The DuoFern sun/wind sensor is a radio-enabled sensor for controlling sun protection. It enables brightness- or wind-dependent control of up to 3 registered DuoFern receivers such as awnings or roller shutters. If the individually set limit is exceeded, the sensor sends a radio command to the registered receivers (max. 3). All parameters can be easily set using the control buttons and the display on the device. Powered by a solar cell with an integrated battery, it can be installed and put into operation quickly and easily. The sensor has a test function for wind and sun for quick and safe commissioning.
