Data logging shield

Using this module, you can register and store measurements of various sensors. The board can be used in projects where it is necessary to collect information from sensors for a long time. The accumulated data is stored on the SD card in a file that can be used to plot graphs in programs such as Microsoft Office on a personal computer.

A DS1307 real-time clock module is built into the board. To operate the DS1307, you must insert a CR1220 battery into the holder. The battery provides the clock with more than one year of operation. The DS1307 module is designed to accurately record the time of each measurement.

You can use an SD card as storage. Power is supplied to the SD card through the RT9193-33 chip. The chip has a voltage regulator installed, so it supplies 3.3V to the card.

The Data logging shield is connected to the Ardunino Uno board by surface mounting, which ensures the absence of a large number of wires. All unused outputs of the microcontroller device are connected to the module board in the form of connectors. The RESET button resets the entire module system.

At the top of the board are the contacts:

3V: stabilized voltage
SQ: pulses from the output of the real time sensor.
WP: a signal that indicates the presence of write protection on the SD card
CD: indicates the presence of a card in the holder.

At the bottom of the board is a group of 3 pins:

CS: signal that is supplied from the SD card.
L1 , L2: LED control pins (LED1 and LED2).

The module board has a breadboard field that serves to connect sensors and construct electrical circuits by soldering.

Before assembling a breadboard, you need to download libraries for working with an SD card and a real-time sensor. After installing them, you can start collecting a breadboard and writing a sketch for your project.
