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.

thermometers worked well when the app is open and we’re reading the temp remotely,. However the claim that the app will alert when temp or humidity exceed the parameters is totally false. If the app is open the alarm beeps once, that’s it. If you don’t happen to be looking at the app on your phone when parameters are breached, you’re out of luck. The ThermoPro tech support person was very understanding of the dilemma but just told us the alarm feature doesn’t work.

This Bluetooth temperature/hyrometer set up in less than a minute, maybe two minutes if you count the time it took to download the app. Batteries are included, and the app is free, with no registration required. Adding the device is as simple as pressing the + sign and selecting the ThermoPro model in the app.. I’m using this for an unorthodox purpose and something not covered by the stated usages: I hung this outside on a protected fig (wrapped in a tarp) to see whether the pipe warming cable (also unorthodox) was keeping the area above the critical 20 degrees. Even though this doesn’t state it can be used outdoor, the lowest temperature is listed as -4 F, a temperature that we rarely get in my area of PA. Probably because I’m using this outside and through an exterior wall, the range is not great. I have to be about 12 feet away inside. If I were to use this indoors, as intended, I’m certain the range would be better. Still, this is not a WiFi device. You must be within range to get a reading. The price is right, especially for peace of mind. The gauge seems accurate.
