LCD DIGITAL DISPLAY The R7 has an upgraded LCD digital display that easily displays the current channel number, temperature and humidity. In addition, it supports both ℃ and ℉ switches, making it easy to read in your preferred unit of measurement. Compatible with models: home weather station N75, N80; pool thermometer PT-3. Powered by replaceable 2 x AA batteries (not included), which you can easily find on the market. Wireless transmission distance: this remote control sensor has a range of up to 100 m (330 ft) in an open area. To ensure proper synchronization, insert the battery into the main unit before inserting the battery into the remote control sensor. Temperature and humidity range: Temperature: -40℉ to 140℉ (-40℃ to 60℃); Humidity: 1% to 99%. We recommend using cold-resistant batteries in winter, as the performance of normal batteries is weakened at temperatures below 14°F (-10°C) and affects the sensor signal strength. Note: we recommend ①placing the remote control sensor upright ②place outdoors with a guard ③away from interference sources ④ at least 4 feet from the ground.
