Project Description

7

• Sensor inputs from the environment are digitized and sent to a microcontroller through a wireless module (using appropriate protocols).

• This design is to be used for CT scan imaging machines in a high speed rotating environment.

• Using the wireless transmitters we would eliminate costly wiring and allow flexibility in the location/placement of these sensors.

Key Requirements

Water Purification Control

System • This System is mainly for the region where there is a lack of

access to clean water.

• This design is a 3 stage water purification system.

•Stage 1 is the clarity stage

•Stage 2 is the ph stage

•Stage 3 is the ion stage

• It will also have a display to show relative numbers for each of

the three stages current levels.

• Display will also have light to show what stage is running.

Key Requirements

• Power: 10w

• Speed: 50Mhz

• Resolution: 10bits

• Accuracy: 90%

• Cost : $190
