Module 4: Tying It All Together

Welcome to the fourth module of our Build Your Own Data Logger virtual course. In these videos, we'll tie everything we've learned so far together by creating our functional data logger application.

Our course directory has a full list of modules and videos with links. Follow our Build Your Own Data Logger playlist on our Youtube channel to catch every module as it goes live, and register for our full course to be the first to know about our module releases, live Q&A events, and course news.

In Module 4, we tie together everything we’ve learned so far into a functional datalogger application. We’ll be implementing the temperature and humidity sensor, realtime clock, analog digital converter, SD cards, PIR motion sensor, and command line interface to implement a test version of our datalogger. We’ll then test it for functionality and check that we have things in the desired format.

In the second part of this module, we learn that everything fails and why it’s important to prepare for this. We’ll add additional safety checks to prevent what we can, diagnostic logs for documenting errors after the fact, and error codes which will be important for both fieldwork and forensic studies when a device fails in the field. 

This module will be code heavy since we’re not introducing any new concepts, but integrating a lot of things together.

Coming up in Module 5

Next module, we'll learn how to optimise the application, looking at power savings and adding a watchdog timer. At the end of this module, the deployment code will be ready!
