Perfect for my indoor garden
I've been using the Inkbird IBS-TH2 for a few months to monitor my indoor plants, and it works flawlessly. The app alerts me if humidity drops too low, helping me keep my plants healthy. Easy setup and very accurate readings.

★★★★☆
Good value for the price
This sensor provides reliable data and the battery lasts a long time. My only gripe is the Bluetooth range, which means I have to be relatively close to get the updates. Otherwise, a solid device.

★★★★☆
Useful but app could improve
The sensor itself is accurate and compact, fitting nicely inside my wine cellar. The app is functional but sometimes slow to sync, which can be frustrating. Still, it’s a helpful tool overall.

Great sensor, minor flaws
I like the Inkbird IBS-TH2 for tracking humidity in my greenhouse. It’s easy to move around and the alerts are handy. Wish it had a small display so I wouldn’t always need my phone to check readings.
