The rain detector can be used to automatically control the operation of awnings or skylights, for example. The switching polarity and sensitivity are adjustable. In the most sensitive setting, the device is also suitable for detecting fog. The pole or wall bracket, available as an accessory, enables simple installation.re-design: The sensor surface has been optimised to increase reliability in difficult operating conditions (e.g. driving rain). To ensure this, the tips of the sensor surface no longer run vertically downwards, but at an 80° angle. In addition, the individual areas of the sensor surface are now significantly narrower and therefore detect rain and snow more reliably. In addition to the optimised sensor surface, automatic activation of the sensor heating has also been integrated. This is only active when the sensor surface is wet and is used to quickly dry the sensor surface and remove snow residue. In addition, there is now an adjustable switch-off delay in the rain detector. This can be individually set to approx. 90 to 330 seconds, depending on requirements.
