Hydrologic Sensors – Benjamin Trustman, Founder. I always saw the idea of remote recording as a valuable concept. My early career in mobile audio recording helped me define the idea, and gave me the knowledge to understand the linear connections of source to storage data. As a student in Hydrology, I worked in several labs honing my field application skills. The one constant pressure in academic research is budget constraint. When I was presented the challenge of creating an affordable way to measure snow without a large fluid filled pillow, I jumped at the opportunity. Now, with over a decade of experience in remote hydrological measurement applications, I am expanding the field of low cost sensor applications.
