Termómetros Bluetooth para interiores y exteriores

A Bluetooth thermometer hygrometer measures the temperature and humidity of a space and sends the readings straight to an app on your phone, so you get trend graphs, historical data, and custom alerts instead of just a number on a screen. Place one in the nursery, greenhouse, wine cellar, humidor, or garage, and your phone shows you what's happening and warns you before conditions drift too far. If you want to track patterns over time, protect sensitive items, or get a heads-up when a room gets too dry or damp, the app makes all of that effortless.

Pick by precision, display, and size:

• Most accurate, reads records on the device (Best Seller): the TP359 uses a Swiss ±0.5°F sensor and is the only model showing high/low records on its 3.5-inch backlit screen, for a wine cellar, nursery, or instrument room without opening the app.
• Smallest and most affordable: the TP357 tucks into a humidor, reptile tank, or wine shelf, and stores a year of data.
• Clock plus backlight: the TP358 is the only one with a built-in clock and date on a 3-inch backlit screen, with 2 years of exportable data.

No, and that's a real advantage. These connect directly to your phone over Bluetooth, so there's no Wi-Fi to configure, no account to create, and no personal data collected. You just download the TempPro Sensor app, pair, and you're monitoring in under a minute. Unlike many smart hygrometers that route your data through a cloud account, TempPro keeps everything local and private, which also means setup is faster and there's nothing to get hacked or locked out of.

The range is a stable 260 feet in open space, plenty to reach across a house, into the backyard, or out to a greenhouse. Here's the honest part: Bluetooth works when your phone is within that range, so you can't check it from across town like a Wi-Fi device. What it does instead is keep logging while you're away, then automatically sync all the missed data to your app the moment you come back within range. So you never lose history, you just view it when you're home. If checking from anywhere is essential, that's what a Wi-Fi model is for.

Quite a lot, and it's the main reason to go Bluetooth. The TempPro Sensor app plots dynamic trend graphs so you can see how a room's temperature and humidity move across a day, a week, or a full year, and models like the TP359 and TP358 store up to two years of history you can export for your records. You can also set custom high and low thresholds, and the app pushes a notification the moment conditions drift outside them, catching a dropping humidor or an overheating greenhouse before any damage is done.

Yes! The app holds several sensors at once, so you can place one indoors, one in the greenhouse, and one outside on a covered patio, then see all of them together on your phone. That's how these cover indoor and outdoor at the same time, by pairing multiple affordable units rather than running wires. It's a flexible, low-cost way to build out whole-home and hobby monitoring one sensor at a time.

Accuracy runs from ±0.9°F on the standard models to ±0.5°F on the best-selling Swiss-sensor TP359, tight enough for wine, instruments, or a nursery where small changes matter, and all read humidity to within ±2% RH. Most models show the current temperature, humidity, and a comfort icon right on the device, and a couple go further: the TP358 adds a clock on a backlit screen, and the TP359 uniquely displays high and low records on the device itself, so you don't always have to reach for your phone.

A standalone hygrometer shows readings on its own screen with no app. A wireless indoor outdoor model uses a base station and remote sensors over radio, with no phone at all. A Bluetooth model like these sends everything to your phone for graphs, history, and alerts. A weather station adds forecasts and barometric pressure on top. Choose Bluetooth if you want app data and phone notifications without Wi-Fi, and look at our wireless line if you'd rather read a base station, or the weather station line if you want forecasting.

For most people, Bluetooth is the sweet spot. You get app graphs, history, and custom alerts, all while keeping your data private with no account and no Wi-Fi setup, usually at a lower price than connected smart monitors. The one thing Bluetooth won't do is let you check conditions while you're miles from home, since it needs your phone in range, though it logs and syncs everything when you return. If remote-from-anywhere access is a must, step up to a Wi-Fi model, otherwise a Bluetooth model like the best-selling TP359 gives you the smart features that actually matter day to day.
