| Abstract: | A low-power consumption heat meter based on the MSP430F413 microprocessor was designed. The measurement circuit of flow, the temperature and the circuit of low-power consumption were introduced. In order to reduce power consumption, the running time of CPU was minimized; the floating-point operation was avoided; the operating mode of MSP430 was switched reasonably; and the power supply for modules controlled by IO port was designed specially. The experimental results show that the measurement accuracy is above 2% under low-power consumption. |
