Tech talk part 1: Electronic "doctor" tracks health of monitoring stations
Detailed Description
A volcano-monitoring station "health monitor" developed by CJ Moniz at the Hawaiian Volcano Observatory (HVO). It consists of three programmable circuit boards (bottom row), voltage sensors (top row), a current sensor (top right corner), and a custom-made voltage sensor for a 48VDC system (tan circuit board on the bottom right). This unit is deployed in a watertight box to help the electronics withstand harsh environmental conditions. USGS photo.
