MCU & Sensors

• PIC 16F877• LM34 – Temperature Sensor• NovaSensor NPT-410 – Pressure Sensor


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


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.

Graphical User Interface


• 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

Wireless Transceiver


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

Temperature Comma Pressure Reserved

32 Character Data PacketASCII String formatted, comma separated fields


Power

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

input
