GreenPatch: An ultra-low-power energy self-sustained sensor
GreenPach is an energy self-sustained sensor which uses the ultra-low-power sensing technology developed by Resensys. It harvests the indoor ambient light energy to power itself through a solar panel. Most sensing capabilities such as temperature, humidity, acceleration, and so on can be integrated in the module. Pictures below show the new design on the flex PCB board which has the human presence sensor integrated.
