Design of the Environment Multi-parameters Recorder Based on MSP430 SCM

摘要

The paper selected reasonable sensitive parameters for detecting and designed environment multi-parameters recorder with MSP430 SCM, which is the core of the recorder. It can realize to test, display, and store data in the Nonvolatile Ferroelectric Random Access Memory FM31256, even if the power of the system is shut off, the data does not lose. Utilizing Multi-parameters recorder, it can measure strength of four kinds of environment parameters, which include temperature, humidity, illumination and the concentration of carbon dioxide at the same time, and also can detect one kind parameter in four kinds of parameters. Using the interface chip CH375 which supported USB host-device mode, it can communicate with flash memory disk or PC, conveniences the using for different people in different situations.
