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.
