Design of the intelligent heat meter based on MSP430FW425
This paper describes an optimized hardware and software design for the heat meter. It is equipped with the international popular low-power consumption single-chip microcontroller MSP430FW425, temperature sensor Pt1000, impeller flow meter and zero energy-consuming magnetic sensor. They improve the precision and sensitivity of heat measurement. It also concludes the RFID module which has realized the function of advance payment.
