Embodiment Construction
[0027] The drawings are only used for exemplary description, but the embodiments of the present invention are not limited thereto;
[0028] The technical solution of the present invention will be further described below with reference to the drawings and embodiments.
[0029] Such as figure 1 , A wireless sensor network node power management circuit suitable for energy harvesting technology, including a front-stage energy storage module, a boost module, a rear-stage energy storage module, a control circuit module, and an application circuit module;
[0030] The front-stage energy storage module stores the energy collected by environmental energy harvesting technology as the input power supply of the boost module, and provides a stable current when the load of the back-stage boost circuit changes greatly;
[0031] The energy of the front-stage energy storage module is weak, and the voltage amplitude is low, and the voltage amplitude is increased to the working voltage value of the subse...
