3
Goals

• Overall goal
• Inspire middle school girls to actively pursue an
  interest in science and engineering
• Quarter goals
• Mount particle sensor on Preuss school
• Interactive website

4
Long Term Goals
5
History

• Focus on particle sensor system
• Sensor curriculum

6
Timeline
7
Enclosure
8
Problem

• Moisture in the air can damage the sensor
• How can we remove the moisture?
• Heat or desiccant?

9
Analysis

• Heat
• Works continuously
• Better for long term mounting
• Requires a lot of power
• Desiccant
• Does not require power
• Better for testing
• Has to be changed often

10
Calculations

• Heat
• Amount of heat to prevent condensation
• Desiccant
• How long will it last?

11
Results

• Need 50 W of heat or,
• Desiccant can last 11 hours.
• Problems with calculations
• Can only estimate air flow
• Conditions change

12
Heating Sources

• Pads
• Requires too much power
• Automatic shut off
• Too big
• Coils
• Can be formed into a variety of
• shapes
• Built to withstand extreme conditions

13
Testing

• Can we get valid data from our sensor?
• How do we set-up/operate our system?
• Is our equipment reliable?
