Apogees’ customers find the coolest ways to use our sensors. This recent blog post from Voltaic shows how our popular SQ-520 USB full-spectrum quantum sensor can be connected to their 5V "always-on" battery pack for remote logging up to thirty days without interruption. This "always-on" feature is important because all of our USB sensors have such a low power draw that some USB batteries and power adapters shut down thinking nothing is plugged in. By using the Voltaic battery and enabling the on-board logging memory in our sensor, our USB sensors can be used almost anywhere!
