U UNNI Indoor Outdoor Wireless Thermometer — 330ft Range, Temperature & Humidity Monitor

Overview of the U UNNI Indoor Outdoor Thermometer

Keep a finger on the pulse of your home and outdoor spaces with the U UNNI wireless thermometer and hygrometer. Designed for real-world use, it combines a compact, backlit display with precise sensing and a robust wireless connection. The system includes a main display unit and a remote outdoor sensor, powered by batteries for flexible placement. Expect clear, actionable readings that help you understand indoor comfort and outdoor conditions at a glance, whether you’re at home, at the office, or away.

The brain of this setup is a Swiss-made high-precision sensor that delivers reliable temperature and humidity data across rooms and exteriors. If you need to monitor multiple zones, the device supports up to three sensors, each feeding back into the same display for a unified climate view. Temperature readings span a wide range, while humidity information is presented with practical accuracy, helping you track seasonal changes, plant needs, or humidity-sensitive spaces such as kitchens, laundry rooms, and basements.

• High-precision sensing with a Swiss-made sensor for accurate readings indoors and outdoors
• Long-range wireless transmission up to 330 feet, updating every 30 seconds to keep data fresh

In daily life, this thermometer helps you spot patterns: cooler mornings in the entryway, muggy basements after rain, or a sunny patio that warms faster than the living room. The backlit screen remains legible in dim conditions, while the molded case in a refreshing green tone blends with home decor. The 330-foot range means you can place the outdoor sensor near a balcony, garage, or greenhouse without losing sight of the numbers on the display.
