Supporting sensor application over wireless sensor node (WSN) is more challenging than over any other sensor due to the absence of a convenient way to maintenance the sensor node, especially in changing of energy source (batteries). In this paper, we solve this problem by using the ambient energy source (solar), design the efficient power conversion, and low-power consumption in WSN system. Some modifications have been introduced considering the differences between wired and wireless network. The modifications also consider the differences wide of WSN for detection. Simulation study is carried out using PSPICE to demonstrate the performance of the power conversion mechanism. MPLAB is used for the proposed logical control (PIC). We show that the proposed mechanism outperforms the wireless sensor node reception and transmission in every situation (different levels of darkness).
