Researchers at the University of Arkansas and the University of Michigan have reported the first use of ultra-low power temperature sensors using graphene-based solar cells. The test is the first ...

More of my EV kick coming through. A solar tracker is used rotate a solar panel to get optimum energy from the sun. This one uses LEDs as the light sensor and mosfets to drive the output to rotate on ...

One of the biggest challenges for wireless sensor networks is that of power. Solar panels usually produce less power than you hoped, especially small ones, and designing super low power circuits is ...
