The goal of our project is to solve the CO2 problem by using engineered E.coli to fix carbon dioxide emitted from industries and convert it into bio-product, pyruvate. To accomplish our goal, we designed a device that will upscale our project to be used on field and we aim to integrate the device into industrial IGCC system. And we used the Arduino to sense the pH(連結到hardware pH), CO2 concentration(連結到hardware CO2) and temperature(連結到hardware temperature ) then use the wi-fi sensor(連結到hardware WIFI) to upload to the database. (連結到software database)Last but not least, we can monitor the data by our app.(連結到software app)</p> |

Thus, we reduce CO2 concentration level to less than 5% before entering the bioreactor by using flowmeter, which is an instrument for measuring the flow of gases in pipelines.</p> |

As low concentration CO2 enters the bioreactor, it flows through the diffuser refiner and dissolves in the buffered medium to form acid. A pH sensor and temperature sensor is installed to monitor the bioreactor tank for further control implementation. Besides, the CO2 concentration level of exhaust gas is monitored by a CO2 gas sensor, which is mounted on the upper lid. These sensor’s output is connected to an Arduino analog input and sensor readings are displayed on a serial LCD which is attached on the lid of bioreactor. The data is then uploaded in real time to a web server via WiFi by using Arduino WiFi Shield.</p> |
