These devices have little lights on them that tell you if they are receiving the beam or not. The light will illuminate green if the beam is receiving between the two sensors. If the light is red or orange, then you need to adjust your placement of the sensor to pick up the beam to work properly. The EasyBloom Plant Sensor has received rave reviews with the press. In a January 2009 article titled "Cool News Gizmos For Home, Families, Kids," CBS News writes, "The EasyBloom enables anyone to enjoy a beautiful garden, from a single potted plant to a backyard full of blooms." ABC News recommends this gadget in their December 2008 article "New Home Gadgets for the New Year" and in their May 2009 article "11 Gadgets to Make Her Gush." Barron's chose EasyBloom as their February 2nd, 2009 "Gadget of the Week," with the author writing, "I was impressed with the EasyBloom's secondary functions, which say if plants need watering and diagnose ailing ones." Y The piezoelectric effect is found in some materials (such as quartz) that have an atomic lattice structure forming a rhomboid or cubic cell. When pressure (mechanical stress) is applied to the structure, it produces an electric charge and, when an electric field is applied, a mechanical deformation occurs. "Piezo" is derived from the Greek word for pressure.
