Best Outdoor Thermometer Wireless: 10 Models Compared

#1 · Best Overall

1. TempPro TempAir 500 FT

Best for: Long-range home monitoring.

Why it ranks #1: Its stated 500-foot range, indoor/outdoor temperature and humidity readings, 24-hour and all-time highs and lows, and 30-second updates suit everyday home monitoring.

A stated 500-foot wireless range lets the TempPro TempAir 500 FT relay outdoor readings from farther across a property than many home setups require. Its display combines indoor and outdoor temperature and humidity, so you can check both environments from one tabletop or wall-mounted unit.

The 3.1-by-2.6-inch LCD uses bold, easy-to-read readings, making a quick check practical from across a room. Measurements update every 30 seconds, while trend indicators and all-time or 24-hour highs and lows help you notice changes without keeping your own log. Temperature and humidity monitoring covers both locations, and the tabletop or wall-mountable design gives you a choice of where the main display lives. The supplied 4 AAA batteries help get the unit started.

Skip it if you need readings from several outdoor locations; the U UNNI UN0582 lists three-sensor data display.

Choose the TempPro if you want to check indoor and outdoor temperature and humidity from a display placed well away from its sensor. Its 500-foot range is the key fit, while the listed one-sensor setup limits multi-location monitoring.
