ThermoPro TP55 Digital Indoor Hygrometer Thermometer, 4-Inch Temperature / Humidity Monitor with Touchscreen and Backlit, Indoor Room Thermometer / Humidity Meter for House Home Greenhouse

This unit was smaller than I expected it to be, but actually it’s plenty large enough for its purpose. Digits are easy to read. I installed the sensor outside underneath my deck, on one of the upper boards. Then I put the display unit in my kitchen, only about 12-15 feet away. At first I placed the display unit on my fridge using the magnetic backing, but when I did that the display disappeared. It says somewhere in the manual that putting it on a metal surface with the magnets may cause it to have problems receiving the signal from the sensor. So a no-go on that. I put it on my counter top and it receives just fine. The external sensor I just hung on a nail. VERY easy install!!! Hahahaha I like how this unit gives a readout of temp and humidity for indoors and outdoors, and also a “trend line” for each - is it rising, falling, or remaining fairly steady? That’s nice. Also, the readout on mine seems to be pretty accurate. Be aware that when you first install it, it will take some time (maybe 30 to 60 minutes) for the display to give accurate readings indoors. Takes times for the sensor to adjust, I guess. Ever since that initial period it’s been spot-on. Before looking these up on Amazon, I had no idea that these things even existed!! That is, external sensor sending wireless data to internal display unit. That is so cool!!! And amazingly inexpensive too. I’m so impressed, that after I do a residential move in the next year, I plan to get one of the higher-end weather stations, that does it all - temp, humidity, barometer, wind speed, rainfall amounts, etc. THAT will really be cool!!! But for now, this little device works just find for my needs.

I'm actually going to take a bit of time and write a review, because I really think this product deserves it. I've only had it for around two weeks, but so far, so good. I got this wireless thermometer for a bit of an unconventional purpose; as a wireless way to monitor temperature and humidity (mainly humidity) in my Crested Gecko's vivarium. The setup I have really doesn't allow for devices with cords/probes, and reviews for thermometer/hygrometers that were actually made for pets were pretty dismal. So, after seeing this new ThermoPro product with great reviews, I decided to give it a try (my gecko has a pretty big viv and he loves exploring new things, so the addition of a small sensor wouldn't bother him). The outdoor sensor seems to be working great thus far, no major erratic swings in readings at all (unless I do something to make it change, like misting the viv). It's waterproof, but you do need to have it upright so that water doesn't enter the sensor at the bottom. It has a little hole at the top that I threaded a paper clip and string through so I could hang it on a vine. It also has a bright red light that flashes every 30 seconds or so when it sends data to the main monitor, which I worried might bother my gecko, so I carefully covered the solid plastic and red light with dark painter's tape, leaving all the sensors and compartment-opening-points still exposed, and now the light is not noticeable at all, unless you're really hunting for it at just the right angle. Adding the tape did not affect the temp/humidity readouts at all; they stayed the same after applying the tape as they were before. The main readout monitor itself is really nice. It took me a few tries to really get the hang of the controls, but since there's only 3 buttons to tap, it's not that hard. Touch screen is hyper-sensitive, and the backlight (which I thought I would never use) actually is handy since it's positioned in a room that gets hardly any light after sunset, and the numbers can be hard to see if I want to check them in the evenings. But this room is exceptionally dark; the contrast on the readout is more than enough to be easily read in a normally-lit room. As far as accuracy goes, I have to say that it is accurate simply because it says the same things several of my other gauges do. I have one mercury-style thermometer, one analog thermometer, one thermometer/humidity laser gun, and one analog hygrometer. Between all those devices, the numbers really don't change. If anything, I would say my temp gun is the least accurate, but only because it isn't measuring the temp of the air, but the temp of the material it's pointed at, which varies greatly. Therefore, its accuracy is not quite in the same category. At any rate, I just got up and checked all the gauges, and they're identical to what this ThermoPro wireless device says. I find it hard to believe that so many different devices could all be wrong in the exact same way, so I believe this one is accurate. Setup was fairly quick and simple, and took way less time than the directions indicated; so much so that I set it all up twice just to be sure I did it right the first time. Same results, so it looks like it's all correct. All in all, it's shaping up to be a great little device, and I'm glad I got it. It gives me peace of mind to know that everything's the way it should be in my gecko's home with just a quick glance at the screen (which I placed on a nearby bookshelf), and I love knowing the temperature/humidity of my own home, since I did not have any sort of fancy thermostat before (old baseboard heating). I also like knowing that multiple sensors can be registered, so if I ever want to actually put one outside, I can get one and easily do so. If anything changes, I will update this review, but as of right now, I am very happy with my purchase. :)

It’s small so it can be taken around easily. I like that it has magnets and a stand, so you can use it however you like. It works well, quality is good, doesn’t feel cheap. Love the backlight that’s allows you to see the temperature in dark rooms or at night. I’m still not certain about the accuracy, I got this because I wasn’t sure about the other thermapro thermometers I had, but it doesn’t feel like it’s accurate. I’ll have to do some more checks. Other than that, it does what it’s supposed to do and looks good too. No alerts yet, still using it for now.

من يوم مااشتريتها مااستفدت من القطعه الخارجي غير شغاله وغير فعاله يجب ان تلصق القطعتين بجانب بعضها حتى درجة الحراره الخارجيه يتم قراتئها وهذا الشي غير عملي وغير فعال كيف احصل على درجة حراره داخليه وخارجيه اذا!!! السعر مبالغ فيه

Great quality thanks

Buen producto,

Vivo en costa y con una humedad muy alta. Lo uso para controlar los niveles junto con mis deshumificadores.

Excellent Hygrometer and Thermometer. It seems to provide a very reliable reading. Batteries come included. The temperature readings can be changed between Deg F or Deg C. I like the magnet at the back that makes it installing easier on a mettalic surface e.g. a fridge door.
