Harvester Power Generation

The Solar Harvester generates power based on the amount of light striking the surface of the photovoltaic panel on the harvester. The harvester will generate sufficient energy to power the SmartDiagnostics® sensor nodes with as little as 500 Lux of ambient light. The amount of energy harvested increases with more light as shown in the chart below.
