This week, the electrical team met with Professor Derek Wright for a circuit design review! He was able to speak to configuring sensors and directed us to Professor Carol Hulls for more information on sensor fusion.

We tried to find as many digital I2C sensors as possible to make testing the prototype as plug-and-play as possible. However, we were only able to find a fitting temperature sensor under those requirements. We also discovered that sweat/moisture sensors are actually an area that is still under development! In the end, we went with a simple analog circuit that measures return voltage through the skin.

We also visited Ridigware in E7 to grab some analog sensors and an STM32f401RE MCU.

To see more details on the sensor selection and how the final circuit schematic turned out, please see the FDP section from Nov 27th!

This is what the early stages of the circuit thought process was like…
