TempPro TempAir 500 FT Wireless Indoor/Outdoor Thermometer with 3 Sensors — Temp/Humidity, 500 ft Range

The TempPro TempAir 500 FT is a wireless indoor/outdoor thermometer that displays temperature, humidity, and trends from up to three remote sensors across a 500-foot range.

Whether you need to track conditions in a nursery, greenhouse, cellar, or multiple rooms, the TempAir 500 FT gives simultaneous temperature and humidity readings on a tabletop or wall-mounted console. It ships with three wireless sensors, records max/min values, and uses trend arrows to show whether conditions are rising or falling. The system runs on common AAA batteries and supports extra sensors for broader coverage.

How far can the sensors transmit, and where should I place them?

The sensors transmit reliably up to 500 feet (about 150 meters) in open space; actual range varies with walls and interference. Place sensors where you want continuous monitoring—near HVAC vents, in a nursery, or in a backyard shed—avoiding dense metal or thick concrete between sensors and the console.

• Rated wireless range: 500 ft / 150 m line-of-sight
• Works through typical interior walls; heavy obstruction reduces range
• Tabletop console or wall-mount for flexible placement
• Additional sensors can be added to expand coverage

What measurements and records does the TempAir 500 FT provide?

The console displays indoor and outdoor temperature and humidity simultaneously, plus all-time and 24-hour maximum and minimum records. Temperature range is -4°F to 158°F (-20°C to 70°C) and humidity measures from 10% to 99% RH, with trend arrows indicating warming or cooling.

• Temperature range: -4°F to 158°F (-20°C to 70°C)
• Humidity range: 10% to 99% relative humidity
• Max & min records: all-time and 24-hour values
• Trend arrows show rising, falling, or steady conditions

How many sensors can I use and how is the system powered?

The system supports up to three sensors out of the box, and additional TempPro sensors can be paired for more locations. The console and sensors run on AAA batteries (the package includes eight), making installation cable-free and simple.

• Includes three wireless temperature/humidity sensors
• Expandable: compatible with additional TempPro sensors
• Battery-powered: uses AAA batteries (8 included)
• Mounting options: freestanding console or wall-mounted sensor placement
