Indoor/Outdoor Thermo-Hygrometer Combo

I was skeptical about placing it in the bathroom, but the IP65 waterproofing has held up perfectly through months of steamy showers. The display is easy to read from across the room, and it's been spot-on for keeping an eye on humidity levels in my guitar case too.

The IP65 rating is a lifesaver—I've got mine hanging right by the bathroom sink and it hasn't fogged up or glitched once. The display is easy to read from across the room, and it's been spot-on for keeping my humidor at the right level.

Set it up in the greenhouse and the roof garden both, since the IP65 rating means rain and hose spray aren't an issue. The readout is clear even in direct sun, and it's nice to finally have one unit that tracks both humidity and temperature to keep my seedlings happy.
