First, the technical parameters: Product Name: Wind rain sensing device operating voltage; DC12V Working frequency: 433.92MHz Working environment: -40 ℃ ~ + 60 ℃ speed adjustment range: 10km / h ~ 50km / h rain flu adjustment range: 1mm / h ~ 100mm / h light sensor adjustment range: 0.2 ~ 10klux wind flu response time: <3 seconds light sensor Response time: 2 minutes rain flu Response time: <25 seconds Second, an overview: wireless system uses rain scenery scenery rain sensor, Receiver , composed of wireless transmitter, and the use of intelligent control chip, to ensure this product is stable, reliable, intelligent hierarchical control windy or rainy weather on the doors and windows closed automatically; can detect wind speed, light intensity and rainfall size, wind sensors by the impeller, wind power motor, wind / power converter composition; light intensity by the light sensor sensing probe, optical coupler composition; rain sensor using gold electrode conductive conduction composition rain; wind speed wind from 2-7 set their own set factory default is 2; the light intensity can be adjusted from a total of five 0.2KLUX to 10KLUX, general factory default is 0.2KLUX; rainfall in size from fog, rain, moderate rain, heavy rain and storm total of five regulation, Usually the factory default is fog; adjustment method, in the back scenery rain sensor, using a flathead screwdriver clockwise rotation, the sensitivity is small, when counterclockwise rotation sensitivity. Three characteristics: Special Material: scenery rain by the anti-corrosion, high temperature, high humidity made of polyamide material, rain or shine; special process: scenery rain unique technology sealed against rain, plus wind feeling part epoxy package and double bearing structure ensures a sense of sensitivity wind; rain sensor surface heat detection face gilt, the second set of conductive outer layer switch built-in double insulation truly safe; 5 adjustable wind speed: 10km / h ~ 50km / h, 10km / h wind force 2, 20km / h wind force 4, 30km / h wind force 5, 40km / h wind 6, 50km / h wind 7 light sensor adjustment range: 0.2 ~ 10klux, 0.2-2-6-8-10 five adjustable rain flu size 5 adjustable: 1mm / h ~ 100mm / h, 1-25-50-75-100 five adjustable 360-degree rotating design: When the windy weather at home, do not want the windows closed, only need to turn the leaves down to the wind sensor
