- Hi,
- I was just curious to know how motion sensors work ? We have one
- installed in our lounge which turns the lights 'On' when someone enters the
- room. If someone moves in the lounge, an LED mounted on the sensor turns on
- and goes off as soon as the movement is stopped - is this a pressure
- transducer at work ?
