3. Cyclist Power Meter

4. Auto Green House
The purpose of this project is to make an all in one controller for a green house. In the block diagram there are nine blocks.
Power Supply: Supplies power to every other block, except the wireless output.
Input: User interface, user will be asked to set system requirements.
Lights: Controls amount of light exposure.
Humidity: Controls humidity and watering in the green house.
Temperature: Controls temperature regulating and air flow, looking for
consistency throughout the green house.
Wireless Transmitter/Receiver: Sends and receives output information to wireless output device.
Power Supply 2: Powers the output device.
Output: Outputs current readings in the green house.

5. Pulse Oximeter and Respiratory Monitor for Laboratory Rats
-Detection of blood oxygen level using absorption levels of LED wavelengths.
-Monitoring Heart Rate and Respiratory level

6. Selection Matrix

7. Recommended Project
-An Instrument To display Blood Oxygen Content, Heart Rate and Respiration Rate of a Laboratory Rat using oximetry.
-The monitor should be able to display a reasonable range for a typical rat pulse and percentage of oxygen level.
-There are no currently known similar products on the market for the use on research rats.
