A wireless thermometer and hygrometer designed to deliver accurate readings in various environments. Equipped with a high-precision sensor, it captures subtle temperature and humidity changes, maintaining readings within 0.5°F and 2% RH. It comes pre-calibrated for initial accuracy and allows manual calibration if affected by external factors. The device supports connecting up to 3 wireless sensors, enabling monitoring of up to 4 locations (up to 200 ft. apart), ideal for whole-home, storeroom, or greenhouse use. It tracks the highest and lowest temperatures and humidity over the past 24 hours or all time, with a comfort indicator to quickly assess if conditions deviate from ideal levels. A 3.5 in. HD LCD screen with a touch-top backlight ensures easy reading, and the backlit is not always on for energy efficiency. With a retractable stand, magnets, and wall-mount options, it can be placed in baby rooms, closets, greenhouses, offices, and more, adapting to any space.
