Web26 de jan. de 2024 · Researchers Develop “Human-Eye” Like Sensor. Recently, researchers from Oregon State University have developed a semiconductor photo-sensor that operates more like the human eye than a standard camera. The new sensor is based on perovskite, and as such the sensor only reacts to changes in light levels instead of absolute levels. WebPhotocells work all year round, activating at dusk and turning off at dawn, even when the days are longer in summer or shorter in winter. As they sense the amount of light rather than operating at a set time, they don’t need to be adjusted when sunrise or sunset shifts with the seasons. Many outdoor lighting setupsuse motion sensors.
