Review on 🌡️ Indoor Hygrometer Thermometer, Digital Humidity Meter with Backlight, Temperature and Humidity Monitor for Home, Bedrooms, Reptiles, Plants, Greenhouses, and Wine Cellars - Highly Sensitive Humidity Sensor by Chris Hodges

I like this small inexpensive device. I put it on a windowsill first to see how it would do on a cold window for a few days. I then put it in my fridge to see if that changes. That works great! I plan to buy more. It's magnetic, so ideal for the fridge. It has 2 other installation methods. Fridge or freezer where I can see if it's outside of the recommended temperature range at all. It is very easy to use, just insert the battery and go!
