Proximity Detection Sensors
- Created on Monday, 15 August 2011
Texas Advanced Optoelectronic Solutions® (Plano, TX) has announced its 5th generation sensor family, the TSL2x72 Series, that delivers improved digital ambient light sensing (ALS) and proximity detection technology. The TSL2x72 Series enhances mobile products by providing ALS and proximity detection operation in environments over 60,000 lux (sunlight). Proximity detection enhancements consist of increased signal-to-noise performance and a programmable register which allows compensation for optical signal crosstalk. Power management is improved with an automatic power-down mode after interrupt, which provides a ‘run-once’ capability, and further reduces system power consumption. The TSL2x72 Series is based on the patented TAOS dual- diode architecture which enables the devices to produce accurate ALS and proximity detection results when operating behind spectrally distorting glass regardless of the lighting sources (e.g. sunlight, fluorescent) and intensity.
