The IR (infra-red) proximity sensor detects proximity by beaming out infra-red light and detecting how much of the light returns. The biggest limitation of this technology is that there is no reliable way to turn the reflectance values into distances unless both the item being detected and the ambient conditions are known. \section2 QIRProximityReading Units The sensor reports reflectance as a percentage. That is, 0 indicates nothing was detected within the range of the sensor and 100 indicates the infra-red signal returned at the full power level that it was sent at. */ /* \property QIRProximityReading::reflectance \brief Holds the reflectance value.
