Data logger with arduino

  • Can Arduino be used as a DAQ?

    If you only need to collect simple data, like from an accelerometer or temperature sensor, we can create our own DAQ device from an Arduino.
    Additionally, we can step up to the professional Binho Nova host adapter to act as a DAQ as well..

  • Can Arduino be used as a data logger?

    In this tutorial, we're going to make a simple data logger using Arduino.
    The point is to learn the very basics of using Arduino to capture information and print to the terminal.
    We can use this basic setup to complete a range of tasks..

  • Can Arduino send data to PC?

    You can send debug messages from Arduino to the computer and display them on your computer screen.
    The Arduino IDE (described in Recipe 1.3) provides a Serial Monitor (shown in Figure 4-1) to display serial data received by Arduino..

  • What do you use a data logger for?

    A data logger is an instrument that monitors and records changes in conditions over time.
    They can be single, stand-alone units or consist of multiple channels.
    Most stand-alone units are battery-powered, allowing them to record while in transit and for extended periods of time..

  • What format is Arduino data logging?

    Data is logged onto an SD card in . csv format.
    You can connect the external circuit to an LDR to log light intensity in a room.
    Alternatively, you can utilize other sensors..

  • What is Arduino data logger?

    A data logger is a device that records sensor information at regular intervals over a period of time so that information can be analyzed to understand phenomenon that are hard to observe directly..

  • Many professional DAQ devices are easily a few hundred to thousands of dollars.
    If you only need to collect simple data, like from an accelerometer or temperature sensor, we can create our own DAQ device from an Arduino.

Code

Copy the following code to your Arduino IDE and upload it to your Arduino board.
View raw code In this code we create a loggingTime() function and a loggingTemperature() function that we call in the loop() to log the time and temperature to the DATA.txtfile in the SD card.
Open the Serial Monitor at a baud rate of 9600 and check if everything is wo.

Getting The Data from The SD Card

Let this project run for a few hours to gather a decent amount of data, and when you’re happy with the data logging period, shut down the Arduino and remove the SD from the SD card module.
Insert the SD card on your computer, open it, and you should have a DATA.txtfile with the collected data.
You can open the data with a text editor, or use a spre.

How does a data logger work?

Essentially, the logger reads sensor data and records the readings over time.
In our project, the sensor array for the data logger is provided by a TI SensorTag that operates as a battery-powered BLE peripheral.
To read the SensorTag, we use an Arduino 101 operating as a BLE central device.

Schematics

The following figure shows the circuit’s schematics for this project.
Note: make sure your SD card is formatted and working properly.

What is a ds3231 data logger?

The data logger is made up of the Arduino Nano, the Ds3231 RTC Module, and a micro SD card module.
The micro SD card module communicates with the Arduino over SPI as explained in a detailed tutorial here, while the DS3231 module communicates with the Arduino over I2C.
A detailed tutorial on the DS3231 module can also be found here.

What is an Arduino based data logger?

For today’s tutorial, our focus will be on building an Arduino based data logger that reads the temperature of the environment every few minutes and saves the data in a micro sd card.
The Project is based on the Arduino nano and the DS3231 RTC Module which has a temperature sensor and a real time clock on board.
