Abstract

In order to reduce the nodes power consumption of wireless sensor network (WSN), the lower power consumption design tactic of WSN nodes is described about low-power hardware design and low-power energy management of the sensor node. Include the parts of an apparatus choosing principle for sensor, single chip and wireless communication module etc. The method and measure about debasing single chip voltage and frequency, increase the wireless communication module sleeping time, decrease the software running time etc. Some deficient side is indicated also. A hardware design is described about WSN node of intellectualized power saving greenhouse. It is made up of CC2420 wireless communication module. The testing shows the WSN nodes works stead. The performance of lower power consumption is prominent.
