Motion Sensor

It is great to attach a motion sensor to the lights so that it can be brighten up only when there is movement. In this way, we can save a little more electricity all the time. Instead of buying a light that is already attached with a motion sensor, we can add this in http://www.sgbotic.com/index.php?dispatch=products.view&product_id=2046. It is used in our multi-story car park and our office staircases.
