Description
DATALOGGER, C, EMBEDDED

We are a small company that wants to develop a datalogger and software for it.
It will be used and sold as part of a meteorological station for gathering climate data.
We will need help with hardware and software.

Fist the hardware:
Datalogger has to be based on an existing development board in production that can be purchased in a company such as Sparkfun.
See for example http://www.sparkfun.com/commerce/product_info.php?products_id=8244

We will buy one board and have it sent to you as part of the project. You have to choose the board that will perform all we want.

There will be 8 analog inputs to the datalogger ( 2 counters and 6 Vdc inputs )
Board has to have RS-232 and USB at least. Better if it has Ethernet also.
A very simple key board will be needed. Also a simple display.
Datalogger needs RTC and watch dog timer.
Data have to be sent to some portable external memory such as na SD card or better a simple pendrive.

Some conditions that make the project easier include:
a) No problem with energy or power or trying to minimize consumption. The meteorological sites will have 110Vac and thus 12VDC available.
b) No problem with size. Or trying to shrink hardware. Datalogger can be the size of a shoe box or even larger.
c) No problem with speed. Number of data and sampling is very low. Data saved willbe hourly averages. So no need for fast ADC. 10 bits is enough but 12 is prefered.
d) Cost of all hardware for production must be below US$ 160.00 ( This does not include baterries or SD card or pendrive or interconnect cables. But must include all else such as keyboard and display.
e) Amount of data stored is very low . We need at least 200 days of data.
Each day will have only 24 sets of data that will include year month day hour and 8 sets of numbers such as for example 311.5 ( wind direction in degrees)

SOFTWARE
The datalogger must save data to the Sd card or pendrive in .txt if possible.
User takes this portable memory with data from datalogger and connects to his PC.
Data then has to be as text. .txt
Data has to be easily exported to excel .
If user takes his notebook to datalogger he has to be able to configure the analog signals , change date and hour and several other configurations.
User has to be able to see instantaneous data in his notebook or palm when connected to thru USB with datalogger.

Shortlisted Decline Bid mistery   Gliwice, PL location US$1,200 bid amount (No Feedback Yet) feedback 20 day(s) delivery time     I am a student of Computer Sciences,Electronics and Automation Control at Silesian Technical University, Gliwice (Poland). I have 5+ years of experience in software development (commercial and hobby) for computers and microcontrollers (Atmel AVR's and ARM, 8051 and Hitachi/Renesas H8). I also have few years of experience in electronics and hardware design including EDA software like Protel and Eagle. I have developed similar datalogger as a university project. For this project I was using Olimex dev. board SAM7-EX256 ( link will be posted in private message ) This board seems to be identical with board you proposed for this project. I can complete this project within 20 days. If you want to import data to excel the software can create excel files directly (*.xls or xlsx - for excel 2007) or csv/txt that can be imported to excel. Please contact me if any additional information is required. Bid Time: 12-28-2007 17:42
