Review on 🌡️ Pack of 2 ORIA Digital Hygrometer Thermometer – Accurate Indoor Temperature and Humidity Monitor for House, Office, and Greenhouse by Darren Anderson

not bad; a bit small, no backlight and uses non-standard batteries. I have a small 3D printing room in our basement and temperature and humidity monitoring is important to ensure consistent output quality from my 5 printers. I currently have 6 different used temperature/humidity sensors of different sizes, functions and manufacturers. The devices tested here are the smallest and cheapest in my group. In the group photo, these items are in front. First, they are small. If you're expecting to be able to read their displays from across the room, you'll be disappointed. No problem up close. I have all of these in my 3D printer cases and use them for random temperature and humidity checks. Like others, these items have the ability to report current temperature and relative humidity. However, unlike the others, they do NOT record the 24-hour high/low for these two measurements. This is unfortunate and will eventually force me to replace them as I run my printers overnight and need to know if an unexpected low or high occurs while I'm away. Another missing feature is the missing backlight. To be honest I don't use backlighting as as mentioned all my cases are backlit with LED strips (see photo), but if that's important to you then we guess. The battery used is a 2032 disc, which does not have a long lifespan and is not very common in many families. These units also report a slightly different value than my others. It doesn't really matter, because laboratory-level accuracy is not to be expected in this price range. A nice feature that none of my other sensors have is the magnet on the back which makes installation MUCH easier. See second photo. All in all you get what you pay for. The lack of a 24 hour high/low record is a deal killer for me. Recommended with reservations.
