Data Logging

Learn about data logging

A simple way to record, store and analyse environmental data. You can use the BBC micro:bit V2 with built-in speaker as a data logger, recording data from its built-in sensors. Data is stored on your micro:bit even when its power source is disconnected.

• Data logging projects

  Try out data logging in your classroom with three new projects

  With a few blocks of code, you can capture, store and visualise real-world data from the micro:bit’s built-in sensors for temperature, light, sound, movement and magnetism. Data logging enables your students to carry out meaningful scientific experiments, and to learn about how to collect reliable data, visualise and interpret it.

• Max-min temperature loggerTurn your micro:bit into a self-contained data logger that records maximum and minimum temperature readings, and stores them so it keeps the data even if the batteries run out or you disconnect the power.
• Recording Light/Temperature
  This code will make the micro:bit forever send the light level data (with the label “x” on it) up the USB cable to your computer. You’ll notice the simulator on the left of the screen has changed slightly – there is a purple button which says “show console – simulator”. We can click on it and look at what datalogging looks like.
• Wireless Remote Weather Station with micro:bit
  
  In this tutorial, we will utilize MakeCode’s radio blocks to have one micro:bit transmit a signal to a receiving micro:bit on the same channel! This is useful if your weather station is installed in a location that is difficult to retrieve data from the OpenLog. We will explore a few different ways to send and receive data.
• Remote data collection
  A simple way to record, store and analyse environmental data
  You can use the BBC micro:bit V2 with built-in speaker as a data logger, recording data from its built-in sensors. Data is stored on your micro:bit even when its power source is disconnected.
• Writing Data 
  While you’re using MakeCode, all data written by the serial functions is recorded by the MakeCode editor. This happens when you try your code in the simulator and also when the micro:bit is connected to a computer running the MakeCode app with USB

• Beyond the Basics with micro:bit – Exploring the Data Logger using the V2 (YouTube Video)
  “Do you have prior experience coding with the micro:bit? Are you curious about using the micro:bit sensors and new V2 data logger to record, store and analyse environmental data? Lisa Anne Floyd will provide step-by-step instructions to collect data using the micro:bit V2’s built-in sensors. Through incorporating the Data Logger extension in MakeCode, students can collect data over a period of time and create visualizations to represent the data. Students can then apply these tools and skills in their science and technology investigations, as they conduct experiments or engage in the engineering design process. Recommended Experience/Grade Level: This session is geared towards educators of grades 4-8 who have prior experience coding with the micro:bit.
