Week 21

The team ordered two sets of color sensors last weekend, and they arrived on Tuesday. The team is meeting tonight to test the sensors and write basic codes in Arduino. The team contacted Dr. Chet Hammill during the week to obtain two plastic drainage bulb. The next step will be implement all the sensors into the original drainage system to test the functions. The team also decide to 3-D print a larger bulb for the demo.

Week 20

The team met on Sunday to test the sensors, assemble the final product, and code in Arduino. The team confirmed that the volumetric sensor measuring fluid levels worked perfectly. The sensor was able to detect different fluid levels and initiate an alarm when the liquid level reaches a certain point. The buzzer also worked well. The next step will be integrating our color sensor to detect blood if it presents in the fluid. The team is meeting today again to test the e-tape fluid sensor, which is an alternative choice to measure fluid level.

Week 19

The team scheduled a group meeting on Sunday afternoon to test the 2 volumetric sensors and buzzer. After checking the sensors, the team will start to assemble the Arduino board and write the finished Arduino code.

Due to convenience concerns, the team also discussed the possibility of replacing the pH sensor with a thermometer. Having discussed with our client via email on the standard system for temperature monitoring, the team had some ideas on monitoring the temperature of patient’s fluid if infections occurred.
