Data


Acquisition

Development of the SODA HE 1.0 was supported in part by the National Science Foundation under Grant Number 1238246.
What makes the SODA HE 1.0 different?
The HE 1.0 is designed to make data logging easy.  It has all of the components need to measure and record environmental variables. It also has a unique power circuit to make batteries last a long, long time. The SODA library let's you program the board for a data logging mission in just a few minutes.
