We design and build hardware, software, and firmware for open-source environmental monitoring systems. We specialize in low-power, modular systems. Our Arduino-compatible designs have been deployed across the lakes of Minnesota, mountains of Colorado, glaciers of Patagonia, high Andean desert, and Mississippi River delta.
