Gravity - light and colour sensors

The designers at DFRobot have created the Gravity series, which includes high-quality hardware expansion modules that you can plug into an Arduino or other single-chip minicomputer. The Gravity series also includes color and light intensity sensors, whose design is based on photodiodes as well as UV sensors. By performing light intensity measurements and studying the color composition of light, we can build various devices triggered by such sensors. Such constructions include automatic garden lighting controllers, lighting effects, and advanced models of experimental robots. Light and color sensors from the Gravity series communicate with base modules via the I2C bus.
