The sensor testing champers
Inspiration
Inspired from the blood glucose monitor.
What it does
A convenient device for blood typing. Show the blood type, donors, and recipients after analyzing one blood drop.
How we built it
We have not build the project sensor but we have a scientific explanation and a prototype design below: The sensor will consist of 3 testing champers. There will be a different antibody type in each chamber which are anti-A, anti-B, and anti-D. Each camber will have wires connected to them from two sides. When a person puts a blood drop in the sensor, it will be distributed to the three champers and the device will generate a current in the wires that will go through the champers. The current flow will be monitored to detect if an agglutination happened in each chamber. An analyzation will be done for the three champers output current to determine the blood type.
The chip sensor will be for one time use only and it will be attachable to the main device. The figure below shows the chip sensor. PCB
We used an arduino (TTGO T1 Display) to analyze the data. The sensor output is represented as a boolean value and we demonstrated that in the arduino build.
Challenges we ran into
Research if the sensor idea is applicable.
Design the sensor prototype.
Accomplishments that we're proud of
The successful arduino project that reflect the device implementation.
What we learned
How blood typing is done. How to use and program TTGO.
What's next for Blood Typing Device
Building an actual sensor, and testing its efficiency.
