2. Network Embedded Systems Mastermind: Prof. Koren

3. Background Sensors: wireless, self-powered Computer: data collection and evaluation Display: temperature graphs and maps

4. Project Specifications Collect changing temperature at all nodes Wirelessly transmit this data to the computer Computer collects, analyzes and stores data GUI displays any change in temp as reflected in the database

5. 1. Sensors (motes) TinyOS Components: Timer – sense and transmit at 5Hz A-D Converter – relay signal from thermister to radio as 8-bit temp. Comparison – Check for change in temperature, if different from archived data, transmit current reading Radio – establish data transfer w/ computer link, send temp. TIMER RADIO THERMISTER A-D CONV. READ TEMP READYDATA Comparison SENDDATA

6. Computer TimeTemp 000025 F 000129 F 000235 F Tiny OS File Master Database -Individual Motes (Time, Temperature) Query -Lastest Data from each mote (mote no., temp) RF Module GUI MoteTemp 135 F 267 F

7. GUI – final product Current Date: Wednesday, July 15, 2015Time: 05:17:12 From computer

8. Demo Design Sensor motes in boxes heated by light bulb Chronicle and monitor temperature data

9. Objective – by December! Part 1 – Computer TimeTemp 000025 F 000129 F 000235 F Tiny OS File Master Database -Individual Motes (Time, Temperature) Query -Lastest Data from each mote (mote no., temp) RF Module GUI MoteTemp 135 F 267 F

10. Part 2 - GUI Current Date: Wednesday, July 15, 2015Time: 05:17:12 From database
