  5. ADK Software Flow RS-232 ADK (Seeed Studios ATMega2560 with integrated Host Shield) Example Iridium Connector Shield

  6. SMC Software Flow

  7. Master Node Communication

  8. Sensor Node MSP430 Embedded Software Flow Diagram

  9. Humidity Sensor • Thermoset polymer, three layer capacitor construction • Integrated Resistive Temperature Detection for Temperature Correction • Condensation-Resistant Hydrophobic Filter Honeywell

  10. Accelerometer • 3-Axis, 8-bit Digital Accelerometer (I2C) • ±2g/±4g/±8g dynamically selectable full-scale • Output Data Rates (ODR) from 1.56 Hz to 800 Hz • Two programmable interrupt pins for seven interrupt sources • Automatic ODR change for Auto-WAKE and return to SLEEP 16 PIN QFN 3 mm x 3 mm x 1 mm

  11. Block Diagram

  12. Pressure Sensor • I2C communication • Simple barometer with digital output and high performance • Accurate to ±1 kPa over the 50 kPa to 115 kPa pressure range • Write Mode • Start sequence->7bit slave address | slave ACK then writes • Read Mode • Starts with Start sequence -> Stop Condition

  13. Block Diagram

  14. Pressure Calculation Pcomp = a0+(b1+c11*Padc+c12*Tadc)*Padc+(b2+c22*Tadc)*Tadc Where: Padc is the 10-bit pressure output of the MPL115A ADC, Tadc is the 10-bit temperature output of the MPL115A ADC, a0 is the pressure offset coefficient, b1 is the pressure sensitivity coefficient, c11 is the pressure linearity (2nd order) coefficient, c12 is the coefficient for temperature sensitivity coefficient (TCS), b2 is the 1st order temperature offset coefficient (TCO), c22 is the 2nd order temperature offset coefficient.

  15. Light Sensor Vishay/Semiconductors TEMD6010FX01 Anode • Ambient Light Sensor Miniflat SMD • Dimensions (L x W x H in mm): 4 x 2 x 1.05 • PIN photodiode type • High speed and high photo sensitivity in a clear, surface mount plastic package. Cathode • Peak sensitivity wavelength at 540 nm. • Conversion will be done using the internal A/D Converter of the MSP430. • Light will be measured in different levels: Detecting Low level, Medium level, and High level light.

  16. Moisture Sensor Three Options of Sensor: • Two Rods • Two Copper Tracks on PCB • Wires between paper sheets Moisture Sensor MSP 430 • The conversion will be done using the internal Comparator of the MSP430 MCU. • Sensor dimensions may vary and are dependent on the required conditions.
