| Abstract: | The power supply is very important in the whole wireless sensor network system. In order to meet the sys- tem for micro sensor nodes power requirements, this paper designs the realization of ultra low pressure pump start charging, the double capacitor energy storage, the two PSA weak energy acquisition circuit. The circuit can provide energy storage circuit of energy accumulation in the conditions of low temperature difference, realize energy acquisition of weak temperature, and prepare lastly for power supply according to the characteristics of wireless sensor nodes intermittent work. |
