1DESIGN CONCEPT: The weather forecast application actually reports the weather based on data from a weather station several miles from the current location, which almost inevitably leads to differences in temperature and humidity. 2ACCURATE DATA: Compared to a weather station far away from your location, a wireless home thermometer in your home will collect more accurate data and provide more accurate results. 3ELEGANT DESIGN: The thermometer and hygrometer use the same color, but with a larger and clearer display and a clean cut part. Careful color matching provides better and easier viewing of indoor and outdoor temperature and humidity readings. 4DIGITAL DISPLAY: Whether you place it on the table or on the wall, no matter what happens, the wireless thermometer is always with you, displaying everything you need to know on the bright digital display. 5WIDE RANGE OF USE: The line of sight of the wireless sensor can achieve 328 feet (100 feet in most cases). You can control the bedroom, living room, nursery, kitchen, office, terrace, greenhouse, camping trailer, chicken house, garage, etc. in real time.
