Electro-optical sensors are used whenever light needs to be converted to energy. Because of this, electro-optical sensors can be seen almost anywhere. Common applications are smartphones where sensors are used to adjust screen brightness, and smartwatches in which sensors are used to measure the wearer's heartbeat. WebOptical DO Sensor When an optical DO sensor is immersed in water sample, oxygen crosses the membrane and interacts with the dye. This quenches or reduces the intensity and lifetime of the dye’s luminescence, which is measured by the photodetector and used to calculate the DO concentration.
