Components and Assembly The extendable Arduino GPS data logger consists of a shield that is fitted with the GPS receiver, SD card reader, and accelerometer, together with an Arduino UNO board.

Once it’s running, the logger will read up to six sensors and record them to an SD card. In the video after the break he shows the method used to dump and graph the data.

There’s also an SD card thrown in for good measure, making this one of the best tracking and data logging shields for the Arduino.

The Mayfly Data logger is a fully programmable microprocessor board which is fully compatible with the Arduino IDE and is equipped with a Atmega 1284p processor supported by 128K flash memory and ...
