Embedded Monitor for Temperature, Humidity and Light

In the whole life cycle management of the agricultural product, the traceability plays an important role for the quality management of the agricultural product. The monitor of the environment such as temperature, humility, and light can used to elevate the traceability of the agricultural product. As the perception layer of the Internet of Things, the monitor is consists of micro control unit of TI MSP430, the sensor of TI HDC1000 and OPT3001, and the microgrids. We designed the system structure, demonstrated the flow diagram of the main program and the interrupt service or handle program.
