then I set the parameters of each one, which was also easy and intuitive. In addition, the range for my intended use is approximately 60 feet max. So far they have all remained paired without any hiccups. I am so impressed I ordered two more immediately. Time will tell but so far, I highly recommend.

Got this a few months ago for my small pop up greenhouse so that I could keep track of data easily thru time and also get notifications if something isn’t working inside of it so I can address it before my plans croak. As far as it’s pure, physical functionality is concerned, it turned on it connected to my phone and it worked, at least at first. I believe I purchased this sometime in October or November and it’s late January right now and it has already stopped working and it’s now passed the timeframe in which I can return the product. I initially thought that maybe it was just out of batteries since it was still running on the first set That it came with, but that was not the case. I changed the batteries, but it still would not turn on after I changed the batteries. I even attempted to disconnect the device from the app and reconnect it, however, after I disconnected the device from the app and searched to try and reconnect it, the device was not showing up on the list to connect it again. Maybe I’ll try some additional troubleshooting, like uninstalling and reinstalling the app, and if I do so, I will update this review accordingly, but thus far I am extremely dissatisfied with this device. Not only has its pure functionality stopped working, it also has been historically, extremely inaccurate, up to being about at least 10° colder than the actual temperature. I have another temperature device in my greenhouse that controls the temperature in which my heater kicks on and turns off, so it has a separate temperature gauge on it for it. This device was always registering as 10° colder than that one, which was a simple metal probe type device and only measured the temperature. The inaccuracy didn’t bother me so so much, because a main function that I wanted was to be able to be notified in the event. Something inside went wrong And things started to freeze up inside of the greenhouse and having a temperature gauge that was registering temperatures 10° lower than the true temperature would only serve to notify me even earlier of any potential issues going on plus, when I would look at the data on the app, I would just keep in mind. It’s inaccuracy and account for the inaccuracy inside of my mind when looking at the data just the same as one would do if you had a clock that was 10 minutes fast or slow. I was still able to get an idea of what the conditions were like inside of the greenhouse without actually having to go inside of it and to me, the issues did not warrant an immediate replacement of this device for a new one that works properly and that is accurate. Because I keep the temperature in the greenhouse Just warm enough to survive and be comfortable for my tropical plants, to try and conserve an energy and keep the temperature on the lower side of the spectrum in which the plants are comfortable with the inaccuracy of the device was kind of a big deal. Even tho I didn’t feel it warranted an immediate replacement, the logic behind it was that “at least I have SOMETHING, and something is better than nothing for now” - as I did not want to spend even more money on getting a new one. Now that the device isn’t even connecting to the app whatsoever, I don’t even have that “something” anymore. And it’s too late to return it now.
