Abstract
An awning control system provides automatic retraction of an extended awning upon detection of awning motion in multiple dimensions caused by windy conditions. The awning control system includes a micro-electro-mechanical system (MEMS)-based accelerometer for motion-based auto-retraction. A single, combined motion sensor/controller module may be located in the motor head and connected to switches and a 12V power source through wires routed along or within the awning framework. The control system operates by gauging the vertical, horizontal (inward/outward), and lateral motion of the leading edge or lead rail of the awning when in a fully or partially extended position. When persistent motion or gust exceeds preset thresholds, the control system will automatically engage the motor to retract the awning. The control system provides full automatic retraction of the awning unless halted or interrupted by additional user input. Manual switching also controls the extension and retraction of the awning.
