Wireless sensor networks have been widely used in various fields. This paper introduces the hardware design and the program design for reducing the energy consumption of sensor nodes and prolonging the use time of the battery. The mathematical model of the sleep time and energy consumption is established, and the relationship between the two is quantitative analysised. At the same time, combined with the experimental results, it is indicated that the application of this prediction model can provide a simple long time estimation for the use of batteries.
