This invention relates to a retractable and extendable awning and a control system for automatically extending and retracting the awning. In a retractable fabric awning a front of the awning fabric is attached to a movable front bar, movably mounted at the wall of a building by retractable arms. The rear of the fabric is unrolled from a roll of the fabric on the building wall when the arms move the front bar away from the building. The awning features a weather sensor unit on its front bar. The weather sensor unit can detect excessive wind and mechanical shocks and also sunlight and rain. The sensor is in wireless (via radio frequency) communication with an indoor control unit which can automatically retract the front bar during windy, rainy and/or low sunlight conditions and extend the front bar during calm and sunny conditions.
Control system for a sun protection device including in combination a sensor unit, comprising at least one sensor, and a control unit for controlling the sun protection device, wherein the sensor unit is provided with a solar cell and a rechargeable battery as a sole means of power supply, the solar cell and the rechargeable battery being coupled by a charging circuit, the charging circuit including a step-up converter, and wherein the sensor unit and the control unit communicate with one another by means of wireless signal transmission for moving the sun protection device between retracted and extended positions.
A Control system for a sun protection device including in combination a sensor unit, comprising at least one sensor, and a control unit for controlling the sun protection device, the sensor unit including a solar cell and a rechargeable battery as a sole means of power supply, the sensor unit and the control unit being configured to transmit wireless signals between one another for the purpose of moving the sun protection device between retracted and extended positions, wherein the sensor unit transmits a wireless signal to the control unit at predetermined periodic intervals.
