Many of us are familiar with motion sensors, as they have become a common part of most home security systems. These sensors are much like the motion detectors that open the doors to the grocery store or cause the sinks and toilets in the airport to activate without touch. We see motion-sensing devices everywhere. But how do they work? There are two basic types of motion detecting systems. There are those with active sensors and those with passive sensors. Active sensors send out ultrasonic sound waves and passive sensors detect infrared energy.
