Dataloggers and data recorders
Sparkfun GPS logger shield converts your Arduino board into a wonderful logger board.
Sparkfun OpenScale measures both temperature and weight with operating voltage of 5V.
Here's a handy Arduino shield: we've had a lot of people looking for a dedicated and well-designed data logging shield.
The Logomatic v2 takes everything we learned with multiple logging projects over the years and boils it down to an easy to use device, that is now more adaptable than ever! Version 2 incorporates the LPC2148 with USB, battery charging, and microSD support.
This GPS shield works great with either UNO or Leonardo Arduinos and is designed to log data to an SD card.
OpenLog is an open source data logger. Simple to use, simple to change. We wanted to create a serial logger that just worked. Power up this device and it will start logging any received serial data at 9600bps. Sending Ctrl+z three times will drop out of logging and in to command mode.
