View temperature and humidity levels for 4 locations at once. This wireless weather station includes 3 remote sensors that let you view humidity and temperature readings for 4 locations of your choosing — all in one glance. These sensors can be placed up to 100 meters (328 feet) away from the main unit. Once powered up, the sensors and main unit will start to synchronize within 2 to 3 minutes. Then it will start searching for the atomic radio signal for accurate time/month/date/weekday display. This ultra-slim weather station includes a kickstand and hanging slot, so you can put it anywhere you would like.
