Rain Sensor automates window and vent closing.
Press Release Summary:
Jan 16, 2013 - Based on same principle used in automotive windshield wiper control systems, RG-11 Optical Rain Gauge is sensitive to even tiny amounts of rain,Â and stops sensing when rain stops, without having to wait for water to evaporate. Device may be set as On/Off indicator or used to emulate tipping bucket where qualitative measurement of rainfall rate is desired. Immune to external contaminants, sensor is suitable for greenhouses, agriculture, and louver vents.

New Rain Sensor for Automated Window and Vent Closing
Press release date: Jan 11, 2013
The RG-11 Rain Gauge is an optical sensor, and is sensitive to even tiny amounts of rain. In contrast, rain sensors used in irrigation do not detect rain until several millimeters have already fallen. That is far too insensitive for most window-closing applications. Further, and in contrast to other sensing technologies, the RG-11 stops sensing rain when the rain stops. It does not need to wait for the water to evaporate.
The Hydreon RG-11 is based on the same principle used in automotive windshield wiper control system. Consequently, it is immune to external contaminants, a problem which plagues conductive rain sensors. DIP switches within the device set the sensitivity, and the RG-11 can be set to various modes of operation. The device may be set as a simple on/off "it's raining" indicator, or used to emulate a tipping bucket where qualitative measurement of rainfall rate is desired. Interfacing is through simple relay contacts. The RG-11 costs $49.00 each in quantity of 3. Further information is available at www.rainsensors.com.
