Bioreactor Environment Monitor & Controller
Build a benchtop bioreactor monitor: control and log temperature, pH, and dissolved-oxygen proxy for cell-culture conditions. Hold setpoints with a heater and pump. Highly relevant to biotech/biomanufacturing roles. NOTE: Educational project only. NOT a medical device and not for clinical or diagnostic use.

Steps
- Set up a benchtop vessel with the pH sensor, temperature probe, heater pad, and air pump.
- Calibrate the pH sensor with buffer solutions.
- Program the Arduino to log temperature and pH to the microSD card.
- Add control logic that switches the heater and pump to hold your setpoints.
- Run the system for 24 hours or more and measure how well it holds setpoints.
- Chart the results and document the controller for your portfolio.
What to photograph for your portfolio
