InkbirdMini Digital Thermometer and Hygrometer, Temperature Humidity Bluetooth Smart Sensor, for Guitar Humidor Mason Jar Incubators

Accurate and easy to use... The app is simple to use so far with one sensor to keep track of.. Data and graphs show changes, in temp and humidity, alarms can be set, data can be exported etc... After 3 weeks and over 30,000 samples taken the battery still shows a full charge and everything has worked as expected... Lots of stuff to play around with.... Perfect for my jars but can be used in my room too...

Works well. You can turn the blue tooth off to save battery

First one I bought lasted a few days now I got a 2nd one and it only lasted a month and I thought the battery was dead. I didn’t have to worry about humidity in my guitar case for a while so I waited til winter to start monitoring humidity. Well I go to replace the battery and it doesn’t work. Don’t waste your time with these cheap monitors. I know others had success with these (reason why I bought it) but I’m not willing to buy a 3rd time

When I bought this it was $17.99. Now that I have it the price has gone up and in my opinion even at $17.99 it was overpriced. The app is a very basic app. You can set notifications to alert you if the temperature or the humidity levels you set go above or below your settings. But… the notification only alerts you when you open the app to view it. Not when your phone is closed or the app is not open. Also the alert is a cheap car horn sound. Last is the import one the Bluetooth range to your phone to the temp device is very limited. I have to be in the same room so I can get a reading. So I will say you range out after 9 feet.I am currently using this for my cigar humidor. Until I find a device just has small with a digital readout the has a better range this is it. But not for $20 + .

Inkbird always pushes out quality products. The ability of this sensor is great - curing product I can check without disturbing the jar and exposing to unnecessary UV or light in general that would degrade my product. Couldn't have asked for more

The media could not be loaded. Perfect little thermometer/humidity gauge, it displays in F* and C* and easily connects to my smartphone via Bluetooth. I even comes with little Velcro taps so you can mount it anywhere. I love the fact that I can check on my grow tent by just tapping on an app! Inkbird is quickly becoming one of my favorite brands!

Inaccurate and eats batteries to the tune of one per month almost.

This little gadget is very useful if you have a humidor box: it is a quality sensor to mesure tempriture and humidity also when you can’t see the box. It is because the bluetooth, so you can just use your phone to check out ehat is the current humidity inside your box
