I have the SM-24 geophone (https://www.sparkfun.com/products/11744) but I don’t have a clue how to interface it with an arduino or other system to log vibrations to an SD card. Any schematics available for this similar inputs? I am not sure of the voltage range… it says 28.8 V/m/s.
Thank you!
Hello, and thanks for posting!
We don’t have an interface for the SM-24 for Arduino, but if you check our example code link on the product page, there is a schematic and Eagle files for building your own Arduino shield to connect the SM-24 to a Uno. (Link below)

For logging to a SD card, you could either use something like the [OpenLog or the [Micro SD Shield.](SparkFun microSD Shield - DEV-12761 - SparkFun Electronics)](SparkFun OpenLog - DEV-13712 - SparkFun Electronics)
