  2. MCU & Sensors • PIC 16F877 • LM34 – Temperature Sensor • NovaSensor NPT-410 – Pressure Sensor

  3. MCU &HI-TECH C Code • Using HI-TECH C-compiler to program our PIC • Learning curve, but we are catching on quickly • Important resource: http://www.workingtechnologies.com/htpic/Hi-Tech_C_sample_code.htm

  4. Graphical User Interface • Important Characteristics • Uses Visual Basic 6 component model. • Basis for serial communications is the Active X component called MSComm. • MSComm allows program to open/close and setup a serial port (i.e. Com1). • Data packet from PIC is parsed and temperature and pressure can currently be displayed. • Next Steps • Add graphical representation of data through National Instrument’s Active X components. • Add GPS and other sensor data to display.

  5. Wireless Transceiver • Aerocomm AC5124C • 400 mA transmit • 115 mA receive • 10,000 ft line of sight • 1.65” x 2.65” x .20” • Less that ½ ounce

  6. Wireless Transceiver • Aerocomm AC5124C • 400 mA transmit • 10,000 ft line of sight • 1.65” x 2.65” x .20” • Built in Error Correction • RS-232 Interface available through Serial Interface Board • Transparent mode of operation • Running at 9600 Baud 32 Character Data Packet ASCII String formatted, comma separated fields

  7. Power • Required 5V and 10V for the circuit • Solar Cell provides 10V and 2mA • Use voltage regulator for parts that need a 5V input
