The low-power consumption design of the system is studied to meet the requirements of the small-volume battery self-powered supply of the wireless temperature detection system.The structure and working principle of the self-powered wireless temperature detection system are analyzed.The technique schemes of signal processing circuit shutoff controlled by the MOSFET-SI2302,switching between the working mode and sleeping mode of master chip,and switching between working mode and sleeping mode of the wireless data transmission module are coordinated to accomplish the low-power consumption design of the system.The circuit simulation software Proteus is used for simulation experiment of circuit power consumption.The experimental results verify that the three low-power consumption design schemes proposed in this paper can reduce the power consumption of the system,and solve the self-powered supply problem of the small-volume battery in the wireless temperature detection system.
