TempPro TempAir Bluetooth Hygrometer Thermometer — 3.5" Backlit LCD, 260 ft Range, 2-Year Data

The TempPro TempAir is a Bluetooth-enabled indoor hygrometer and thermometer with a large backlit LCD, 260 ft wireless range, and two years of exportable data for precise home climate tracking.

Monitor temperature and humidity across rooms with a single device that pairs to a phone app for real-time readings, alerts, and historical charts. TempPro built this unit for accuracy and visibility: a sensitive NTC sensor captures small fluctuations, while the 3.5-inch soft yellow backlit screen makes readings readable without harsh glare. The integrated Bluetooth 5.0 connection reaches up to 260 feet (80 m) in clear conditions and the app stores and exports up to two years of logged measurements for trend analysis.

How accurate are the temperature and humidity readings?

The TempAir uses a high-precision NTC temperature sensor with an accuracy of +/-0.9°F and a humidity tolerance of +/-2% RH. That level of precision is suitable for home HVAC monitoring, greenhouses, wine cellars, and other environments where small changes matter. The device updates in real time through the app so you can catch quick shifts.

• Temperature accuracy: +/-0.9°F for reliable indoor readings
• Humidity accuracy: +/-2% RH for precise moisture tracking
• Sensitive sensor picks up subtle environmental changes

How does the Bluetooth connectivity and app help me manage conditions?

The Bluetooth 5.0 radio gives a dependable wireless range up to 260 ft (80 m) in open space, letting you check conditions from another room or floor. The companion app displays dynamic temperature and humidity graphs, issues instant alerts when presets are exceeded, and allows exporting up to two years of logged data. Real-time push notifications help you respond to excursions quickly.
