Indoor and outdoor climate monitoring

The U UNNI UN0582 is a wireless thermometer and hygrometer set designed for homeowners, gardeners and pet owners who need to track temperature and humidity across multiple locations from a single display. It includes one indoor console and three outdoor sensors to cover separate rooms, a greenhouse, a garage or a patio simultaneously.

Wireless range and update limits

The sensors transmit up to 330 ft or 100 m line of sight, though walls and interference will reduce the practical indoor range. Readings refresh about every 30 seconds, and daily maximum and minimum records reset automatically every 24 hours. Outdoor temperature and humidity alerts can be set to warn when conditions move outside safe limits for plants, pets or equipment.

Accuracy thresholds that define suitability

Temperature accuracy is ±1.8°F and humidity accuracy is ±5% across a 20% to 95% humidity range. The indoor sensor measures from 14.2°F to 122°F while the outdoor sensors cover -40°F to 158°F, so the system suits typical domestic and garden environments but not extreme industrial or scientific applications.

Questions about this item

Should I use all three sensors at once or start with one?

The package includes three outdoor sensors so you can monitor up to three locations from the single 4.5" display; each sensor pairs independently and updates about every 30 seconds.

What does the ±1.8°F accuracy mean for daily readings?

Temperature readings on the display will stay within 1.8°F of the actual temperature, while humidity readings stay within 5% across the 20%–95% range.

How far can the sensors reach through walls?

Line-of-sight range is 330 ft (100 m); walls and interference will reduce the practical indoor distance.
