I have developed some load cells that create an amplified 0-5V analogue value. The voltage will processed by a 12 bit ADC. I need a time stamped reading to be logged every 20 milliseconds(!), alond with temperature, and stored in a file that records 24 hours of data (consecutive duplicated data is not recorded in order to reduce the file size). Every day the file must be uploaded to a server via a WiFi connection. If the server is not available then the file will be held for up to 7 days and an upload attempted each day. At the moment I am using an Arduino Duemilanove to interface with the load cells and output the data via the USB serial connection. I need to work with somebody to develop the Raspberry Pi to interface with the Arduino and write the software to save the files, manage them and upload them. All program to be held on the Raspberry Pi SD card so that upgrades can be offered by simply replacing the SD card.

Hello, I would like to help you out with this project and i think i am the right person for you. I have very good experience with Raspberry Pi (did recently projects involving Raspberry and : reading data from sensors, measuring sound db, stand alone units, mouse only interface, routers+mini web server, ...). I also have all the hardware needed (both models of Raspberry, sd cards, additional hardware). We will need to discuss a few details, but your project is precisely in my area of expertise. I am ready do start whenever you want. Regarding updates i have a solution that can be even better than replacing the SD card (it's working right now on a few units i have)
