smartphone with so2 sensor

This work reports on the first deployment of PiCam devices in one such field: UV remote sensing of sulphur dioxide emissions from volcanoes; such data provide important insights into magmatic processes and are applied in hazard assessments. Recently, we reported on the development of lowcost ultraviolet (UV) cameras, based on the modification of sensors designed for the smartphone market.
