| Abstract: | For bottleneck problem of wireless sensor network energy supply,a kind of wireless sensor network node power sup- ply system is designed based on solar energy. The system has implemented battery charge based on solar energy and discharge pro- tection function,and also,it can automatically detect the output voltage value of solar panels,when it reaches the set threshold,the system＇s power supply will switch to solar panels from battery,through the LDO processing,it can provide a stable power for the node. The test result shows that the system output voltage at 3. 3 V,the average deviation is less than 3%; it can provide continuous and stable power supply for the wireless sensor network nodes in wild. |
