ThermoPro TP157 Hygrometer Indoor Thermometer for Home, Room Thermometer Humidity Meter with Accurate Temperature Humidity Sensor for Greenhouse Baby Room Office-1 Pack

I used these as a 'scientific yet non-scientific' experiment to see the temp and humidity of an enclosure. They worked great and consistently. The battery worked for about 30 days before needing replacement. The Bluetooth worked through a cast iron enclosure. Super simple. Their app is needed to download and is super intuitive - very easy to set up and use. There is no export to an email I could find so I captured app information my phone screen with a photo. It also tracks the historical temp and humidity. I can't recall how long it showed the historical information on the app. It does not save it either past the advancing date precursor. I used 3 sensors. One was placed outside near my enclosures to track the outdoor ambient temp and the other 2 inside separate cast iron enclosures. For our experiment, the humidity was the surprise bonus metric to capture!This would work great for a house crawl space! It would be readable from outside the house or from the first floor.

If you are looking for a humidity/temperature sensor or low-temp alarm device accessible from your phone, this is it.It is very accurate, has per 24/week/year records, and can alert you at a certain temperature. Very nice. The device is very small, as well, and comes with an optional metal magnetic backing so you can stick it on the fridge, wall, cooler, you name it. Very convenient.It connected flawlessly to the app at first setup, and only took about 2 minutes to do both. At this price point, the quality of this sensor cannot be beat. I am looking to get one for every single room in the house, as well as both sides of the basement. It is just too cheap and too high-quality to not just get more. If you are looking for something like this to help keep humidity levels higher in the winter and lower in the summer to adjust your run times on your humidifiers and dehumidifiers, this sensor is it.Will be buying more.

Works great!I use it in my 3D printer filament box, and it’s very accurate!

In my case this works as advertised. Note that since it’s a Bluetooth device it won’t connect to your Google Assistant or Alexa. It would be nice if ThermPro created a widget so you could check the status without having to find and open the app for an update.

Easy to use ! Worked well!! Great quality ! Shipped fast ! Very clean ! Easy to assemble , very durable , nice appearance , great value for money spent

Works great! Easy to connect to Bluetooth and has a long range. I have it in my greenhouse that is quite a ways from my house and it connects to my phone in my house. I previously bought some other junk govee thermometer that didn’t connect at all, so I was very impressed with this one.

I needed a simple hygrometer to monitor the humidity in a large storage closet where I have my genealogy archive. The ThermoPro TP357 gives me accurate readings with the convenience of being able to check the conditions on my phone using the Bluetooth app. I like that you can set alerts for high and low humidity and receive alerts when they exceed the levels. The Bluetooth is strong enough that it can be read throughout the house. Finally, it uses a single AAA battery instead of a CR2832 disc battery, which is cheaper and more convenient to buy.

Works fine but it is tiny! The dimensions are not easily found in the description and the pictures are deceptive. It is overpriced.
