I just saw a commercial for the new Glade air freshener with a built in motion detector. Anyone open one of these yet?

The helpful hints says:

The sensor may not respond if:
* The room is too dark. Ensure there's sufficient lighting to allow a shadow to be cast upon sensor.
* The unit is placed directly on or in a light source, especially sunlight. Move the unit out of the bright light.
* Sensor on the front of the device is blocked by objects. Position the unit so that the sensor is unobstructed.

So does that mean it's just using a CDS cell?

    Probably a phototransistor. It's just looking for sudden changes in light level.

    CdS cells aren't allowed in the EU (RoHS). It must be a photo-transistor.
