TING's final project

Project Development

Final Project Timeline

Due to Covid-19, the original plan was changed and a new project gantt chart (version 2) was developed. SP Fablab was opened only from 8 June and due to long closure, several machineries need servicing and conditioning as such there were further delays. One serious delay was the unexpected difficulty in getting the AT-09 Bluetooth BLE module to transmit data to the smartphone. AT-09 is a clone of HM-10 and while listed as compatible, some tweeting are required. After consulting with my local coaches, I decided to try HC-04. Using this module, I was able eventually able to get my board to transmit data to the smartphone.

The actual project timeline is shown below:

Reflections

1. What tasks have been completed? What task remains?

The MFC biosensor is able to work as per design. The pump is able to turn on and off according to the designated timing to bring fresh solution to the anodic chamber. THe MFC is able to produce a voltage which is dependent on the conditions of the solution in the anodic chamber. The data can be transmitted via Bluetooth to a smartphone. THe Android app created using MIT App Inventor is able to work properly. All the tasks were completed.

2. What has work, what hasn't?

As discussed above, all the parts function nicelt as per designed. One area however needs improvement.

3. What will happen when??

This first prototype can work properly however the data acquired by the biosensor can only be transmitted to the user when the distance is less than 10 meters. Also, the user has to turn on the Andriod app on the smartphone. A more useful design would be data capture and storage on a removable storage media such as a micro-SD card and can be uploaded to the Cloud. In this way, the user needs only retrieve the data when needed and can do so without going to the field.
