1 C TinyOS Platforms Panel: MICAz1UC Berkeley / Feb 11, 2005 Basic Anatomy of a Crossbow Node

2 C TinyOS Platforms Panel: MICAz2UC Berkeley / Feb 11, 2005

3 C TinyOS Platforms Panel: MICAz3UC Berkeley / Feb 11, 2005

4 C TinyOS Platforms Panel: MICAz4UC Berkeley / Feb 11, 2005 MICAz Platform MICAz Platform Microprocessor: Atmel ATmega128L MHz clock 128 kB of Flash for program memory 4 kB of SRAM for data and variables 2 UARTs (Universal Asynchronous Receive and Transmit) Serial Port Interface (SPI) bus Dedicated hardware I2C bus Radio: Chipcons CC2420 External serial flash memory: 512 kB 51-pin expansion connector Eight 10-bit analog I/O 21 general purpose digital I/O User interface: 3 programmable LEDs JTAG port Powered by two AA batteries 1850 mAh capacity Logger Flash ATMega128L controller Analog I/O Digital I/O Freq. Tunable Radio 51-Pin Expansion Connector Antenna MMCX connector LEDs Now FCC/ARIB certified

5 C TinyOS Platforms Panel: MICAz5UC Berkeley / Feb 11, 2005 Microcontrollers and the ATMega128 Careful consideration required when comparing different processor cores on systems performance Wake up from sleep 1 sec. With the ATMega internal oscillator enabled: XMesh does this automatically. Wake up > 200 sec when using the external oscillator. Sleep current of 10 to 15 A Battery performance in a Mesh is not limited by this difference Operating voltage Minimum input voltage specified at 2.7 V Most sensors and I/O devices wont operates to 2.5 V Practical experience shows ATMega128 operates to 2.3 V Note: Chipcon radio typically doesn't operate below 2.1 V

6 C TinyOS Platforms Panel: MICAz6UC Berkeley / Feb 11, 2005 MICAz Roadmap 8 kB SRAM Further reduction in sleep current MICAz Postage Stamp July 05 release date Significantly reduced cost Surface mount (SMT) package

7 C TinyOS Platforms Panel: MICAz7UC Berkeley / Feb 11, 2005 Sensor and Data Acquisition Boards

8 C TinyOS Platforms Panel: MICAz8UC Berkeley / Feb 11, 2005 Typical Solution Select Sensor type based on Application Temp/Humidity/Light Security Industrial …. Xlisten + PostgreSQL Database MICAz Mote network w/ XMesh Routing Mote-VIEW Client Tools

9 C TinyOS Platforms Panel: MICAz9UC Berkeley / Feb 11, 2005 Software Architecture

10 C TinyOS Platforms Panel: MICAz10UC Berkeley / Feb 11, 2005 Deployment Overview Remote Database: Use Mote-VIEW to view data logged at a remote location Gateway: Forwards data from sensor network to server. Proxy Logging: Use serial forwarder to log readings from a remote gateway in locally. Local Logging: Store data from local gateway to a local database and view it all on one machine.

11 C TinyOS Platforms Panel: MICAz11UC Berkeley / Feb 11, 2005 Data Visualization with MOTE-VIEW
