For this project, our team has several challenges:

  1. How to detect the water level?

  2. How to detect the volume of people's drinking and refilling?

  3. How to make it ambient and unobtrusive?

When we decided using a DIY water level sensor, we began to follow the reference to make the product. We finished the circuit, but it was really hard to complete the code part. Jiangtao made a heavy contribution in that part by asking for professor's and classmates' help. The code also needs to be iterated in different versions. For instance, we tried several times to define the baseline of water level detection, 2270, 2300, ......

After a series of iterations, we made a successful outcome for our project.

  • We tried several circuits with different components.
