Arduino Project: Data Logging DS3231 SD card module and Arduino Nano DIY data logger

Arduino Project: Data Logging with DS3231 RTC, SD card module and Arduino Nano DIY data logger - [Link]

by Husham Samir @ instructables.com:

A temperature data logger, is a portable measurement device that is able to recording temperature over a defined period of time automatically. The data can be retrieved and viewed after it has been recorded. In this device the temperature will record every one minutes in CSV file.

Charles Edward Pax has announced that the T400 temperature datalogger is now being offered on Kickstarter!

The Pax Instruments T400 datalogger is an open source four-channel thermocouple temperature datalogger based on the Arduino™ Leonardo platform. It is ready to use out of the box with the features you want most. Measurements can be logged to MicoSD card, printed to serial port, and graphed. The T400 is a great tool for anything from live thermal process monitoring in the lab to long-term environmental data collection in the field.

Adding USB functionality to your Arduino projects used to be a pain, but thankfully, the V-USB project came along and gave your ATMEGA328 the ability to control the USB lines directly and mimic simple (low-speed) USB peripherals. [Ray] shows an implementation of the V-USB project by logging the status of the Arduino’s I/O pins to an open Excel spreadsheet

V-USB (Virtual USB) is especially useful for those of us who build standalone Arduino projects with the ATMEGA328. Unlike the Arduino Leonardo and its ATMEGA32U4, the ATMEGA328 does not have a built-in USB controller. The circuit required to tie into the USB lines is made up of just a few basic components, and [Ray] provides a reference schematic and BOM to get you started. The Arduino is programmed to mimic a keyboard, so the datalogging is achieved by allowing the Arduino to ‘type’ the data into an open Excel spreadsheet. In this example, the status of 8 digital pins and all 6 Analog Input pins are logged.

For those of you who prefer the PIC microcontroller and are in a similar position of not having a built-in USB controller, there is the 16FUSB project to help you out.

Encore un projet dans les cartons. Concevoir un petit enregistreur me permettant de stocker sur une carte SD plusieurs paramètres lorsque je fais des sorties à vélo. Je souhaiterai enregistrer:

• La date / heure
• La position GPS
• La vitesse
• Le cap
• la cadence de pédalage
• l’accélération X Y et Z
• la température
• Le rythme cardiaque
