These are fairly accurate, even in very cold temperatures. The reason for 4 stars is we had one fail (reads 0 for both temperature and humidity) and that I had to get the repeater for two outbuilding since they do not work well behind metal walls.

Este sensor es pequeño, liviano y simple de usar, pero a partir del segundo día comenzó a dar una lectura estática e incorrecta. De acuerdo con la información, el producto puede actuar como un indicador independiente de temperatura y humedad. Al parecer no es así y requiere vincularse con un dispositivo adicional, el cual tiene un precio igual de elevado y quién sabe si con eso realmente funcione.El proceso de devolución y reembolso fue exitoso.

I purchased two of these to try out for a home automation project, and ran them side by side for several months. The price is very attractive, and I also wanted something with a large display. It's hard to get individual parts this cheap let alone a packaged sensor unit.But are they reliable? Shortly after I set them up, one unit would work for a week or so and then "lock up". To reset I had to take batteries out, put them back in, and it would work another week or two. Eventually I contacted support for an RMA return and they asked me to confirm the batteries were quality brand. One unit had Duracells, one unit had a cheap generic store brand (totally unintentional, just what I had handy) but I said it was fine, I confirmed the voltage was perfect. So they authorized me to return it for replacement.But first to humor them I swapped batteries between the units -- and WHOA! Now the other unit had issues and the "broken" unit now worked fine! Now that both units have name-brand batteries I've got no issues - and I'm monitoring them very closely via data logging. I cancelled the return.Tech Info: I am using this with a USB SDR receiver dongle on linux running "rtl_433". It works great, and each device has a 4-digit ID code plus channel A/B/C so theoretically you could run a LOT of these if your software supported it. I think you'd run out of 433MHz bandwidth first. It updates every 16 seconds which is over double the rate of other units I've tried. And it repeats the data 6 times in each transmission to *really* ensure it gets received consistently - which is also more than twice as aggressive as other units. I've really got no complaints at all.Pros:- Low Cost- Large Display- Updates every 16 seconds (verified!)- Accurate: Side-by-side my two units stayed within 0.2 degrees and 1-2% humidity of each other, again better than others I've triedCons:- I mean, it's probably not going to last forever but....?

I am very happy with the AcuRite Temp Humidity Sensor with LCD display.I got this monitor/sensor for my unheated (except by convection up the stairs) upstairs bedroom and an add-on to the sensors connected to my AcuRite hub. This is the model with the LCD display so I can just look at it and know what temp/humidity are in my room. Courtesy of my AcuRite network hub I can check the upstairs temp/humidity on my iPhone along with the outside and other inside sensors that cover my living room, basement and front porch.As a stand-alone unit it's nice and gives results very close to my ThermoPro non-connected temp/humidity display. The LCD display is easy for me to read in most light but a future version might benefit from a backlight button. It really shines for me as part of the AcuRite networked system.The sensor comes with a small paper set of instructions. Batteries not included. I just put in 2 AAA cells and it came on. Within a couple of minutes it was detected by the AcuRite hub and I added it and renamed it to "upstairs". Easy Peasy!This sensor is inexpensive, works well as a in-room display of temp/humidity and is a great add-on to my AcuRite hub/app. Small simple and easy to setup completes the picture of what I see as a 5 star product. I'm very pleased.

You might not expect very much from this little thermometer when you first see it, after all it looks pretty much like most of those little cheap plastic things that are supposed to tell you the temperature in your room. It actually costs less than many of them so you might simply skip right over it without giving it a second thought. But wait, for about twelve bucks this little gadget is worth consideration, if you happen to have the right AcuRite home weather station components or are planning to get one.I have one of their more deluxe weather stations, although it’s not necessary to have one to consider this sensor. My unit has one of those weathervane sensors that mounts on the roof to monitor rain, wind, temperature – actually five different things, which is why it’s called a 5-in-1 weather station. The indoor display shows you all that and keeps a record of the maximum, minimum and trends over time. What’s especially nice about the unit I have that it works with their app so I can check everything I mentioned and more on my phone or tablet device, not only from home but from anywhere in the world. I can even have it email me or text me an alert so it gives me extra security of knowing about temperature extremes that could cause pipes to freeze or even if the room is suddenly getting too hot, like in a fire. I can even add sensors for the freezer, swimming pool, fish tank and all kinds of other things that could be subject to temperature extremes.What this device does is gives me extra temperature and humidity readings for different rooms, like maybe the attic or storage shed. There are two different versions of it, one is just a sensor and the other is this one that adds a digital display. They are both priced the same so my logic is why not get the one that also gives me a remote readout as well as just being a sensor. I don’t know how they can afford to sell this thing with built in wireless connectivity to your weather station and phone app for only twelve bucks.Here’s something they don’t directly say but if you dig deep enough you can find some background information about it. The temperature and humidity sensors built in to AcuRite weather stations don’t last forever, after time they will start giving you strange results and keep telling you that they lost their signal or that the batteries are dead even if they are fresh. There is a replacement module that sells for something like four bucks for the rooftop unit but the one built in to the indoor readout can’t be replaced. Well, that’s not 100% true, what you can do is disable it in software and add one of these little remote sensors to replace it and the app won’t know the difference. So for a few bucks getting this thing essentially bought me a whole new weather stations.

This AcuRite temperature and humidity sensor functions as described and is accurate when compared with a digital thermostat and other thermometer. The two arrows that indicate average changes in humidity and temperatures are actually very useful in determining what schedule to put your digital thermostat or humidifier on to maintain a more consistent room comfort level. The Low, OK, and High humidity level indicators on the house in the middle are useful for adjusting the relative humidity to a comfortable humidity level for the current temperature. Overall, very happy with the performance of this sensor.

In the end this appears to be working properly but took longer than it should have to set up. The instructions for setting up the base station do not mention anywhere that a temperature sensor needs to be on first. We tried calling for help on the # provided (which is not toll free) and was put on hold for about 10 minutes before we were given the option to leave a call back # to hold our place in line. It has been 2 days now and still no call back. Luckily we finally put batteries in the thermometer and the base station finally connected to the app. The app now appears to be reporting everything properly but needs better set up instructions and much better phone support.
