Due to the traditional WSN chip used universal translation processor and the embedded software implemented through the WSN communication protocol, the power budget management is only on processor level and algorithm level. In this article we focus on the home wireless sensor network applications which adopted the simple WSN communication protocol and a low-power loss wireless sensor controller. The WSN controller is made by fully hardware electric circuit to avoid using the piling up software on top of controller. It not only can reduce the system power loss efficiency, but also can reduce the system complexity. WSN tends to get smaller size, lower cost and lower-power loss. This paper is about the methodology of software in MIAT and MIAT C3X25 tests the version for testing WSN Controller chip’s platform according to Altera Cyclone III FPGA. Besides, it arranged to the Nordic nRF24L01 2.4GHz RF and proceeded with conformity confirmation. What I mentioned above, the experimental result is compared with the traditional data transmission that can reduce the number of transmission times, promote the transmission efficiency and save the power consumption. Finally, it is an advantage for our WSN controller that is simple, low power and high efficiency
