Antonki 2 Pack Room Thermometer for Home, Hygrometer Indoor Humidity Meter Gauge, Digital Temperature and Humidity Sensor Monitor for House, Terrarium, Incubator, Greenhouse - Battery Included

Over all for a cheap very cheap set of humidity and F temp readers what more could you ask for? I wanted to have an indication of the top third floor or house and second floor of house. We have like 4 different themometers indoors and outdoors for downstairs but we cool by opening windows in our NW MT mountain area. The house develps stratus temperature layers. Cool to cold downstairs like 54 to 70 F and then up a level and we are at mid 70's to higher 80's. Third floor up and it's high 80's into 90's sometimes as high as 96. I had bought good quality thermometers but hubby took them over to put in freezers. Too bad they were more accurate. Anyway after years of complaining on my part I finally ordered these. They took a bit to get together so have patience. I let them be over night and by morning they were close enough. Accurate no they are not lab quality and the cost of lab accuracy would be a heck of a lot more than these little readers. (I do have some really great digital themometers I use in my coolers and freezer when camping. I have a Goal Zero 1400 that keeps a 27 quart freezer working 24/7 as long as I have sunshine and solar power to keep battery charged but also then exchange 1 to 2 half gallon frozen ice bottles on a daily basis for cooler. This can raise the temp in the freezer for a bit and it's nice to konw what the cooler is doing too. So bought those with water proof probes and where you can see ambient outside temps and use of probe the inside temps in the freezer and the cooler. So yes I could use those about home and have but wanted something just for that. Only thing I would do better is make sure there is a small place on back side to add adhesive strip or adhesive strip velcro tab to place on a wall without interference of the sensors or the battery box. They didn't. If you have a shelf or can figure out a means to hang upside down and then right them up to read via their small stand then you might be able to hang them too. Anyway haven't worked that out quite yet. Will put one in the hall of each floor going up the stair wells to get a feel for the clime so to speak as I climb. Very close to what I would expect and good enough for my personal feedback in general. (Should I turn off computer because it's too hot in home office for example.)

I purchased these because I needed to replace one that had knocked into a glas.of water. The 2 pack was only $1 more than the price I paid for the one I replaced. I like the fact that you can choose from different colors, and like the peach tone I chose. The display is large and easy to read. The temperature reading seems fairly accurate (compared to the temperature on my thermostat, it is about 1 degree lower). As an added bonus, these have magnets on the back which are a useful option depending on where you want to place it.

I placed them on my fridge with 4 - 6" between them. I swapped positions and distance between them and locations on my fridge. I used the fridge as it's open to the main living area and a nice metal surface. Positioning had no noticeable effect on the results. Over a 10 minute period of time they would only have the same temp every little bit. There was almost always a small difference, sometimes as much as 2° difference. I'd like to see them be more accurate but I guess at this price point that isn't to bad. humidity was not a concern for me but never synced and was about 1 point different.

Simple, small, and easy to read. They are about 2" x 2" and i purchased the loght gray as they will blend the best. I bought these because my house can be very dry in the winter AND my bedroom always runs hotter/colder than the rest of the house. I have a newborn so I wanted to be sure things are comfortable for her in the bedroom at night and these work out great! They will also be great for monitoring humidity for my plants. My only complaint is that they are magnetic, not wall mount, but that's fixable with some command strips. I likely assumed they were wall mount, but I'll have to double check the product description. Tip: wait about 10 minutes after turning on for them to read the same if your testing, otherwise you'll think they aren't accurate.

We've had a long drought, and with it now cold and the furnace running so much, my sinuses were crispy! With this tool I can be sure how to adjust the humidifier to stay healthier! Very Good Price! Accuracy is obvious! Even cute sitting on the table. I got a two-pack of green ones. The one I put in the bedroom soon dropped like a rock, and NOW I know I need a second humidifier going in there too! Wasn't just my imagination. Lol.Edited to say: With all the BAD reviews, I can only guess there is a Quality Control problem at the factory, or severe problems in the shipping! I must have gotten LUCKY!😁I added the pic because someone asked the actual SIZE of the digital numbers and letters. 3/4 inch

It took a few hours for the temperatures to get adjusted accurately (at first I thought I had 1 good & 1 bad thermostat). After waiting a few hours & checking back in on the thermostats & humidity they both agreed with eachother & seem to be accurate within <1/2 of a degree. Both have been at the same humidity accurately from within a few minutes upon turning on. For the price & getting 2 of them, it’s nothing but a positive review for now. I’ve only had them for 2 days so far so I can’t speak long term. But as of right now I can’t say anything other then 5 stars.

As I write this, I watch the screen jump from 75.2 -> 75.0 -> 75.1 -> 74.9 and all points in between over the course of 2-3 minutes. Maybe this detects each tiny temp fluctuation in every passing air current, or maybe the sensor is just "so-so." The humidity monitor takes some time to equilibrate, but appears similarly accurate. This is useful for "close-enough" monitoring, but don't count on it to be precise. Hey, the package clearly states it has a +/-2 degree F and +/-5% RH variability, so caveat emptor, right? Bought it at a discount so I will count this a good value for everyday measurement.
