OpenLog - data logger - SparkFun DEV-13712

• What are the actual values measured by the sensors?
• What temperature is reached by the system closed in the case when it is unmonitored?
• What are the values of the accelerations detected by accelerometer?
• Where actually was the GPS receiver?

All these questions will be answered by OpenLog. The device is used to record data directly onthe microSD card.With a main module (for example, with anymicrocontrolleror a set ofArduino) communicating via simple serial interface (RX and TX pins). The modulesupports cards of up to 64 GBwith the FAT16 and FAT32 file system.

The set does not containgoldpin connectors of 2.54 mm raster, you can buy them separately and solder yourself.

The device should be connected through a serial UART interface - RX and TX pins. After powering up and sending data, the OpenLog will start to record them onthe card. The default transfer rate is9600 bits / sec. To enter the configuration mode, you need to download three times the sequencectrl+z,command"new"creates a new file,"md" - new folder. The configuration fileconfig.txt,which is located on the memory card, can be edited from the computer. This allows you to easily select the operation mode and to set the transmission speed.

The use of the system is simplified by the sample programforArduinoanda list of available commands. Users of the module may also use the preparedlessons. Description and sample programs are also on theGitHub.

In our offer is also the corner,1x6 female connector, allowing for the direct connection of the module OpenLog, for example, to Arduino Pro.
