Easy-to-Read LCD Display: Featuring an LCD digital display, the R4 shows the current channel number, temperature, and humidity. It supports both ℃ and ℉, making it easy to read.

Wireless Transmission Range: Insert the battery into the main unit before the remote sensor to ensure proper synchronization. The remote sensor has a wireless transmission range of up to 330ft (100m) in an open area.

Temperature and Humidity Range: The ranges of the sensor are -44°F (-40°C) to 158°F (70°C) and 20%RH to 95%RH respectively. During winter, when the temperature is below 14℉ (-10℃), we recommend using low-temperature resistant batteries as normal batteries may weaken and affect the sensor signal strength.

Two Mounting OptionsOur digital weather station sensor can be placed on a shelf or hung on a wall, making it versatile and convenient. 

Note: We recommend ① place the remote sensor upright ② place it outdoors with a shelter ③ make it far from interfering sources ④ put it at least 47 inches (1.2m) from the ground.
