I am looking for a motorised controller which can alter the 'tilt' of a venetian blind.
The device must be small, battery powered and operate using a daylight sensor.
The venetian blind has two cords which can alter the tilt. One cord rotates the louvers/slats in one direction until closed, the other cord rotates the louvers/slats in the other direction until closed. Pulling a cord in one direction has the opposite effect on the corresponding cord. Neither cord supports any weight. The middle/inflection point between the louvers/slate being closed in one or the other direction represents the ‘open’ position. The louvers should be in the open position during daylight and in the closed position during night time.
Things to consider:
- Tension: continuing to pull the cord when the blind is already closed will damage the blind
- Override: the user may wish to manually adjust the blinds by pulling on either of the cords
- Sensor position: the position of sensor needs to be flexible and window/glass mountable
- Sensor tolerance: does the level of daylight that activates the sensor needs to be adjustable
- Closed: there is one louver/slat fully open position but two louver/slat fully closed positions
- Footprint: particular attention will be given to the size and aesthetic of the solution
- Successful design/manufacture/delivery of 3 devices to a working prototype standard
