Meeting with Your TA

Description

By the Thursday of the third week, you must have a project approved, and should be ready to get working! At this time, you'll need to log into PACE and submit your schedule for the semester. Please be sure to make this as accurate as possible because once it's submitted, it can only be changed manually. Making a block of your schedule red means that you are unavailable during that time.

Once each person on your team has submitted their schedule, your TA will be able to easily check for available times to schedule a weekly meeting. Your TA should contact you, usually by the fourth week, via email, to set up a weekly meeting schedule at mutual convenience. During the first weekly meeting, your TA will assign your team a locker and a lab kit.

Weekly meetings with your TA are required and will be held throughout the entire semester until demonstrations are completed. Your TA is your project manager. The "homework" of the course consists of preparing for the weekly meetings. Your TA will evaluate your lab notebook each week, provide feedback, and recommend improvements. At each meeting you will be expected to present your progress since your last meeting, plans for the coming week, and any technical or administrative questions you need to discuss with your TA. You are expected to arrive on time and prepared to make good use of your time with your TA. Your TA may require that each team member to fill out the Progress Report Template and submit it to them prior to each weekly meeting.

Requirements and Grading

Attendance and participation in weekly meetings is required and will affect Teamwork and Lab Notebook scores. If you can't make it to a particular weekly meeting, it is your responsibility to inform your TA prior to the meeting time and set up an alternate time.

Submission and Deadlines

Your schedule must be submitted by the end of the third week of class and you will receive an email from your TA shortly after. Your first meeting with your TA should be during the fourth week of the semester.

A crowd-sourcing urban air quality monitoring system with bikes

Featured Project

**Problem**

For public bike users, someone may concern about the air quality in which they are currently riding, as well as the places they are going to. However, currently there is no such an air quality monitoring system which provides air quality information in specific areas inside a city such as Haining.

**Solution Overview**

The idea is to apply air quality monitoring devices on the public bike system. The public bike system in Haining is a perfect carrier for IoT (Internet of Things) devices and urban sensing since it has a large and stable user group and all bikes are managed by official organization which means unified modification on all bikes can be done. A monitoring device integrated on the bike can provide the real-time information that users want to know and share data with other users through a cloud server. A real-time air quality map can be created for users with the contribution from all running bikes.

**Solution Components**

Subsystem 1 – on-bike air quality monitoring device. The subsystem is a stm32 microcontroller based design, integrated with air contaminant sensor, speed meter and data transmission modules. Once connected to a smartphone, the subsystem will keep transmitting real-time data to the smartphone.

Subsystem 2 – Software include a user interface and a server. The user interface can be either an app or a website on smartphone. The user interface receives sensor data from the hardware subsystem, displays the real-time statistics, uploads sensor data to server and receives the air quality map from server. The server processes data from all running bikes, creates a real-time air quality map and returns it back to users.

**Criterion for Success**

1. Success of data collection: stable real-time statistic display on user interface, stable data collection on server.

2. Air quality visualization: The air quality map correctly reflects the air quality in Haining city. For example, the concentration of air contamination should be higher in heavy traffic than in intl campus.

3. Speed control: The on-bike device or smartphone should give an alert when the monitored speed exceeds the upper limit or the user set range. This is not the core function of our design, but we add it as we think the function makes sense for safety purpose.
