The Study of Low-Power Consumption Heat Meter Based on MSP430
A low-power consumption heat meter with long-distance communication was designed based on MSP430F413 and TDC-GP2. The new flow measurement circuit and correction method were introduced in detail, which improved the accuracy of the heat meter effectively. In order to reduce the power consumption, the running time of the CPU was minimized, the floating-point operation was avoided, and the communication circuit was designed specially. The experiments showed the design is valid.
