Abstract:
    The system consists of the photo-volt battery (PV), the lithium ion batter (LI), the energy source management module (ESM) and the transducer node (TN). ESM includes all electrical ports used to connect PV, LI and TN. After PV, LI and TN being connected to the defined ends of ESM, PV produces the energy under enough illumination and supplies power to TN and charges simultaneously LI via ESM. In case the illumination is poor, LI supplies power for TN. The self-supplied micro-system integrated from PV and TN can extend TN working life without maintenance, i.e. replacing or charging batteries. Therefore, the invention solves the bottleneck problem of the energy source for TN.
