TempPro Wireless Indoor Outdoor Thermometers let you monitor temperature and humidity inside and out. Precise temp and humidity sensors for every space.
A wireless indoor outdoor thermometer pairs an indoor display with one or more remote sensors, so you see the temperature and humidity both inside your home and outside, all on one screen, without stepping out the door. Place a sensor on the patio, in the greenhouse, in the nursery, or in the garage, and the base station shows you each reading in real time. If you garden, brew, keep reptiles or wine, watch a baby's room, or just want to know the real outdoor conditions before you head out, it saves you the trip and the guesswork.
Pick by screen, range, and accuracy:
Biggest, easiest to read (Best Seller):TP65B — jumbo 4-inch touchscreen, backlight, comfort indicator, 24-hour/all-time records.
Best value entry:TP60B covers the basics on a large 2.7-inch display.
Longest range, highest accuracy:TP260B doubles range to 1,000 ft with a Swiss ±0.5°F sensor, for large properties or wine cellars.
Rugged with backlight:TP62B — 500-ft range, lit display, tough weatherproof sensor for decks and gardens.
Complete multi-zone kit:TP220B includes 3 sensors out of the box, monitoring four locations from day one.
Most models reach 500 ft in open air, which comfortably covers a typical yard, patio, or greenhouse from an indoor base. For larger properties, more walls, or a detached garage or workshop, the TP260B doubles that to a market-leading 1,000 ft with stronger signal penetration through floors and obstacles. One honest note: walls, metal, and distance all reduce real-world range, so if the sensor sits far away or behind thick walls, the 1,000-ft TP260B is the safer bet.
Accurate enough to trust for the decisions that matter. The standard models read to within about ±2°F and ±2-3% RH and refresh every 10 to 30 seconds, while the TP260B steps up to a Swiss-made Sensirion sensor accurate to ±0.5°F, the tightest in the lineup, for wine cellars, nurseries, or anywhere precision counts. All models show high and low records and trend arrows, so you can see at a glance whether conditions are rising or falling.
Yes! And this is where these really shine. Every base station expands to up to 3 remote sensors, letting you track 4 locations at once on a single screen, say the living room, the greenhouse, the nursery, and outside. The TP220Bincludes all 3 sensors in the box, while on other models the extra sensors are sold separately so you can start with one and grow. Each sensor sits on its own channel, so readings never get mixed up.
Yes! The remote sensors are weatherproof and cold-resistant, rated to keep working from well below freezing up to 158°F, so they hold up to rain, snow, summer heat, and everything in between on a deck, in a garden, or on a shaded patio. For the longest outdoor life, mount the sensor out of direct rain and direct sun, which also keeps the readings most accurate. Built to live outside year-round, it just keeps reporting.
No. These are refreshingly simple: the sensor and base station sync automatically over their own radio signal, so there's no app to download, no account, no Wi-Fi to configure, and no hub to buy. Just put in the batteries, place the sensor, and read the screen. That also means no dropped connections and no phone battery drain, and anyone in the house can glance at the display without logging in.
A wireless indoor outdoor model adds remote sensors so you see inside and outside, or several rooms, on one screen, with no app.
A weather station goes further, adding forecasts, barometric pressure, and often an atomic clock.
If you just want accurate current readings from multiple spots without your phone, this category is the sweet spot. Want your readings on your phone instead? Our Bluetooth indoor outdoor line does that.
For most homes, this is more than enough. You get accurate indoor and outdoor readings, expandable multi-room sensors, and long wireless range, all with no app, no subscription, and nothing to pair, usually at a friendlier price than connected models. Step up to Wi-Fi or Bluetooth only if you specifically want to check conditions while you're away from home or get alerts on your phone. If you mainly want to glance at a screen and know your climate inside and out, a wireless model like the best-selling TP65B does exactly that.
TempPro (formerly ThermoPro) has sold millions of thermometers and hygrometers and is trusted for accurate, affordable home monitoring. Our wireless indoor/outdoor models pair long-range RF with weatherproof expandable sensors, high/low records, and no-app simplicity, and the TP260B adds Swiss-sensor accuracy and a 1,000-ft range.
