| Abstract: | A carbon dioxide capture system takes MSP430F169 of Texas Instruments as the main controlling chip, and it uses M（;811 carbon dioxide gas sensing probe to detect carbon dioxide gas concentration. The capture system displays the carbon dioxide concentra-tion data through segment LCD drove by HT1621, and the system has external expansion M25P80 chip to save the measurement data storage that can communicate with PC through USB. Tests show that the system works stable, simple structure, easy to carry, with good promotion prospects. |
