[Jed Hodson] put together a nice little data logger with a Linkit One board at its heart. It’s capable of logging two analog channels and one digital channel which also has PWM capabilities. A GPS is used to get the correct time and a Freetronics OLED display coupled with a shield lets the user view the data in real time.
The data is logged on the Linkit One’s internal storage as a .CSV file, allowing for easy access via a spread sheet program. A LiPo rechargeable battery keeps the electrons flowing and the system will give a warning once the power drops below 20%. Speaking of system – the Linkit One board features an ARM-7 processor and has headers to fit Arduino shields. It’s targeted for wearable and IoT type devices.
Be sure to check out this project if you’re in need of a nice data logger. All code and details of the build are available on [Jed’s] Blog.
