HOBYLUBY Sun-Shaped Indoor Outdoor Thermometer Hygrometer, Battery-Free Copper Sensor, Dual °F/°C

The HOBYLUBY Indoor Outdoor Thermometer is a decorative, battery-free dial gauge that measures temperature and humidity for indoor or outdoor use.

Compact and visually distinctive, this HOBYLUBY sun-shaped wall thermometer and hygrometer combines a sensitive copper-driven temperature movement with a clear, easy-to-read dial and a built-in humidity indicator. It’s designed for patios, porches, bedrooms, nurseries and plant areas where a reliable, low-maintenance environmental readout is helpful. The device requires no batteries for temperature sensing and displays both Fahrenheit and Celsius on the same face, simplifying readings at a glance.

How accurate and responsive is the HOBYLUBY thermometer?

The temperature mechanism uses a high-sensitivity copper plate that reacts to slight changes in ambient heat, so it can register new conditions without electronic power. Expect a brief 1–2 hour acclimation period after installation as the dial equilibrates to the location. Humidity readings are provided by an integrated hygrometer for a combined environmental picture.

• Copper plate movement for battery-free temperature sensing
• Dual F°/C° markings on one dial (range: -40°F to 140°F / -40°C to 60°C)
• Built-in hygrometer for relative humidity monitoring
• Allow up to 2 hours for the gauge to stabilize after mounting

Will this thermometer be easy to read from across a room or patio?

The dial is covered by a clear acrylic lens and uses a white background with bold black numerals to maximize contrast and legibility. The sun-inspired silhouette makes the unit visually prominent when mounted on a wall, and the combined Fahrenheit/Celsius scale eliminates switching or conversion steps.

• Acrylic lens reduces glare and protects the dial
• High-contrast white face with bold black numbers for quick reading
• Single dial shows both temperature units simultaneously
• Large, distinctive shape makes it visible from a distance

How does this thermometer fit into home decor and outdoor spaces?

HOBYLUBY designed this piece with style as well as function: the decorative sun shape adds character to patios, entryways and living rooms.

What installation and care should I expect?

Mounting is straightforward—hang on a nail or screw in a sheltered spot away from direct water exposure for best longevity. No batteries are needed for temperature operation, but keep it protected from prolonged direct rain or extreme exposure to preserve the finish and internal hygrometer function.
