6. Manometer spreadsheet explanation -Mr. Foye
7. Wrap up and order any needed components
Today we took a deeper look into a few different pressure sensors by discussing the pros and cons of each sensor and how each could work with our project. After careful consideration, we decided on one of the sensors to begin working with. We also talked about soldering the sensor to a breadboard instead of soldering the wires directly onto the sensor. This will result in more stability and at this time, we are not as concerned about our monitor being small as much as we are concerned with it working well. Along with the sensor we want to solder the regulator onto the breadboard. We began soldering the sensor to the breadboard and constructing our experimental model. An LED is going to be added so that we know when it is working.
