Abstract :
A Solar-Powered Sensor Module (SPSM) that uses low-cost capacitors as energy buffers to power wireless sensor motes was investigated. Compared to batteries or super capacitors, SPSM is particularly suitable for light-weight tasks since it buffers limited energy and powers up periodically. With our method, the energy charging time can be shortened to about 100 ms for a maximum power point tracking component, and the current of the output regulator can reach 71% efficiency.
