Taos uses programmable signal-gain modes, including a reduced-gain mode, to boost the dynamic range of the light sensors. Meanwhile the company boosted the signal-to-noise performance and added crosstalk-compensation technology to deliver more-accurate proximity detection. Both sensor types can be used sporadically while remaining in sleep mode much of the time to minimize power consumption – especially important in any battery-powered application.
The sensors work with any type of light source including fluorescent and at virtually any lighting level. Moreover the dual-diode architecture can provide accurate results even when mounted behind glass that can distort the spectrum.
