Arielle Walker Bo Yuan Sarosh Khalid Arsalan Ahmed Chris Hudy Wireless Sensor Data Team 2 Acquisition System 6

Project Description • 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. 7

Key Requirements 1. Operating Temperature: 15-60C & Humidity Range: 10- 90% rH 2. Battery powered sensor devices that can sense Temperature, Pressure and G-Force of environment 3. AD conversion circuitry with at least 8 bits of resolution 4. Data acquisition at a minimum of 500 Hz 5. Capability of enabling/disabling transmission of data 6. 5W maximum power dissipation 7. Proposed market price: $250 (including receiver hardware) 8
