ams OSRAM TSL2740 ALS & Proximity Light-to-Digital Sensor
ams OSRAM TSL2740 ALS and Proximity Light-to-Digital Sensor features advanced proximity measurement and digital ambient light sensing (ALS). The proximity detection feature provides object detection via photodiode detection of reflected IR energy. Detect/release events are interrupt-driven and occur when proximity results cross upper and/or lower threshold settings. The proximity engine features offset adjustment registers to compensate for unwanted IR energy reflection at the sensor.Features
