Pressure Sensing Microcontroller Board Hardware: The board will have: 1 serial port, TTL Level and RS232 Level connections available 2 LEDs 2 push buttons external or internal on board not decided yet 1 LCD with minimum 6 numeric digits with decimal point 1 RTD thorugh hole type 2 Analog (A/D) inputs for (minimum 12 bit) for two pressure sensors (50 psi digikey part 223-1148-ND) 5Volt Supply, 0.5 to 4.5 V analog output) OR (50 psi GEMS Sensor: 3103 SERIES PRESSURE TRANSDUCER) 5Volt Supply, 0.5 to 3 V analog output) Power input to board 5 to 6VDC, Maybe accept USB power also. Board layout long and narrow for installing inside an aluminum pipe housing 2" in outer diameter. Software: Board is normally powered down (consuming 0.00ma) but come on when "Power" push button is pressed Board remains on for 5 to 10 minutes unless someone presses the power push button again which causes the board to shutdown. The board reads both pressure sensors and RTD about 5 times a second and calculates a result based on a calculation that I will provide. The result is displayed on the LCD and refreshed 5 times a second. The result is displayed on the LCD as a number from 00.000 to 29.999 The reading is also sent out over the serial port as a number in ASCII format at 5 Hz Pressing the "Zero" buttom causes a zero of the offsets in both pressure sensors and assumes that the two readings match

Hi, Looks like a straightforward and interesting project, and well specified, (thankyou for that). I have had many may years in product design, mostly in microcontroller based instrumentation A few things, You suggest that the board will be powered by an external supply or a possible USB source but items of you specification suggest you may be intending it to be battery powered, is this your intent? The board has to fit within a 2' dia tube. Is this tube to be the primary housing of the device? or do you expect the device to be seperatly housed such that the display and buttons can be arranged in a fixed geometry? I would plan on delivering the schematics and artwork for the designs along with any code associated with the project and at least one physical prototype built and tested. Regards and good luck with your project. James Harrison-Smith Infonics

Hi, I can design for you this small board. I will use a PIC CPU with 12bit ADC integrated. In addition: I will implement analog RTD measurement circuit(which I have designed many times) Serial connections and LED are obvious. Power button - I will design it in this manner: long press (for more than 4 sec) - power of. than short press - power on. Based on my experience (13 years) I can do it in a month, give or take. Including the software. I can start next week. But the budget is certainly more than 750$. See my bid. Call me if you need to know more about me or to see previous designs of mine. Thanks, Amir
