The base station is powered by a 5V 1.2A power supply, which the outdoor sensor requires 3 microcells (AA, recommend using Li-ion batteries). The base station can also be operated alternatively with 3 microcells (AAA, alkaline or Li-ion). Since previous settings will be reset when plugged out, we recommend installing the batteries for the base station. The batteries then serve as a backup e.g. in case of power outages or similar. (Please note: no AAA batteries can be charged with the device.)

Monitor the current and next 12h weather condition Get exclusive weather information in your located area like never before! Easily keep track of indoor&outdoor temperature and humidity, trends, wind gusts, rainfall data and also the weather forecast in 12h. Helps you arrange your day better! Note: We recommend the low-temperature resistant batteries in winter as the performance of normal batteries will be weakened and affect the sensor signal strength when the temperature is below 14℉.	Adjustable Brightness The backlight can be adjusted to 3 brightness levels by touching the top “Snooze/Light” key, and can also set a time period for auto dim mode, which meets different needs when using.	High-low Alerts The WF-100C Lite is able to set up custom alarm values for high/low temperature, humidity feels like temperature, rainfall, wind, air pressure, dew point, etc. When conditions exceed your preset values, the console will alert you. An invaluable tool in natural disaster-prone areas (hurricane/tornado/wildfire).
