Since the sensor energy?saving controller for the photovoltaic power generation has long network latency and unsatisfied energy-saving effect due to the poor energy storage performance of the sensor,a new sensor energy-saving controller for the photovoltaic power generation was designed,and its power supply circuit,wireless communication chip and solar sensor chip were designed emphatically. The wireless communication chip NRF905 is used to monitor the data communication among each device,circuit and component in the controller to ensure the energy-saving effect and shorten the network latency. The power supply circuit supplies the electric energy for the energy-saving work of the controller,and optimizes the energy conversion of so?lar light. The parameters of the optimized solar light energy are extracted and analyzed through the chip TSL2678 in the solar light sensor,which outputs the optimal acquisition orientation of the solar energy and its intensity to realize the optimal energy saving of the photovoltaic power generation. The energy-saving control flow of the controller is given in Fig. 5 in this paper. The analysis experimental results show that the controller has the characteristics of short network latency and good energy?saving effect.
