The smart WS40WH weather station with three wireless sensors measures temperature and humidity at multiple locations simultaneously, displays absolute atmospheric pressure, temperature and humidity trends, a 12–24 h forecast, Moon phases, and includes a clock, calendar, and alarm. Powered via adapter or batteries.
Keep track of the climate indoors and outdoors. WS40WH has a built-in indoor sensor and three separate wireless sensors with LCD that you can place in the garden, bedroom, or garage. The clear color display shows all four data sources at once, min and max with automatic daily reset, and °C/°F selection.
The station offers a graphical weather forecast for 12–24 hours based on pressure changes, indicators of temperature and humidity trends, display of absolute pressure, and Moon phases. It also features a clock (12/24 h), a calendar in several languages, an alarm with snooze, and backlight dimming with scheduling options.
Power is flexible: the main unit runs via a 5 V / 1200 mA power adapter or on AA batteries (for settings backup or off-grid operation). The outdoor sensors are powered by the supplied AA batteries, with their charge status shown on the display. You can stand the device on a table or hang it on a wall; install sensors in the shade, protected from rain and wind.
